垂直稳定度

提高对流天气临近预报准确率的关键问题之一是了解大气的垂直稳定度和垂直风切变。

To improve the accuracy of convection weather forecast , one of the key issues is to find out the atmospheric vertical stability and wind shear .

沙尘的辐射效应主要体现在冷却海表面而加热低对流层，因此沙尘有可能通过影响大气垂直稳定度从而影响海洋层云。

The main effect of them is to heat the lower troposphere , but cool the surface , so the presence of dust may cause a stabilizing effect on the temperature lapse rate , then affect the ocean low level stratus cover .

雾霾预报方程中的因子主要有水汽含量、全风速、垂直速度和稳定度指数等。

The top factors in the fog-haze forecasting equations are water vapor content , wind speed and stability index .
