Impressive waves

#1 Postby txwatcher91 » Sun Feb 19, 2006 2:53 pm

I know that they are too far south to form anything tropical, but these waves look very impressive for this early in the season. This is not a good sign for 2006 hurricane season. The wave near 10W 5N almos t looks like it may have a little bit of spin to it.

In general, that is too close to the equator to spin. It is however some rather impressive convection for February, especially that far north.

I agree

however didnt a typhoon form right on the equator in 1998 or something?

Typhoon Vamei formed at latitude 1.5N in December 2001.

Typhoons can form at those low latitudes out in the western Pacific because while it is important to have some planetary vorticity, a low value of f can be offset if the background relative vorticity values are high enough. It has been shown that the western Pacific has some of the highest background relative vorticity values of anywhere in the world. Therefore, on occasion, it is possible to get tropical cyclones at low latitudes like that.

one in the indian ocean formed last year at .2N. If the relative vorticity is high enough, a TC could cross the equator
