Last day of class! Three units in 11 days, instead of 15 weeks - phew! To their credit, all the students showed up today on time at 9:30am, and immediately flipped open their laptops and resumed analyzing all the data.
And we seem to have a lot of data! We did 11 soundings (a couple were funky, but most looked good). We also had a morning's worth of sodar data, and two sets of data from the RAWS, one lasting over 24 hours. This is something we'll have to think about in future - if you do all this storm chasing and instrument deployment, you get a ton of data, but no time to analyze it! We've given the students a couple of weeks to get their analyses finished up and turned in.
I'd like to thank the instructors - Mike Voss and Craig Clements - for all their hard work in making this a successful course. I'd also like to thank the students for being such good eggs! They all worked hard without complaint, and were fun too!
Thus endeth the blog. Thanks for reading!

Day 10 - a Sierra launch!
Day 10 dawned kinda early after our late excusion. I ate breakfast out and spaced on going to Schat's bakery. Apparently I missed something good!
Anyhoo, we drove north to Lee Vining, and then headed west over Tioga Pass. Craig Clements gave us an interesting mini-lecture on the diurnal winds of Lee Vining canyon. The story involves the Zephyr wind...look it up! And then on up to Tuolumne Meadows for lunch and a radiosonde balloon release. Hey - we got into the park for free! Something to do with having "CA exempt" plates. The balloon launch went spectacularly well, and we tracked the sonde up into the stratosphere. Of course, none of us thought to apply sunscreen, so there were some red faces the next day...
The drive down from there was pretty long. Long and winding road out of Yosemite, and then a high speed dash across the valley to home, arriving on campus at 7:30 pm. Most of the students in chase vehicle #1 slept and dozed all day - I think the students were pooped out by the trip. I know I was! In my case, it was party due to my excessive consumption of junk food on the last day in the van. As we all know, junk food consumed on the road does not count toward ones daily caloric intake. Road rule #1.

Collateral damages (finished!)
On a trip this long, there were bound to be a few boo-boos etc. Luckily, nothing serious! For example, the vans always started, and there were no flat tires. Most importantly, the A/C worked!
On the other hand, on the second drive day outbound, your truly was driving chase # 1 eastbound somewhere east of Barstow, when there in the road was a snake, stretched to its full length across my lane (i.e., perpendicular to traffic, which was unfortunate). I'm not sure if I hit it - didn't feel a bump, but the snake was wriggling like crazy in the rear-view mirror! But we're ALL sure that Dais, driving chase # 2, squashed it. And get this - Dais was all "what snake?". Score "1" for the team. And BTW, Dais' handle is now "snakekiller".
On the return trip, we overnighted in Bishop (and you know my thoughts on the hellacious drive that day). Originally we were going to do some field experiments in the region, but that idea didn't pan out, so we were left with just the Ramada Inn. BUT - it happened to be the peak night of my favorite annual meteor shower - the Perseids. Every year I make some kind of effort to get out and watch, the best ever being on a moonless night beside Lake Tahoe a few years back. Anyway, we assembled at 10:30pm, squashed ALL of us into the van (remember that Mike had gone home, so there were 12 of us), and headed uphill west out of Bishop. For Craig & I in the front seat, there was a spectacular "wow" fireball-like meteor. We pulled off the road in a large dirt area, and spilled all over the ground. Within about 10 minutes we'd seen a couple more really good streaks, and then some weaker ones. Meanwhile, a spectacular view east over the Owens valley and over Bishop in the distance, and the Milky Way was resplendent. ALSO, there was a gentle cool downslope breeze blowing steadily - so we could justify this as a meteorological outing!!!
OK, you say, where are the collateral damages in this story? Well, by midnight the moon's brightness was drowning out the sky, so we baled out. So there we are, bombing downhill at about 50 mph, lights on bright so I can see for miles (for you see, I am driving). And then a couple cars are coming towards me (note: this restricts me from swerving into the other lane)(unless we all want to die). So I dim the lights, and that's when an entire family of animals (raccoons? possums?) darts out in front of me. Larger animal (mom?) and two smaller ones. With the brights on, I might have seen them. With no traffic oncoming, I might have swerved (dangerous), but events conspired so that there was nothing I could do. THUMP. Thump, thump, thump. Score "2" for the team.
Here's the funny thing - we could have all sobbed all the way back to the Ramada, since I was pretty sure I'd killed mom. But no. The reaction of the day was peals of laughter! Go figure! Also, Craig, Jamie & Dais did a crazy sunrise hike the next morning, and drove past the same spot. Hence the confirmation: raccoon.
No other dead stuff that I know of (luckily, we saw the elk buck or else there would have been a big elk-shaped dent in chase #2).
The only other major trip damage was to shoes. At one point, one of Allison's shoes fell apart, and had to be repaired with duct tape. By the end of the trip, the other shoe had failed and also had to be repaired. Now, I don't know about you, but at this point I'm thinking "new shoes", but Allison had ruled this out due to being very fond of this particular pair of shoes. Perhaps in the mode of copycat, Steve P. felt the need to apply duct tape to his sandals during the trip, as they too were suffering. The duct tape was one of the last things we remembered to bring, but of course was vital!

