摘要
根据大气边界层理论中Monin-Obukov相似理论,对影响蒸发波导的不同气象要素进行了分析研究。结果发现:中国南海西沙海域海区蒸发波导出现的概率,一般早上出现的概率较高,中午较低;冬季出现概率较高,夏季较低。而中国南海西沙海域海区蒸发波导的高度在其他气象要素条件一定的情况下随月份变化、大气湿度、气海温差、水平风速等的变化有一定的敏感性,大气湿度对蒸发波导高度的影响较大,水平风速影响较小。
According to the similarity theory Monin-Obukov of the atmospheric boundary layer theory, the different meteorological elements affecting evaporation ducts were analyzed. The results showed that： the evaporation ducts probability of the China Xisha Sea, generally is higher in the morning, and lower in noon; The probability is higher in winter, and lower in summer. The evaporation ducts heights of the China Xisha sea in other meteorological conditions in certain circumstances have a certain sensitivity depending on the month, atmospheric humidity, air sea temperature, and wind speed, and the affect of the atmospheric humidity is largei＇, wind speed is less.
