Hurricane Irene Banter Thread


Recommended Posts

To give the scientific explanation: You've got land friction and the TC storm motion negating the effects of the winds in the left side. Storm motion negates some of the wind (if the storm is moving at 10 mph the left side will effectively have 10 mph weaker winds) and land friction can reduce wind speeds dramatically.

To give the nonscientific explanation: Earl was totally loltastic.

Just wondering if there are any Dominican Republic radars available for looking at...I have the Puerto Rico one up, but would love the other one too...also the GOES link that has trop plots you can click on...my old link doesn't work anymore for some reason. Thanks again...no more asking for awhile! :rolleyes:

Most research has shown that the asymmetry is actually about half the translation speed. In your example, it would mean winds on the left hand side would be about 5 mph less. That assumes a symmetric storm, though. With ET storms, it's completely different as the temperature gradient forces the strongest winds ahead of the developing cold front in the WAA zone where the mixing is strongest.

Checked.. You can go to their site HERE and there is a section for radar but it says it's "Not Available". The site is a pretty good resource anyway if you can navigate Spanish (My Google toolbar does it automatically.)

And the GOES Imagery (floaters are at top): http://www.ssd.noaa.gov/PS/TROP/trop-atl.html

That's what I was getting too.....Thanks for the Imagery! Appreciate it very much.

Thanks for the clarification... and I was assuming a symmetric storm for this particular situation.

For the DC-NYC corridor, especially those along the Chesapeake Bay, if I remember right Isabel west just to the west of DC right? To limit the risk of water being pushed up the bay causing flooding, we'd want the eye to travel over the Bay or to the east of it right? As anyone that lived here during that one remembers it wasn't the winds or the rain that were the big issue, it was the push of water up the bay that caused the flooding which was a nightmare for some.