Day 9 - a long drive
Day one of a two-day drive home. We had at one time planned a 24-hour stay in Bishop for some local wind studies. FYI, Bishop is in the Owens Valley along the eastern Sierra. Getting there from FLG meant a long drive west from FLG to Barstow, and then northeast/north through the Mojave to the Owens Valley. We left FLG at 9 am, and pulled into our hotel in Bishop at 7:30 pm - groan. Luckily at every hotel they have been ready for us, with a pack of room card keys ready to hand out.
On the FLG-Barstow leg, the speed limit in AZ was 75 - that helped! We had an interesting lunch in the small town of Ludlow, CA. We had a choice of a cafe and a DQ. I have always thought of DQ as an ice cream place, even tho' I have seen the DQ menu! But instinctively I chose the cafe (to Craig's continued irritation, continued as of Aug 13!) The two waitresses in their prarie dresses were a novelty; the food - average. I had eggs and potatoes - hard to mess that up.
As for the Barstow-Bishop leg, urgh. Don't get me wrong - I love the desert, but there was just nothing to look at, at least thru Lone Pine. I was getting suicidal by the end. Even the students were catatonic.
To save the day, we had a really nice dinner in Bishop - delicious Mexican food at Las Palmas restaurant! Highly recommended by all!
And then - drumroll - I dragged everybody out to see the annual Perseids meteor shower! We crammed all 12 of us in the van. Theoretically there are seatbelts for 12, but I would guess 12 small people! Anyhoo, the nice thing about Bishop is that a 10 minute drive out of town in any direction, and you're in almost wilderness, and there is plenty of dark to go around. As we drove westbound uphill, Craig and I saw an intense fireball in front of us. We found a good dirt area to park in, with a spectacular view east towards Bishop in the distance, with an orange half moon rising. Within about 10 minutes we had all seen really good meteorites, followed by several smaller ones.
By midnight the moon was bright enough to wash out pretty much everything, so we bagged it. Had a little incident on the way home, but you'll have to read the "collateral damage" blog to see what that was!!!

Day 8 - a day trip!
Day 8, and we have a veritable mountain of data to process! Not to mention that we are all busy with forecasting every day, meaning individual forecasting and team presentations.
Thus, we toook the morning to focus on data analysis. So far, we have RAWS data from two sites, sodar from one, and ten balloon radiosonde soundings. To slow things down (unplanned), the Matlab installation on the laptops didn't work. Something to do with accessing the license (and yes we did buy the software legally!) Anyway, there are always work-arounds.
In the afternoon, we felt it was necessary to take a quick sightseeing drive down to Sedona, which most/all of the students hadn't seen. In fact, many of them had not heard of this infamous "vortex site"! It's a fast, scenic drive down and back, so we just spent the afternoon.
We went out to Red Rock State Park (http://azstateparks.com/Parks/RERO/index.html) for a hike-ette. It was just under 100o, so we didn't stay out long. And when we got into town, there was a dash for the misting stations! Uptown was nice, and many souvenirs were purchased!
It's our last night! We went into downtown FLG for an asian fusion dinner at a restaurant called "Monsoon". Fitting since we were here to study the monsoon. Unfortunately this year we studies the non-appearance of the monsoon, but there's always next year!
No time to pack! Back to the hotel and back to work for the students to prepare their last forecast of the class. Another late night, with class 'till after 10:30...

