摘要
对2005年6月2日至3日出现在黄海海域的大气波导的产生、维持、消亡进行了分析,认为此次大气波导的产生主要是由于海表水温低于气温,且近地面层受低压前部及南部的影响,湿度大,高空受低压槽后部的影响空气干燥,导致湿度突降层出现而产生了大气波导,此后由于低空没有明显的天气形势影响,低空湿度依然很大,高空仍由低压槽后部控制,使大气波导得以维持,当高空受低压槽槽线控制时大气波导逐渐消亡。
The production, maintenance and dieing down of the atmospheric duct near the Yellow Sea area from June 2 to 2 in 2005 is analyzed. This atmospheric duct production mainly depends on that the sea skin temperature is slower than air temperature, and near surface is influenced by the frontpart and south part of low pressure. The humidity is big, and low pressure retral zone results in the dryness upper air, the suddenly falling of humidity. Hereafter as a result of not obvious synoptic situation influence, the low altitude humidity was still big, and the upper air still is controlled by the low pressure retral zone, so the atmospheric duct maintains. When the upper air is controlled by low pressure trough line, the atmospheric wave guide gradually witheredaway.
