Severe Weather Environments in Central Europe as characterized by proximity soundings (original) (raw)

2014

Abstract

We have performed a study of environmental conditions related to severe convective weather using proximity soundings across central Europe, which, to our knowledge is the largest that has been carried out in Europe to date. Our study was done with forecasters in mind and our aim to help them to assess the risk of particular types of severe weather individually (hail, wind gusts, excessive precipitation, and tornadoes). The full study consists of an analysis of several environmental parameters (indices) and their ability to discriminate between no severe, severe and extremely severe categories that we defined for each severe weather type. The severe weather reports were obtained from ESSL's European Severe Weather Database. The parameters (indices) were calculated from 1962 proximity soundings that were associated with at least two lightning detections by the EUCLID network, acquired for 4 years of thunderstorm activity (2008-2011). Our preliminary results include the following: ...
