Sea breezes link temperature, density, and pressure. The land and sea warm and cool differently, creating a small circulation that may change between day and night. Larger weather systems can strengthen, weaken, or prevent that breeze, so temperature differences alone do not predict a place's actual wind.

air pressure
The force air exerts on each unit of area.
pressure gradient
How rapidly pressure changes across a distance.
sea breeze
A local wind moving from water toward warmer land.

The interactive activity is loading.
Simplified pressure-force model; actual winds also respond to rotation and friction.
What to look for
- The difference between high and low pressure
- The direction of the pressure-force arrow
- Surface flow and the return flow above it
Explain what you noticed
Which way does the pressure-gradient force act?
Keep this idea: Pressure differences drive wind, while rotation, friction, and local heating help shape its movement.
