Shifting more of my graphics work flow over to @blender.org - here's a first cut on the tropopause over North America. 🧪

Most simply, a storm is an area of rotating winds: a disk of vorticity. Strong hurricanes can develop more of a ring-like shape in vorticity, which can be unstable & develop mesovortices.

This is a basic process & can be simulated in a barotropic or shallow water model (here, with @visualpde.com).

The US must quickly move to aid in relief and recovery efforts in Jamaica: out of simple decency in the face of catastrophe, out of care for friends and family there, and out of our shared responsibility for supercharging these events through fossil fuel emissions.

Do tropical systems ever fully merge via the Fujiwhara effect? Here's a classic example from 2022 in the Indian Ocean: TC Vernon and Invest 93S.

Here's an interactive web simulation of the Fujiwhara effect, using @visualpde.com: lnkd.in/eaWCpKHF

When two areas of rotating fluid - like hurricanes in the atmosphere - get close enough, they can influence each other (the 'Fujiwhara effect'). Click to add your own vortices and see what they do.
