Verification of indirect methods used to define the precipitation phase
Abstract
The purpose of study is verification of three indirect methods used to define of the phase precipitation. There methods are based on empirical data of thermal conditions in the vertical profile and surface layer of troposphere. Three methods can be used to forecast of precipitation phase. Verification of selected methods was based on statistic attempt counting the 400 data. To define the precipitation phase in the methods there were used data from aerological station Legionowo and meteorological station Warszawa–Bielany. The same control was executed on the basis of data coming from reanalysis. Consistency of precipitation phase with criteria used in the selected methods is slightly weaker in case of data that come from reanalysis than in case of using data from aerological soundings. The consistency of indirect methods reached in case of rainfall up to 86% of cases, and in case of snow up to 99%.