Day 7 - morning PBL campaign
Today, I learned these things about field work. (1) You have to get up at zero-dark-thirty - not my idea of fun (unless it's for a flight to an exotic location!) (2) You might ram into something large on the highway due to driving while groggy. (3) After all the fuss, the stupid instruments might not work. On the plus side, you might see into something large and fun on the highway while driving, and you might get some good data, and have fun along the way!
OK...to elaborate! (1) We gathered at 5 am. Funnily enough, we had set the students free the night before, free to roam and graze alone in town. Specifically in the watering holes in town. This accounts for why they arrived back at the hotel at 1:45 am :-)
(2) One the way to the RAWS site, located 45 minutes northwest of FLG, and on the way to the Grand Canyon, we encountered a HUGE buck elk standing in the middle of the raod. MANY points. VERY impressive. The female in the road about a mile on was less impressive, but STILL...! If we had hit either, this would have been a big negative, but instead goes into the positive column!
(3) OK, so we arrive. Oh and by the way, the "managed" fire in the region had laid down overnight. Hence - huge smoke cloud at the surface. The RAWS site was luckily between the two thickest spots, otherwise we'd probbaly still be lying out there having choked to death (and "found two week s later by hunters"). We bombed along the dirt road, and did a speedy balloon release. So far so good. And now, the moment of truth - we set up and turned on the SODAR (like radar but with sound). Power up, wait, wait, wait (repeat for many moments), and ... nothing. Fizzle. Sodar not working. Craig assuring us that it worked on campus.
This is the part about the bloody instruments not working! So we turned the thing on and off many, many times, as one does (right???), and finally Dais stood next to it and cooed something in its ear - and it turned on! Joy of joys!
OK so the sodar starts to ping happily away, one ping every 2 seconds I think. Meanwhile we are standing around yapping about weather, smoke, data etc. etc. When we realize there is dead silence, i.e., the sodar has died. More turning on and off, some gentle cursing, a great deal of sighing. And then, when all hope seemed lost, the dang thing burst into life again (ha! bet you thought it was gonna burst into flames!). And stayed alive!
So much joy this time that we ALL jumped into the vans and sped off to the tiny town of Valle, to partake in breakfast. The nice folks at the (only) restaurant managed to seat us, coffee us, and provide an excellent repast - thanks! Have you ever been in a restaurant and seen a group of 13 get seated and think "we'll never get our food now"? Well, we were that group of 13.
Back to the site. We ended up there from post-breakfast (8:45-ish) to noon, launching balloons to watch the development of the morning boundary layer. At some point the smoke had lifted and was now drifting to the northeast - the early low-level wind had been steadliy from the southeast before the low-level inversion mixed out.
We gave up after the noon balloon, and went back to town. Where some students fell into a coma for the afternoon :-)
Mike left (pre-arranged), so the story continues with just Craig and Alison in control. Dum-dee- dum-dum.

Weather records
Over the past few days, several weather records have been broken in Arizona. Unfortunately for us, all of them are in the wrong direction for generating convection.
With no moisture in the air to prevent heat loss, Flagstaff's overnight lows on Friday and Saturday night broke records. Saturday night's low (on Sunday morning) was 35o, breaking (shattering!) the old record (set in 1999) of 44o. In fact, as we gathered at 5am to do our sunrise balloon launch, my iPhone mentioned that it was 37o in Flagstaff AND in Barrow, Alaska. Brrr. Of course, nobody brought winter wear, so it was multiple tee shirt layers!
The previous night's low was also 35o, breaking the old record (1950) of 39o. Meanwhile down south, the Phoenix TV stations are reporting record-breaking low dew point temperatures. Unfortunately these are not archived by the NWS, but the numbers we're been seeing both in Flagstaff and in Phoenix are really low. Normally they would be in the 50's or better in the monsoon season. In fact, the record high dew point temperature for today (8/10/09) in Phoenix is reported as 73.9o. As I write this, Td in FLG is 23o. Rats!
Precipitation forecasting is pretty accurate in these conditions. Even I can do it! Forecast: zero.

