In this class we are going to learn about the World distribution of Pressure Zones and the Planetary wind System/World Prevailing Winds
Answer Text: World distribution of Pressure Zones and the Planetary wind System/World Prevailing WindsThe Equatorial Low pressure Zone (ITCZ-low) • Found between 23 ½ ◦N and 23 ◦N• Experiences high temperatures. • A zone of low pressure and doldrums (light and intermediate winds). • Zone where S.E and N.E Trade Winds converge.• Associated with convectional rain and thunderstorms. • Migrates to the N and with the apparent movement of the overhead sun. The Sub-tropical High Pressure Zone• Found within 30◦N and 30◦S. • A zone of high pressure. • A region of calm descending air. • Source of Trade Winds and Westerlies.• Zone of divergence of T. Winds and Westerlies. The Temperate Low Pressure Zone • Found within 60◦N and 60◦S. • A low pressure zone.• Zone of convergence of westerlies and polar easterlies. The Polar High Pressure Zone• Found over the poles 90◦N and 90◦S. • A high pressure Zone. • Zone of descending calm air of low temperature. • Source of polar easterlies.
