Re: Core is heating up and better organized

No problem, glad to explain to the best of my knowledge.
It shows temperature differences relative to its surroundings. (temp anomaly)
It is derived from GOES microwave sounder data and processed thru algorithms.
It basically shows temp anomalies as a function of elevation (vertical axis) and distance from the LLC (horizontal axis).
The center of the LLC is the left vertical axis.
The solid lines are iso-temps above the ambient and dashed lines are iso-temps below ambient.
You want to look for a warm core, i.e. solid lines at about the 8 to 14 kilometer level.
The graph currently is showing 1C above ambient core temp.
This is very moderate.
Most Atlantic canes will be at Cat 4 or 5 at a core temp of 4 to 6C.
Other cyclones respond to wind speed differently in different parts of the world.
I think the hottest I have seen is a 11 to 12C core temp in the Marianas.
Another thing to look for is the width of the core.
If the hottest temp is 300km or bigger, it is a very wide core and is slow to spin up.
This one looks normal and would seem to spin up like normal TC's
Finally, a well structured core has an inversion below the warm core, where temps are below ambient.
Hope that helps.
