ABSTRACT. - Some aspects of the relationship between synoptic-scale wind and convective cells’ motion generating heavy rains in the north-west of Romania. The paper examines some aspects of the relationship between synoptic-scale wind parameters and those of convective cells that generate heavy rainstorms. In this respect, torrential rains from 14 weather stations in the north-western Romania were analyzed, torrential characteristic being determined based on the Hellman criteria. Analyzing radar information, we determined a number of dynamic parameters of convective cells (direction and speed), taking into account synoptic scale conditions.
Analysis of the results reveals a number of features of the dynamics of convective cells by synoptic-scale circulation of each case, being a starting point in forecasting the spatial development of such nuclei generating convective rains.
