SEVERE CONVECTIVE WIND IN NORTH-WESTERN ROMANIA
ABSTRACT. –The present paper aims a comparative analysis of the cases when the convective wind gusts reached and exceeded 25 m/s in the warm season (April-September) of the years 2012-2017. In the range studied were identified 6 cases: 2 cases in 2012, one case in 2015, and 3 cases in 2017. The 90 km/h limit registers on level 10 on the Beaufort scale, which may cause uprooting trees and affecting the structure of the buildings. identifies the synoptic situations that led to the emergence of convective systems by analyzing the temperature and geopotential parameters at standard levels. The degree of instability of the atmosphere is assessed on the basis of instability indices (CAPE, LI, VTI). The mesoscale analysis was realized and the evolution of the systems that generated the wind was monitored by satellite and radar imaging.
