摘要
用WRF中尺度模式对2014年4月8—11日发生的一次黄海春季海雾进行数值模拟,结果表明:在海雾生成前期,低层空气温度高于海洋表面温度;在海雾发展过程中,雾顶的辐射冷却作用通过湍流活动可以影响更低层的海雾,低层空气温度降低,海雾覆盖区域气温低于海温,并且雾顶越低,低层大气降温越明显。同时,适当的湍流活动有助于海雾形成。
The WRF model was employed to conduct the numerical simulation to analyze a spring sea fog event over the Yellow Sea which occurred on 8th-11th April, 2014.The results were as follows：at the early stage of the sea fog formation, the lower air temperature was higher than SST, and then because the radiation cooling effect on the top of the sea fog could influence the lower fog through the turbulence ,the lower air temperature was reduced which resulted in SST higher than the lower air temperature.The top height of sea fog was lower,the lower air temperature was reduced more obviously.In addition ,the appropriate turbulence contributed to sea fog formation.
