Eye wall recycling phase?

Not an ERC. Just an incredibly intense CDO at the moment.

Impressive doughnut of very deep convection . Unlike earlier where the eye was clear and the convection was wrapped around in a spiral, now it looks like a solid doughnut. Would not be surprised if we wake up in the morning to an annular hurricane.

Interesting lumps on the periphery - they seem to be relatively long lived and only loosely connected with the CDO. Can be a consequence of very low lattitude?

Also, in the last 5 hours Ivan has been moving almost due W, not WNW as forecasted. Is this significant?

Have there been any landfalling hurricanes into SA?

It reminds me of Charley. You really have to look close to see the eye it's so small.

I don't see how that small of an eye can maintain that level of intensity. Seems like it has to go through an eye wall recycling soon.

An annular hurricane is a hurricane that develops an "annular" eye. The eye is rather pronounced compared to the windfield--it looks like a donut. Annular hurricanes are thought to be more stable and consistent in their intensity. They don't seem to go through eye wall recycling phases and they somehow manage to become very efficient. Were this to become an annular hurricane, it would therefore be far more likely to maintain its intensity longer. But less than 1% of Atlantic hurricanes actually become annular. Conditions have to be almost perfect for it to happen.

The word "annular" means "ring-like."

Just think of Isabel and you get what an annular hurricane looks like. Ahh, she was a beauty :)
