Schools are not a business and a student is not a customer and this is the framing that encapsulates everything wrong with higher education. The “solution” of running universities like businesses rather than a public good was always the problem.

Annotating a long 3+ day loop of #Hurricane #Melissa from Kingston, #Jamaica radar. 2️⃣ periods appear where an eyewall replacement cycle, #ERC, looked underway. In both cases, inner eyewall stayed intact & outer bands merged, resulting in a larger eye & strengthening after. A remarkable evolution 🌀

I was worried for my crew mates when I saw them circling in the eye for over 20 mins. Looks like the very rough ride was confirmed. Plane had to leave early. They reported svr turb and a "sawtooth" eye. Looks like they moved 600-700ft up & down during this stretch in ~1 min.

This has probably already been posted here, but Melissa has displayed a classic mesovortex pattern that can be modeled in the simplest 2D atmospheric models ("nondivergent barotropic models"). Here's a comparison of this morning's VIS sat and Kossin and Schubert (2001) experiments.

Looking back at the rapid intensification of #Melissa, two things really stand out to me: 1) there were *5* consecutive six-hourly periods of RI 2) an RI period began when the storm was already at Category 4 intensity The red entries here highlight when an RI period began (30+ kt in 24 hr).

1-minute #GOES19/#GOESEast Visible and Infrared images with plots of GLM Flash Points showed prolific lightning activity within the inner eyewall of Category 5 Hurricane #Melissa as it approaches the SW coast of Jamaica. Low-altitude mesovortices persist within the eye.

The most recent recon data suggests that Melissa continues to intensify. Central pressure now down to 907 mb and a dropsonde released in the northeast eyewall measured a mean wind in the lower 150m of 185 knots (213 mph). This hurricane is truly in rarefied air as far as Atlantic hurricanes.
