Re: Eyewall Replacement Cycle

Clark posted a good explanation of this a while back (too much to wade through to find it). I am sure he will elaborate when he has time, or will correct me if I am misrepresenting what he said , But in summary, we know very little about eyewall replacement, we don't know exactly why it happens, and know very little as to the timing of when it happens, just that it does happen, mostly (but not always) with major hurricanes.




Thanks, Bill!

We have been talking alot about eyewalls on this board lately, but I didn't remember seeing anything specifically about timing of the replacement cycle and when peak intensity occurs in the cycle...

But I did manage to go back and find one of Clark's explanations from several months ago:

What is still unknown is the exact predictability of when one is going to occur as well as how fast they will occur and how far they will reach towards the center before resulting in the collapse of the original eyewall.




So I guess the answer is...
