Global Winds and The Jet Streams How do global winds and the jet stream influence weather and climatic conditions?

Global Winds Global winds are found in each convection region. Global winds are found in each convection region. Tropical 0°-30° North or South of the equator.Tropical 0°-30° North or South of the equator. Temperate 30°-60° North or South of the equator.Temperate 30°-60° North or South of the equator. Polar 60°-90° North or South of the equator (to the North or South Poles).Polar 60°-90° North or South of the equator (to the North or South Poles).

Global Winds The Trade Winds blow from East to West in the Tropical Region; moving warm tropical air in that climate zone. The Trade Winds blow from East to West in the Tropical Region; moving warm tropical air in that climate zone. WE

Global Winds The Prevailing Westerly Winds blow from west to east in the Temperate Region. The Prevailing Westerly Winds blow from west to east in the Temperate Region. WE

Global Winds The Temperate Zone temperatures are affected most by the changing seasons, but since the Westerly Wind Belt is in that region, the weather systems during any season move from west to east. The Temperate Zone temperatures are affected most by the changing seasons, but since the Westerly Wind Belt is in that region, the weather systems during any season move from west to east. W E

Global Winds Since the United States is in the Westerly Wind Belt, the weather systems move across the country from West to East. Since the United States is in the Westerly Wind Belt, the weather systems move across the country from West to East. WE

Global Winds Tropical weather systems, for example hurricanes, are moved in the prevailing direction of the Trade Winds. If they enter the Westerly Wind Belt, they are often turned, and move in that direction of the prevailing wind.

If they enter the Westerly Wind Belt, they are often turned, and move in that direction of the prevailing wind. Start: W E Change: W E

Global Winds The Polar Winds blow Northeast to West in the Polar Region moving cold polar air in that climate zone from the poles toward the West. The Polar Winds blow Northeast to West in the Polar Region moving cold polar air in that climate zone from the poles toward the West. NE W

Jet Stream The Jet Stream is a fast-moving ribbon of air that moves from West to East in the Northern Hemisphere around the Earth. The Jet Stream is a fast-moving ribbon of air that moves from West to East in the Northern Hemisphere around the Earth. It dips and bends and Constantly changes positions. It dips and bends and Constantly changes positions. W E

Jet Stream As these changes occur, air masses and weather systems in its path are moved along by the fast moving air. As these changes occur, air masses and weather systems in its path are moved along by the fast moving air. W E
