Document Summary
Large scale circulations-monsoon: monsoon: a wind system that exhibits a pronounced seasonal reversal in direction. In winter, the cold air over siberia creates a high-pressure region. The clockwise flow out of the high causes air to flow out over the indian ocean and south china sea. This results in dry conditions over the land. In summer, the warm air over the continent creates a low-pressure region. The counterclockwise flow into the low brings warm, moist air from the ocean to the continent. This results in wet conditions over the land. Global circulation: general circulation: the long term average of the global winds, factors that drive the general circulation. Polar to equator differences in radiation budget. Doldrums: the equatorial belt of calms or light variable winds lying between the two trade-winds. Subtropical highs (horse latitudes): a belt of calms or light variable winds and subsiding air located near the center of the subtropical high.
