Hi,

Pretty basic question. I am looking for information about predicting wind
direction. That is, what do you need to know, and how do you make
predictions about the direction of the wind, say, in a 2-3 day period ahead.
I've looked in a few books and a few weather sites, but not really seen
anything that is direct and basic.

Thanks,

BK

Buys-Ballots law:

In the northern hemisphere, if one stands with one's back to the wind,
low pressure is on one's left and hight pressure on one's right. These.
.. . are reversed in the southern hemisphere.

That should start you off. Knowing how prevailing winds work in your
area will tell you what to expect as will synoptic charts and forecasts
portraying the positions of coming highs and lows.

Thank you. That opens some doors, so to speak. At first the rule sounds
strange, but I see the coriolis effect makes the air moving from high to low
take a right turn. As a follow-up, could you tell me a good site for seeing
the highs and lows as they may affect several days of weather. I live in
the Atlanta area. I would appreciate it.

I can't help you there. Try Weather Underground or The Weather Channel.

This is a good one for the north east Atlantic:

Perhaps you might be able to explain how the Coriolis effects operate
on the severe gales we get at 60 degrees north the same way as it is
supposed to affect the severe gales you might get.

Bear in mind the general direction that ours take, compared to yours.
