The Worlds Prevailing Winds
These are the major winds blowing over the earth frequently and consistently and which influence the world weather.
1. Trade Winds
• Blow from sub-tropical high pressure zone and blow to the equatorial low pressure belt.
2. Westerlies
• Originate from sub-tropical high pressure zone and blow to the temperate low pressure belt.
3. The Polar Easterlies
• Originate from polar high pressure zone and blow to temperate low pressure zone.
Monsoon Winds
• Seasonal winds which reverse in the direction of flow.
• They blow towards the land during summer (onshore) and from the land during winter (off shore).
• Bring heavy rains when onshore which can cause severe flooding.
• Well developed in the Indian Sun-continent, China, Japan and S.E Asia.
