Document Summary
Atmospheric pressure: barometric pressure, is the weight of a column of air at a point on or a(cid:271)o(cid:448)e earth(cid:859)s surfa(cid:272)e. force exerted by gas molecules on a surface. Convergence: air flows horizontally from areas of high pressure to areas of low. Divergence: flow of air out of a region and is accompanied by a reduction in atmospheric pressure. The rising warm air creates clouds and heavy precipitation. Front: meteorologists refer to the boundary between cool and warm air masses. Cold front: forms when cool air moves into a mass of warm air; a stationary front has a boundary that does not move much. Storm: typically develops when a fast-moving cold front encounter a slow-moving warm front. Occluded front: as storm intensifies, the cold front may overtake the warm front and meet another cool air mass. Thunderstorms: most of them are in equatorial regions. The city of kampala, uganda, near the equator in east africa, thunderstorms nearly 7/10 on average.
