Answer:
Explanation:
We measure air pressure in hectopascals.
Lines joining places of equal pressure are known as
isobars.
The difference in pressure between two places is known as
the pressure gradient force.
Winds always blow from a high pressure to low
pressure.
The isobaric interval on in the sketch is four
hectopascals.
Air that subsides on the surface of the earth creates a
high pressure, and so convergence takes
place.
