Meteorology (Weather)/Coriolis


Iím training to be a Pilot and was told this.

It begins with the known fact:
If a high and a low pressure have the exact same isobar spacing, the high pressure system has stronger wind.
this is due to the Coriolis force.


Hope you can help it has me stumped, all else I know is that in  high pressure system there is also increased density and this would further increase the coriolis force which is acting in line with the anticyclonic behaviour of the high (southern hemisphere) and therefore increase the wind speed.


Hi Matt

The short answer is.... the Cyclostrophic force:
