Avijit’s late night thoughts

Late night thoughts from Avijit Gangopadhyay:

Hi Oscar:

I was reading through your blog of this evening and was intrigued by the Glider current map...

Then I was looking at the model out at our site http://www.smast.umassd.edu/modeling/RTF/MARCOOS/M_Nov02_09_vel_temp25.php
and was trying to see what the model is showing at that location for today and next couple of days. You can go frame by frame or run
a quick animation...

What struck me is that the model is showing a variable pattern of shelf eddies interacting with each other making the currents go in different directions depending on which side of an eddy (of which kind) and the front you are on... It is quite variable near the Glider location around
73.5W, 39.2W. To begin with there were two shelf eddies opposing each other to the east of the Glider location, and then new eddy-like
formations are happening..

I have not checked the other models yet (its late now), maybe they show similar things even better resolved. Ours is pretty coarse resolution.

I am copying Wendell who can also take a look and let me know what you think... Its interesting nonetheless...

You can go to our site www.smast.umassd.edu/modeling/RTF/MARCOOS and then choose Mid-Atlantic shelf zoom and browse through the recent forecast...

Good night!

Avijit.
