🚨 New Study Alert!

Our study with @zmoon92.bsky.social & @edougherty.bsky.social offers new insights into how
African Easterly Waves (AEWs), the seeds of Atlantic hurricanes 🌀, are being shaped by a warmer, moister climate.

Just a reminder that NWS is considered essential during a government shutdown. Meteorologists will still go to work, forecasts will still be made, watches and warnings will be issued, data will flow. We won’t be paid until the shutdown ends, but we’ll still protect life and property as always.

It's not often we get a stratiform rain day like this! I'm quite enjoying it

🌍 The MMM lab at @ncar-ucar.bsky.social is running experimental realtime forecasts with a global 3.75-km MPAS model.

Goal: Highlight the power of global km-scale models for weather prediction from local to planetary scales, incl. tropical cyclones.

Leaving negative comments isn’t really helpful. It takes zero effort to be kind and just scroll past. I choose to remain hopeful and love what I do, because the people that matter most are the ones I took an oath to serve - the American public.

Funny, I was just looking at the Boulder forecast and wondering this. Feels really far out for a severe mention, but then again I’m a tropical guy…

Our research on the connection between African easterly waves (AEW) and ENSO was accepted! Using a wave tracker, we show that there is increased circulation, moisture, and convection around AEWs during La Niña, especially in the wave's mid- to low- levels near Africa. This may have TC implications.

I am especially proud of this work because of the contributions from Brooke Weiser, a former @miamirosenstiel.bsky.social undergraduate student who I had the honor of mentoring in research a few years ago. Our collaboration continued as I moved to @ncar-ucar.bsky.social and she started her career!

This paper also reflects an update to our easterly wave tracker, which now has been updated to work in the eastern Pacific. We also have produced tracks for both ERA5 and MERRA2. A climatology is shown below. The software is available as a python module (via pip). github.com/qlawton/QTrack

We believe these AEW changes are connected to shifts in regional circulation, including the African easterly jet and west African monsoon. While previous work has looked at ENSO and wave "activity", our use of a wave-tracker allowed us to directly quantify wave attributes and structure.

A quick heads up on some tropical weather social media posts you may see around this time of year. The GFS (U.S.) model is known to over-intensify storms in the western Caribbean and Gulf of Mexico in May and June. This means sometimes it will show a strong hurricane developing ~7+ days out,

1/

Dr. Levi Cowan on X
@TropicalTidbits

"The GFS commonly develops fictitious storms in the western Caribbean.

Typically, these arise from the aggregation of multiple small-scale vorticity perturbations (left panel) caused by and collocated with strong bursts of convection/precip (right panel).

While the GFS is not always wrong about the existence of these localized convective bursts, they are often way too strong, leading to small areas of intense vorticity/spin that eventually aggregate upscale into a tropical cyclone circulation, as we can see here on today's 12Z model run.

This is why the GFS is difficult to take seriously when it predicts TC formation, unless other models show a similar forecast. This is especially true in the western Caribbean, where the GFS has an extremely high false alarm rate.

Know your weather model before you trust its output!"
