充分利用探空观测资料提高雾预报的时效
|
摘要
由于雾形成的时间较短,范围大小难以预料,通过对射阳2014年-2016年全部探空观测资料的对比分析以及平时的实践,发现有雾天气形成时,探空观测获得07时,19时数据中近地面层温度的逆差大小,等温的厚度和近低空温度、风的层结数据在雾生成时显示出一定的规律性,这些规律可以进行量化。在实践中,充分利用探空观测数据去预测雾浓度的大小,提供有效的预报效果。
Because fog is formed in a short time and the range is unpredictable, it is not certain whether there will be fog in the next morning. This paper reflected in 2014-2016 by comparison and analysis of all the sounding data and the usual practice, found the fog weather formed, sounding observations 07, 19 when the data in the surface layer temperature of gap size, the thickness of the isothermal and close to a low temperature, the stratification of the wind data generated in the fog shows certain regularity, these rules can be quantified. In practice, it has a good effect to predict the fog concentration by making full use of the observation data.
