After a devastating landfall in Jamaica, Major Hurricane #Melissa has emerged north of the island. In a few hours it will strike again, this time in southern Cuba.

It looks to me like Melissa is taking a few steps back so it can get a running start at Jamaica.

And the wind penetrated into the walls of our apartment building, popping the drywall open from the inside out.

As of October 20, water in excess of 30°C extended 60 meters below Tropical Storm Melissa.

A slow-moving storm will upwell water (bring deeper water up to the surface) because its winds are actively pushing surface water away, but these Argo float observations show that deeper water is also warm!

I see inner core non-propagating waves, outer core non-propagating waves, and transverse bands too.

I'd like to thank Andy Dessler from Texas A&M for leading the response to the DOE climate report, and for letting me participate!

I did it a few times with the drugs. Then I tried it without the drugs, and it did not go well.

Thanks!

Professor Emeritus Wayne Schubert received the Carl-Gustav Rossby Research Medal from the @ametsoc.org. It represents the highest award the society can bestow upon an atmospheric scientist.

Congrats to all the awardees on receiving 2026 recognitions!

Sorry, I mean the last 3 or 5 years!

Is this year worse or better so far?

Dave Nolan @davenolan305.bsky.social · Aug 27

James, any chance you can make that plot again with the average OFCL errors too?
