Title: Analysis of the Thermodynamics and Dynamics of Tropical Mesoscale Convective Systems
Abstract: The Tracked IMERG Mesoscale Precipitation Systems (TIMPS), combined with ERA5 reanalysis product and TRMM/GPM are used to identify the thermodynamic and dynamic controls that govern the progression and occurrence of mesoscale convective systems (MCSs). Composites are made of MCSs occurring broadly within the tropics (30ºS to 30ºN) during a period extending from 2000-2020, excluding those associated with tropical cyclones. The life of an MCS is divided into three stages: growth or initiation, propagation and maturity, and then eventual decay. The growth stage shows low level convergence and mid-level divergence. The divergence layer near 500 hPa is characterized by warm and dry anomalies, indicative of a stable layer that caps convection. The propagation and maturity stage is distinguished from the other two life cycle phases in exhibiting a cool and moist lower troposphere. Above this point, moisture and temperature anomalies are negligible. The third stage exhibits low level divergence and convergence in the mid-troposphere and further aloft at the tropopause, indicative of anvil remnants

Great work!!! Congratulations!!! I wish you guys had used a better microfone, so we (online audience) could listen better :) Maybe consider that for next presentation.
Here is (most) of Weather Watch, uploaded from the capture on the camera, since the live stream was having issues czcams.com/video/7I72WvPDrZo/video.html
Video is still cutting out at the :49 second mark.
Yes I know. I couldn't get it to work live. I did try to record to the camera itself, I'll try to upload that later today..
Thanks for the swing around to the chalk board - felt like I was back in class!
Correction on the avalanche danger situation, the weather service has just concurred that the danger has increased to warning levels. FWIW, the storm of record (March 2003) around here added 5"+ to the snowpack, and we did get the only avalanches that I can remember in Boulder Canyon (and near Eldora up the hill from there). PLUS: very informative section on the Polar Vortex - thanks! - Klaus Wolter
Two minutes in: You got the stats wrong about the Front Range snowstorm: the folks that got 36" or more (I had 46" out of 4.03" of moisture at 8.5K elevation, I live at the half-way point between Boulder and Longs Peak) had normal spring snow ratio (10:1 or higher). It is the lower elevation stations that had more rain mixed in to get the lower ratios, but never made it to 36" (nor 4" of moisture). Since the snowpack for the South Platte basin went from about the 90%ile to just over the 110%ile in this storm, and also added about 3" area-wide to the pack, I would not consider this much of an increase in avalanche danger either. My 2c from a 34-yr resident at this location (UW Madison, PhD '87)
Thank you for the clarification/correction, Klaus. I will pass it along to Patrick. Pete (BS '88, MS '92, UW-AOS Computer systems admin since 1995)
@@uw-aosuwmadison9381 No worries, Pete - here is the NWS writeup of the storm: www.weather.gov/bou/March_13_15_2024_Snowstorm
For folks that are wondering; The ultralight in the video is a Zigolo MG12. Chip Erwin's company, Aeromarine LSA, is an importer and distributor for them. The engine appears to be a Vittorazi Moster 185.
Bronze medal for the cold pool is still noteworthy. Good discussion and analysis.
😲👏👏👏👏👏 SI SEÑOR!!! BELLEZA DE AVION!
Glad to see the return of Weather Watch. Thanks as always for streaming this.
OH MY GOD! 😮 I was in the middle of this storm over in Southport near Dean Bozeman school! Looking at this from this perspective is just terrifying on its own! And I watched buildings and trees get absolutely destroyed! Damn! We are 850 strong!
GREAT job, Natasha!
احسنت
Congratulations Juliet! That was great.
Best CZcams video EVER
BORING! Imma watch Mr Beast
Excellent overview and perspective.
Weather Weenies Unite!! 🌭
Great to see the old Weather Watch crew back together. Sorry I can't be there in person.
Audio. Matters. Please.
Thanks Pete.
I remember this and remember how incredibly unlucky the coast was that it was actually strengthening as itade landfall
Better get some altitude or your chute will be useless. 😜
Forests make it possible for humans to LIVE period. Without Forests humans would become extinct,..period.

Looking for PhD defense for Bailey Murphy
Same!!

I'm so sorry, I forgot to update the go.wisc.edu link before the talk.. Bailey's PhD defense can be found at czcams.com/users/liveqhBLYVtNZao if you missed it live.
Congratulations Vijit. Your presentation was great!
It is literally a hole in the atmosphere. So all the air rush to it to fill the gap but because of the coriolis effect, the rushing air are being thrown out near the hole. So the hole is never filled. Normally this would cool off and the pressure woluld increase again because of the lower temperature. But the storm has to travel over a hot water surface which itself has hot air rising. So this is like an perfect engine.
Proud of you
Congratulations sreenad🎉
I would like to find out what it is motor ect
Good luck bro. We proud of you. Regards Ampuh Family from Bandung ❤
Good Luck 👍
😀Your presentation is very Cool, brother. Good Luck!
Semangat brothers 👍👍💪

Excellent Talk, Kudo's to all the members of the research team.
i have seen the footage of that
Can I have form?❤
Thanks Pete
Would it be possible to separate the cold pool analysis for North America from Eurasia? There are often very different seasonal evolutions in snow-cover for these two continents that *ought* to be relatable to the respective cold pool evolutions. In terms of predictability, I think it would be interesting to look at MONTHLY rather than SEASONAL precursor data (say, NOVEMBER vs DJF, or DECEMBER vs JFM), again, not just for the whole hemisphere, but split by continents (or even smaller scale). Thanks for stimulating my brain cells!
Sorry, Klaus, I just saw this today. I'll pass your question along to Jon and see what he says.
Nice to be able to watch these presentations almost the hour they are given. Is there any way to remove the date from the bottom right corner? It covers up information from the presentation. Thanx, Klaus
I'm a senior researcher at Heimkeeper Co., Ltd.Our company has an idea to reduce propeller noise and vibration of helicopters and drones.We're done with the experiment.We have applied for a utility model and a patent As a result of several experiments with small propellers, the current noise and vibration reduction effect is about 30%.Looking forward good news from you soon

Great discussion. It's been an incredibly mild January here in the lower Hudson Valley in New York.

Thank you.
I know I'm here late but I'm giving this vid thumbs down! What really annoys me is when the host doesn't respond to their followers! There's some good questions and the host can't even take time to touch the thumbs up button - let alone answer questions.