Day 6 - analyzing data!
OK - we've been madly driving around getting all this data (balloon soundings and RAWS data), but haven't looked at it much! So today we are analyzing data. This has the side effect of NOT having to drive madly around all day! And maybe we can sneak in some pool time at the hotel.
The grad students were dispatched to download data from yesterday's RAWS site (and several undergrads volunteered to accompany them!) Meanwhile, the faculty dutifully hunched over their laptops engaged in the business of: developing tasks for the students ("look at sounding X and compute Y" etc.); developing questions for today's MIDTERM (YES - we ARE mean!!!); blogging (Alison); proposal writing (Craig); and keeping the department IT functions running remotely (Mike).
We're trying a different approach today. We're having the midterm from 4-5, and then the forecasting session from 5-6:30. And then dinner and a "free" evening - not ending at 10:30!
HOWEVER - tomorrow we plan a sunrise balloon launch back at the RAWS site. We will also set up the SODAR for the morning. The science goal is to watch the development of the boundary layer from sunrise (when we expect a shallow cool layer and inversion) to noon (by which time the boundary layer should have mixed up and developed). Bottom line is we gotta be wheels-rolling by about 5am - eeek! Hence - no late forecasting session today!

Day 5 - no clouds, plenty o' smoke
As you can see from the photo, we wound up on the rim of a famous canyon today, and Craig felt the need to hop down to a boulder for a photo opportunity. But that's near the end of the story...We started out with a plan to chase fires, since there were several lightning-started fires from yesterday's storms. We also wanted to set out a RAWS and leave it to get some solid data.
Everything fell into place somewhere northwest of FLG on national forest land (Kaibab). We ran through the smoke plume of a fire (supposedly "managed"). The unusually deep trough that passed through yesterday not only swept out every molecule of moisture from Arizona, but also produced strong winds (max gust at FLG today was 51 mph). As a result, the smoke plume was very well-confined to lower levels - interesting.
We then found a really nice spot to set up the RAWS. Off the road a bit, and in an open flat plateau region. Yesterday's fire-drill assembly of the RAWS (as a storm approached) was replaced by a more orderly set up today! We also launched a balloon. The RAWS spot was so perfect that we decided to leave the RAWS overnight!
So then, in our capacity of chasing fires - there being not one single cloud in the entire sky all day (well, OK - one small cirrus streak, but...) - we pushed north to look at another smoke plume we could see. And lo!! Suddenly there we were at the Grand Canyon. I truly believe I could come here every weekend and just sit and stare, and it wouldn't get old.
For some students it was the first look, for others the n-th, but we ALL enjoyed the views. Mike and Craig led a dash downhill, with most students in tow. I stayed behind to re
ad the story of an elite athlete who did the same - and died of dehydration. So there.After the excitement of the grand canyon, plus great views of a fire burning on the north rim, we hit a pizza place hard, devouring every crumb in site. For slow eaters like me, it's scary!
After a buzz past the RAWS site, we got back around 8:20 pm - and went straight back into class to work on verifying yesterday's forecast and discuss tomorrow's situation. Class ended at 10:30 pm - AGAIN!
Faculty are trashed!!!

