Convection cell and breezes

1. Convection Cell
-Suppose air in an area is cool and under high pressure
-If a near by place is warmer and at a lower pressure
-The air will move from high pressure area to a low
pressure area .
This is called “Surface wind”

2. • What do you think can increase the intensity of the wind ?
• As the difference in pressure increases the wind intensity
increases
• Unequal heating and cooling of air results in difference in
pressure
• Where warm air will move
• Up and cold air moves down making a circular pattern of
rising and sinking air and wind called “Convection cell”

3. Sea Breeze

4. Land Breeze
