The WPAC is Cookin'

[wxmann_91]

Loop I made from Calamity's files:

I would've put this in the Saomai or the new Invest thread Matt made, but I did want to point out some things:


1) I did not see this being brought up. Notice how at the beginning, Bopha is west-northwest of Saomai. Near the end of the loop, Bopha is southwest of Saomai. Classic example of Fujiwara.

From Wikipedia article on Fujiwara: "When the two vortices are of unequal size, the larger vortex will tend to dominate the interaction, and the smaller vortex will orbit around it."

Note that Bopha almost orbits around Saomai. In fact, at the end of the loop, Bopha loses its convection, but if this was Vis, you would see the naked LLC meander to the south of Saomai. Of course, now that Bopha's dead, the Fujiwara interaction is gone as well. But, something interesting I wanted to share.


2) Notice that overactive monsoonal trough. Great latitude (10-15N) to spin up a typhoon or two. (In fact once three TC's were spun up in one day, all from the same monsoonal trough.) Wet MJO is sure doing its work there.

It must be hell to sail through that region

[Hybridstorm_November2001]

Right now, no doubt it is. The worst region for sailing however is between Africa, South America, Australia, and Antarctica the so called Southern Ocean; the legendary furious fifties and screaming sixties. The wind literally never stops blowing, and the waves never stop crashing. That is why the Vendee Global single handed race is considered the most dangerous in the World, and with good reason to, most entries never even reach the finish line in France.

I see three area's along the monsoon trough that are very interesting.

1# At 15 north/128 west...This system looks very good.

2# At 15/18 north/140 west best of them all but has a trough to the north. So some shear.

3# 15 north/148 west which the JTWC thinks fair right now.

We will see how many of these form.
