you're not using a client that supports colored tables and have tried
to compensate. Low graphics mode looks much better on clients that
do... we recommend switching to Netscape 3.0 or Microsoft Internet
Pressure Gradient Force
directed from high to low pressure
The change in pressure
measured across a given distance is
called a "pressure gradient".
The pressure gradient results in a net force that is directed from
pressure and this force is called the "pressure gradient force".

The pressure gradient force is responsible for
triggering the initial movement of air.
