ABSTRACT. – Investigation of atmospheric humidity transport on the basis of aerological measurements. The global upper-air data base over the last 40 years is available by courtesy of College of Engineering and Applied Sciences at the University of Wyoming. Considering the fact, that in the atmospheric moisture transport between the oceans and the continents the humidity flow is much stronger towards the mainland than in the reverse direction, therefore it is reasonable to look for some correlation between the moisture transport and precipitation climate of the continents. For Europe, this is not easy because of the highly indented coastlines. According to laws of physics moisture transport influx to a (part of a) continent i.e. through the border of a closed curve occurs as rain falling out in the water balance of the geographical area investigated. We are interested in quasi-stationary temporal changes showed by the stationary approach mentioned above that can be related to climate change. In Europe the precipitation regime of the rainy coast in Western Balkans can be described as a stationary approach, while the relationship between the moisture coming from the seas and the precipitation climate of Central and Eastern Europe in the past 40 years can be examined as a quasi-stationary process. This change in our region moves towards more frequent droughts having great economic influences, mainly in agriculture and hydrology. The aim of this study is to analyse the relationship between moisture convergence calculated by the radiosonde measurements and the precipitation climate of a selected area of land.
