rise:sink
Numerical models use equations based on laws of physics that are calculated at
grid points
Pressure gradient does:
causes the wind to blow, is stronger where isobars are closer together, and is stronger where height lines are closer together at 500 mb

pressure
Why are upper level winds strongest int the middle latitudes.
uppeer level pressure surface have the steepest slope in middle latitudes.
On the surface map, winds tend to blow
at a slight angle across isobars from high to low pressure
Pressure gradient force can be described as all the following except:
does not cause the winds to turn to the right in the Northern hemisphere.
