ABSTRACT. Hazardous extreme weather phenomena with impact on transport systems in Dolj Country, Romania. Fog, glazed frost, hail, blizzards, snow cover and strong winds are recognized as some of the most representative climate hazards impacting transport systems. The authors computed several climate indicators based on their cumulated frequency (average annual number of days) in order to highlight the most significant hazardous phenomena using the climate database (1961-2010) of the most relevant weather stations in Dolj County and its surroundings. The indicators were computed and integrated in GIS using spatial analysis techniques resulting the regionalization of extreme weather phenomena. Also, ranking the analysed phenomena according to their importance in impacting the transport systems, a multiple climate hazard (MCH) map have resulted. The derived values were classified into three intervals corresponding to three intensity classes: high, medium and low. In order to spatially quantify the MCH, the share of each intensity class at administrative-territorial units (LAU2) was calculated.

Keywords: extreme weather phenomena, transport systems, multiple climate hazard (MCH), Dolj County, Romania.
