Abstract

The statistical characteristics are computed for the number of cloud layers based on radiosonde data from 965 aerological stations located at different latitudes of the globe for the period of 1964–2017 and on the CE method for the determination of cloud boundaries and cloud amount from the temperature and humidity profiles retrieved from radiosonde data. The calculations are performed for the atmospheric layer from the surface to the height of 10 km. The geographic distribution of seasonal and annual mean values as well as of standard deviations is obtained for the number of cloud layers. The amplitude of their regional variations is determined, that allowed specifying the spatiotemporal features of atmospheric layering into cloud and intercloud layers. The results agree with data of aircraft-based sounding, radar data, radiosonde data, and the results obtained from free balloon experiments.

1964-2017年不同纬度地区无线电探空仪数据的云层数的长期估计

摘要

根据1964-2017年期间位于全球不同纬度的965个气象站的无线电探空仪数据，以及根据温度确定云边界和云量的CE方法，计算云层的统计特征和探空资料从探空仪数据中检索。对从地面到10 km高度的大气层进行计算。对于云层的数量，可以获得季节平均值和年度平均值以及标准偏差的地理分布。确定其区域变化的幅度，从而可以指定将大气层分为云层和云间层的时空特征。结果与基于飞机的探测数据，雷达数据，探空仪数据，
