纵观近年高考,在大气这个专题里,对降水影响因素的考查所占比例非常高,那我们就需要详细地了解降水的影响因素。一、降水的影响因素影响降水的因素主要包括:大气环流:气流上升易降水,如赤道低气压带;气流下沉降水少,如副热带高气压带;风由较低纬度吹向较高纬度易降水,如西风带;风由海洋吹向陆地易降水,如夏季风。海陆位置:沿海受海洋暖湿气流影响的地区降水多,内陆降水少。地形:迎风坡降水多,背风坡降水少。
Looking at the recent college entrance examination, in the atmosphere this topic, the examination of the factors affecting precipitation is very high, then we need to understand in detail the factors affecting precipitation. I. Factors Affecting Precipitation The factors affecting precipitation mainly include: atmospheric circulation: rising air flow and easy precipitation, such as the equatorial low pressure zone; less precipitation under the air flow, such as the subtropical high pressure zone; wind blowing from lower latitudes to higher latitudes Precipitation, such as the westerly winds; winds blowing from the sea to the land, such as the summer monsoon. Sea and land locations: The coastal areas affected by the warm, wet air of the oceans have more precipitation and less inland rainfall. Topography: There is more precipitation on the windward slope and less rainfall on the leeward slope.
