本文利用 1个考虑了地形效应、植被影响、长波辐射、地表能量收支、液态水的重力沉降等影响雾的形成和发展主要因子的三维海雾模式 ,模拟了 1995 - 0 6 - 0 1发生在黄海的 1次实际海雾过程 ,分析了海雾生长、发展和消亡过程中液态水含量和其它物理量的三维时空分布变化特征。结果表明 ,该模式能较好地模拟出黄海海域实际的海雾生消过程 ,对海雾的三维结构有一定的模拟能力。

In this paper, a three-dimensional sea fog model, in which the topographic and vegetatve effects, long-wave radiation, surface energy budget as well as the liquid water content gravitational sediment of fog droplets are considered, is employed to simulate a real sea fog event on June 1, 1995 over the Yellow Sea. The three-dimensional characteristics of the liquid water content and other factors during the formation, development and dissipation stages of sea fog are discussed. It shows that the model simulates the evolutionary process of a real sea fog event over the Yellow Sea well. The present model is capable of simulating the three-dimensional structure of sea fog.=
