THE INFLUENCE OF ABSOLUTE THERMAL INVERSION ON THE RELATIVE HUMIDITY IN THE LOWER TROPOSPHERE

ABSTRACT: Increasing temperature values in altitude, as a deviation from normal law, generates stability of air masses. The most typical situations occur outside the Carpathian chain. In particular cases, when the maximum barometric prevail on large European territories, absolute thermal inversions occur, which are characterized by large thickness, intensity, duration and amplitude. These types of thermal inversions block water vapour at lower levels and produce changes in atmospheric moisture regime by forming mists and low stratiform clouds. Geostatistical analysis of this climatic risk phenomena for aeronautical activity was carried out by processing temperature and moisture database from 7 aerological stations and analysis of synoptic maps. The results revealed a strong connection between the two meteorological phenomena, with the highest frequency in winter.
