华银铝厂厂区边界层温度层结特征分析

The Characteristic Analysis For The Temperature Level Knot Of Boundary Layer In Huayin Aluminum Factory District

利用华银铝厂探空实测资料对厂址区域边界层内的温度层结特征进行了分析。结果表明,厂址区域内污染物的扩散能力很强,600m高度以下11、14、17时三个时次没有逆温出现,且白天的垂直气温递减率很大,湍流交换强烈,有利于污染物的扩散;夜间一般都有贴地逆温出现,且强度较大,但其厚度较小。

This paper analyzes the characteristic of the temperature level knot of the boundary layer in the factory site by using the actual meteorological sounding data in Huayin Aluminum Factory. The result indicates that the pollutant diffusivity is very strong in the factory site, in 600 m altitude during the times 11 AM, 14 AM, 5 PM the inversion temperature gradient does not appear, and also the vertical temperature reducing-rate is very big in daytime and the turbulent exchange is intense, and is helpful for the pollutant proliferation; the inversion temperature gradient appears near ground in nighttime, and its intensity is relatively strong, but its thickness is relatively small.
