: Winds over equatorial regions two spheres up change direction every 12-14
months (east-west).

I altavista'd QBO but wasn't able to find specifics.

* Which way are the winds blowing right now?

* When are they expected to change next?

* I remember a newspaper article stating that when they change, they
momentarily stop; and that increase sun exposure probs may occur then. Is
this commonly accepted.

This new science brings up global warming and is as controversial as the
latter. So I don't want to get into that frankly; start another thread if
you do.

Take a look at

The bottom graph will show you the recent state. IIRC wind towards
the east is positive. It looks like the direction switched around the
beginning of the year, depending on what altitude you want to reference.


In the sense that the east-west component goes through zero, yes.

Not that I know of, but I'm not a QBO expert.
