• The Philippines is affected by these wind systems:A. Northeast monsoon – known as amihan.

- experienced from October to February.- brings cold mornings and heavy rainfall along the eastern coastal regions of the Philippines.

*Siberia & India → → → North Pacific Ocean

Ans:What turns this mass of cold air to the

right and passes over the Philippines?

cold air

B. Southwest monsoon – known as habagat

- experienced during June to September.

- brings heavy rainfall along the western

coastal areas of the Philippines.

C. Trade winds

- the prevailing winds in the tropics

- affect the Philippines whenever the

monsoon weakens during the rest of the

year.

c.1. South Pacific Trades bring humid weather in July

c.2. North Pacific Trades bring warm weather during April

and May.

1. calm winds near the equator. ___________

2. steady winds that blow toward the equator. ______

3. cool air that descends at about 30 degrees north and south of the equator because of the rising warm air at the equatorial region. __________

4. winds that are bent westward coming from the east and moving toward the subpolar regions.

Modified True or False.

1. Wind blows from a warm place to a cold place.

2. When warm air over the sea rises and the cooler

air over the land goes toward the sea this causes

land breeze during daytime.

3. The rotation of the earth affects wind

movement by deflecting the wind sidewise.

4. Trade winds is the deflection of the wind.
