Re: Convection doing its job - getting a good broad core warm up

It shows the difference in temperature vertically and horizontally relative to its surroundings.

Vertical scale is vertical height in the atmosphere with the ocean surface being at the bottom.

Horizontal scale is the hoizontal distance away from the LLC.

The left end of the graph is the estimated LLC Center.

The lines in the graph are isotherms.

Solid means they are warmer than the surroundings and dotted means they are cooler than the surroundings.

A TC has a warm core that exists from about 8 to 12 km vertically above the ocean surface.

Right now you are seeing a 0.5C core that exists between 9 and 12 km altitude with a radius of about 450km about the LLC.

This is very broad.  Most cores are around 150 to 250 km radius.

As more convection fires, latent heat releases in the mid and upper levels which warms the core up.

A strengthening TC will have increases in core temperature.

It is not uncommon in the Atlantic to have a Cat 5 with a 4 or 5C core.

In other basins I have seen cores up to 11 to 12C.
