So who's right?
Given the size of the ladle used for the calculations, I find that an 6 report in the estimates is very reasonable : Cheesy:

The question was asked at NOAA (hurricane division) which gives a wind power of 1,5 TW and a thermal power of 600 TW :!:

It's true you're right, 6 as an error report in meteorology is "acceptable" ... since for decades the weather reports were so false anyway : Cheesy: : Cheesy:

Well the report 1.5 / 600, thank you because it is a good order of magnitude to have in mind: there is 400 times more thermal energy than wind energy in a hurricane... I imagine that a simple storm must be in the same proportions?

So hang in there because the Accumulated cyclone energy (ACE) unit is 10 ^ 4 (nautical nodes) ²!
