How Does The Rotation Of The Earth Affects the Wind System?

The wind is deflected or bends to the right in the Northern Hemisphere, and bends to the left in the Southern Hemisphere. There are three major sets of winds in the northern hemisphere: Polar easterlies, Prevailing westerlies , and northeast trade winds. The Southern Hemisphere have the same major sets of winds. The northeast and southeast trade winds converge in areas that lie between 30°N to 30°S of the equator. The area where the trade winds converge together is called the intertropical convergence zone (ITCZ). Thunderstorms and rains occur in the ITCZ because of the difference in temperature and pressure.

In the Philippines, cold winds from Siberia cool the air from December to February. In southern china and Mongolia, the weather becomes very cold that a high pressure area develops. Over the northern Pacific Ocean, Aleutian islands, and Australia, a low pressure area develops at same time the high pressure area in Siberia and Mongolia develops, the cold air from high pressure area moves toward the low pressure area.

The Coriolis effect diverts the cold air's direction and turns it to the right towards the philppines from the northeast direction. The cold moving air that passes over the Philippines is called northeast monsoon. The northeast monsoon is drawn towards the low pressure area over Australia.

The large air mass (Northeast monsoon), which starts in Siberia, chills in the Philippines from December to January. It eventually goes down to Australia. The wind system is known amihan by Filipinos.

From March to may, the Philippines temperature is at its highest, warm air rises over the country as a result. Habagat (southeast monsoon) visits the country from June to November. The southwest monsoon brings much rain starting the rice planting season.
