Boing Boing: This website turns yesterday’s sky into a poetic memory. “What did the sky look like yesterday? A web project called What Color Was The Sky answers that for any location, using real atmospheric conditions to build a written and visual portrait of the sky.”

Gizmodo: Here’s Why Weather Forecasts Have Seemed So Inaccurate Lately. “Before the cuts, the NWS was launching weather balloons twice per day (once in the morning and once in the evening) from 100 locations. Today, the number of morning launches in the Lower 48 has been reduced by half, according to MyRadar senior meteorologist Matthew Cappucci.”

McGill University: Digitization of centuries of Canadian weather records promises to improve climate understanding. “Researchers have uncovered and digitized nearly two million 18th and 19th century weather observations from across Canada that offer new insights into how the country’s climate has changed over time. The international project draws on handwritten records dating from 1768 to […]

Mother Jones: Trump Cuts to Weather Data May Make Forecasts Less Reliable, Experts Warn. “As the United States prepares for hurricane season and a summer of record-breaking heat, experts fear the Trump administration’s cuts to climate and weather data programming could make the federal government’s weather forecasts less reliable when they are needed most.”

Saw this last Tuesday (2/24) while moored off Culebrita in the Spanish Virgin Islands. Photo is taken looking generally north, around 7:15PM local time. It was very bright, easily the brightest thing in the sky in that direction.
Our best guess: sunlight striking high altitude clouds from the SpaceX launch from Florida that evening.
Other (reasonable) theories welcome...

The view from central North Carolina.
Seriously, every single forecast for this alleged disaster has been wrong, at least where I live. We went from 2 foot snow totals in the forecast to maybe a quarter inch of ice, and it will likely all melt before Monday morning.
Has #Enshitification reached weather forecasting as well?

The University of Vermont (UVM) Water Resources Institute (WRI) is hiring a Senior Meteorlogical Technician to help establish a network of meteorological monitoring stations. This initiative aims to address critical gaps in weather observation identified by the National Weather Service and state partners.
The Senior Meteorological Technician will play a central role in this project, starting with the engagement of partners and the installation of a high-end prototype station. This position is ideal for a skilled technician eager to contribute to an impactful statewide weather monitoring initiative that will make the State of Vermont more resilient against flooding and other extreme weather events.

Ok... another napkin. 2/2
Federated #weather #meterology system.Per Station Data Points:
- Temperature, humidity, pressure: 3 points
- Wind speed/direction: 2 points
- Precipitation: 1 point
- Cloud camera (low-res sky photos): ~1MB per image
- Sampling rate: Every 5 minutes
- Daily data per station: ~300MB (mostly images)
- Total daily data: ~30PB (sic!)NWP Distributed Computing required;
- Grid resolution: 4km spacing (practical for regional)
- Vertical layers: 50
- Total grid points: ~6 million grid cells
- Computations per grid point: ~1000 operations
- Update frequency: Every 15 minutesDistributed Computing Model:
- Comparable to Folding@Home which peaks at ~2.4 exaFLOPS
- For 24hr forecast:
* Each client needs ~4GB RAM
* ~1 hour computation time per client per grid section
* Minimum active clients needed: ~50,000
* Network bandwidth per client: ~1GB/day
* Central coordination server: ~100TB storage, 40Gbps network
(That's beefy...but not "let's drain the rivers beefy") I just priced the NAS the other day. And the storage would cost maybe $8000. Which is a pittance. -
Ok... I'm using the other side of the Napkin. 1/2
Federated #weather #meterology system.Numerical Weather Prediction (NWP)
is the least resource intensive model.
- Divides atmosphere into 3D grid cells
- Solves fluid dynamics equations for each cellResolution/Scale trade-off:
- Global models: ~9-13km grid spacing
- Regional models: ~1-4km grid spacing
- Each halving of grid spacing requires ~8x more computing power 😑For continental USA you need about 1 station for 100km/sq or 53.51 hectopascals per imperial Troy tonne in freedom units.
For meaningful resolution.You need to abandon satellite data (unless it's free). There may be possibility to gather maritime weather data if this takes off.

#PSA
Getting out ahead of some #Misinformation...#Jews do not control the #weather.
There is no known device that can engage in "#CloudTheft" to cause #drought.
There is no "#JewMagic" controlling the #hurricanes to hit states where Harris is campaigning.
#Israel does not have a squad of pegasus ponies controlling the skies.
This is basic #meterology and #climatology, and is the very well understood and long-predicted result of #GlobalWarming / #ClimateChange, which is a fully-understood phenomenon, and was warned about in the 70s and 80s, where reports predicted the conditions we are seeing now at the time we are seeing them, well before any of the current people were in power.
There is no group controlling the weather, Jewish or otherwise. The people claiming that are using Jews as a #scapegoat, which is neither new nor based in any sort of reality.

Cool new tech for weather radar is coming using a phased array dual polarized radar system called Horus But the current Nexrad system's planned end of life isn't until 2040 so don't expect to see near real time images of storms for quite a few years yet.

My big question about this news is when this AI driven forecasting goes wrong how badly off the rails does it go? With weather we are seldom interested in averages - no one cares if it was 86F instead of 85F, it's all about nailing the outliers. So does it predict tornadoes when there aren't any, or fail to predict them when it should have?

It’s remarkable how the Met Office predicted the extreme weather from Storm Ciarán so far in advance. Before the low pressure system it developed from was anything special.
I highly recommend subscribing to the Met Office YouTube channel and watching their weekly Deep Dive and 10-Day Trend videos. I watch every video they put out 😊

It’s always amazed me how extreme the weather is on Mt Washington in New Hampshire. I learned about it in Julian May’s Galactic Milieu novels, wherein the mountain and the weather play parts in the plot.
This PBS Terra episode discusses it after covering the driest, wettest, hottest, and windiest places on Earth.

The Met Office forecast from Monday that there could be thunderstorms and localised heavy rain over Northern Ireland on Thursday was spot on.
Meteorology is a wonderful thing. My second favourite science after chemistry 😊

Yes, I've been wondering:
what are the real statistical chances for this happeninga) in the US South and
b) in California?
I hope we have some folks here you can calculate this statistically on a professional level. :)
