METHODS FOR DETECTION OF TORNADOES IN POLAND (CASE STUDY)

Joanna POPLAWSKA, Katarzyna GRABOWSKA

Abstract


The purpose of this paper is to specify potential meteorological conditions characteristic for a day (14th July 2012) when dangerous whirlwinds occured in Poland, as well as to evaluate the possibility to detect them by means of available methods and devices. Based on ESWD reports, a set of tornado-type occurrences was selected. Several radar products were analysed in time intervals of 10 minutes. The following parameters were considered: maximum values of reflectivity, vertical wind profile, as well as echo height. Based on satellite images the altitude of storm cloud tops was defined. The data concerning radar products comes from the Institute of Meteorology and Water Management. The satellite images were acquired from the website. Additionally, vertical aerological soundings and synoptic maps were used. In order to analyse thermodynamic instability, convective indices were calculated.
