Default Can someone explain pressure?

The greater the difference, the stronger the wind. The
coriolis effect and the rotation of the earth make the wind blow
counterclockwise around a low pressure area, and clockwise around a high
pressure area (Northern Hemisphere).

A lower central pressure would mean a bigger pressure gradient, and
therefore stronger winds and a "more intense" storm. There is more to it,
but I tried to keep it simple.


I can't thank you enough!!!!


You shouldn't thank him at all. Any appeal to the coriolis effect turns
such an explanation into a fairy tale.

An excusable dumbing down I suppose. The cyclone system does seem to
follow the axiom in the tropics and sub tropics.

It falls on its head for the hurricanes and storms that come east from
Canada. It is still born if you consider that the effect is not noted in
the southern Atlantic. Winds are stronger there but not contained in
ocean basins.

Cyclonic activity in the south Atlantic is remarkable for its rarity.
