Overview

Atmospheric pressure, wind, pressure belts, air masses, fronts, and storms together explain how the atmosphere moves and how weather changes. Unequal heating of Earth creates pressure differences, and air moves from high pressure to low pressure. Near the surface, wind is shaped by pressure gradient

Key Concepts

Atmospheric pressure is the weight

Atmospheric pressure is the weight of a column of air from mean sea level to the top of the atmosphere, expressed in millibar. The average sea-level p

Isobars are lines connecting places having

Isobars are lines connecting places having equal pressure. Closely spaced isobars show a strong pressure gradient, while widely spaced isobars show a

This force is produced by differences

This force is produced by differences in atmospheric pressure. It acts perpendicular to isobars and pushes air from high pressure to low pressure. It

Coriolis force is caused by Earth’s

Coriolis force is caused by Earth’s rotation. It deflects wind to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. It

When pressure gradient force is balanced

When pressure gradient force is balanced by Coriolis force, and isobars are straight with no friction, wind flows parallel to isobars. This is called

Learning Objectives
