A convection cell forms when warm air rises from areas of low pressure and cooler air sinks into areas of high pressure, creating a circular pattern. The difference in air pressure and temperature between regions drives surface winds, with wind intensity increasing as pressure differences grow. Unequal heating and cooling of air is what results in these pressure differences, causing warm air to rise and cold air to sink in a convection cell.

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”