Day 4 - we get rained on!
An early-ish start to the day, after more thoughtful staring at forecast maps and satellite imagery etc. We decided to head east and then south to the rim to intercept convection. Our plan was to set out the RAWS and - maybe - SODAR in the anticipated path of cells.
At Holbrook we turned south, after an extremely enlightening radio clip inviting us to visit Meteor Crater. "ALMOST two and a half miles in circumference". But not quite, I guess. Anyway, after the crater excitement, and nice views of the Painted Desert, we bombed south towards Snowflake and Show Low. Along the way, in an elevated flat plateau area with views for miles, we chanced upon a nicely developing storm, so we stopped to take about a million photos. The more we looked, the more we liked it. So , we drove away and then snuck back up on it while it wasn't looking. That technique worked well, as did the part about barreling down dirt roads at high speeds!
We got to spend some time parked under the path of several heavy rain shafts, complete with small hail (petite pea sized), and lightning/thunder. One strike happened while I was in the car (videotaping) and everybody else was outside UNTIL lightning hit REAL CLOSE. It was amazing and amusing to see how fast they all jumped back into the vehicles!!
One result of this episode was - dirty vehicles! As far as I'm concerned, this is a mandatory feature of a good road trip.
Lunch at McDonalds in Snowflake, followed by another thought session on which way to go next. Main problem was that very dry air was moving in steadily from the west, shutting down convection. Hence we bombed back north to I-40, and then east. Next problem - not too many (paved) roads in Arizona, which limited our options. So we stopped at the Petrified Forest National Park Visitor Center, and set up a RAWS and released balloons. A nice park ranger lady came out and said it was just fine to steal their data, and the head park ranger guy mentioned (sternly) that in future we should ask permission BEFORE setting up the RAWS :-)
Got back to the hotel at 6:45pm and headed to dinner. And now here we are at 10:05 pm STILL WORKING! Discussing tomorrow's forecast, and what happened today. Of course, with all this driving around and discussing, there's been no time to look at data!!!
At Holbrook we turned south, after an extremely enlightening radio clip inviting us to visit Meteor Crater. "ALMOST two and a half miles in circumference". But not quite, I guess. Anyway, after the crater excitement, and nice views of the Painted Desert, we bombed south towards Snowflake and Show Low. Along the way, in an elevated flat plateau area with views for miles, we chanced upon a nicely developing storm, so we stopped to take about a million photos. The more we looked, the more we liked it. So , we drove away and then snuck back up on it while it wasn't looking. That technique worked well, as did the part about barreling down dirt roads at high speeds!
We got to spend some time parked under the path of several heavy rain shafts, complete with small hail (petite pea sized), and lightning/thunder. One strike happened while I was in the car (videotaping) and everybody else was outside UNTIL lightning hit REAL CLOSE.

Day 3 - we hit weather
Day 3 (Wednesday) started with an early departure from Barstow (and a yummy hotel free breakfast).
Naturally, we just had to stop in Needles to experience the heat. It was 110 when we stopped - gasp! As we drove further into Arizona, we began to see some of the clouds we've been hoping to see - the ones associated with convection. By now, Mike Voss had the ThreatNet going, as well as radar etc. imagery on the laptop.
As we approached Flagstaff mid-afternoon, we decided to push on east and try to set up under or near a cell. We pulled off near a golf course, reasoning that there were plenty of trees and golfers to attract lightning! It worked! We got to see/hear lightning/thunder quite close. At one point Gina's hair was standing up on end. At which point we dove back into the vans :-)
We wound up about 25 miles east watching another cell come over. We launched our first balloon of the trip (yay!), and experienced more lightning. Things seemed to be happening to fast for RAWS etc. deployment.
To emphasize that this is a CLASS (3 units crammed into under 2 weeks), we had a longish class/forecasting session at night (8:30-10:30 pm). By the end, the giggles were rampant, but all the students got their forecasts in. Each student is required to forecast the values of 41 quantities on a daily basis as part of the course, and each night the forecasts are verified in the group discussion.
Tomorrow looks like the last good day for convection, so we are planning another early start and long day!

Day 2 - we set off!
The day started with the inevitable hiccup - lights on the trailer not working, but Craig solved that. To balance things out, Craig then made several emergency dashes back up to his office to get sunglasses etc., but we managed to leave at 12.
Blasted down I-5 and over the Tehachapi Pass to lovely Barstow for an overnight. There were some mid- and high-level clouds on the way down associated with some mid-level moisture - but really not much. We had mobile weather (using Baron's Threat Net), and could see some showers etc. firing up in AZ with the moisture surge. But the question is - will there be anything left by the time we get there???
Planning to leave EARLY and blast over to AZ - in time to catch any active weather!

Getting ready!
T-36 hours and counting!
The inaugural SJSU-Meteorology field trip gets started in 36 hours with an "in-class day", and then we leave for Flagstaff on Tuesday. We're heading there to practice our convection forecasting, and to do in-the-field observations. Hauling a bunch of meteorological instrumentation along.
I'm excited! I just hope the weather cooperates ...
