MOVEMENTS OF AIR

Kris Ann Mae Y. Bonilla

Main Ideas 1.Warm air rises. 2.Air moves toward the place where warm air is rising.

3.Air moves from high-pressure areas to low-pressure areas.

4.Land heats up (and cools down) faster than water.

WHAT HAPPENS WHEN AIR IS HEATED?

What happens to the air in the surroundings as warm

air rises?

Warm air is risingAir moves toward the place where warm air is rising

What makes the air move?

When the sun heats up the earth, some places heat faster than the others. The air above the warmer places will also warm up and will rise as a result. The air in the surroundings will then move toward the place where warm air is rising. We call this moving air as wind.

Which warms up faster?

SEA BREEZE

Land Breeze

MONSOONS winds not rain; affecting large bodies of water and land that occur from

season to season

NORTHEAST MONSOON ( AMIHAN)COMES FROM THE NORTHEAST AND MOVES TOWARD SOUTH FROM

OCTOBER – MARCH

- DRY AND COLD (IT COMES FROM COLD AREAS SUCH AAS SIBERIA AND MONGOLIA, IN THE ASIAN CONTINENT)

SOUTHWEST MONSOON (HABAGAT)COMES FROM SOUHWEST AND MOVES

TOWARD NORTH.

FROM JULY TO SEPTEMBER

IT PASSES OVE THE INDIAN OCEAN AND COUTH CHINA

SEA BRINGING RAIN IN THE WEST OF THE COUNTRY

Low Pressure A low-pressure

area, low or depression, is a region where the 

atmospheric pressure is lower than that of surrounding

locations. The formation process of a low-pressure area is known

as cyclogenesis. Lows are usually associated with high winds, warm air, and atmospheric lifting. Because of this, lows normally produce clouds, precipitation, and other bad weather such as tropical storms and cyclones.

HIGH PRESSURE SYSTEM

or "high," is an area where the atmospheric pressure is greater than that of the surrounding area. In some places highs are referred to as anticyclones. These move clockwise in the northern hemisphere and counterclockwise in the southern due to theCoriolis Effect.

vice versa?
