| description | This paper aims to analyse the precipitation quantities measured during August, 2020 at the meteorological stations and gauging stations in north-western Romania, compared to the WSR-98D Doppler weather radar estimations. This study was motivated by the presence of major differences in the precipitations field between both radar estimations and gauging stations measurements, and this paper aims to identify the factors that led to these differences. The results showed that during convective and pre-frontal situations, the WSR-98D Oradea (RDOD) and WSR-98D Bobohalma (RDBB) weather radars detected the water amounts and their maximum quantities. Hence, RDOD detects precipitation with a higher accuracy for the Apuseni Mountains and the western part of Cluj and Sălaj counties, while RDBB detects the amounts of precipitations for about the entire area. During frontal situations, when the frontal systems occur early in the morning, the estimations are less accurate, but once more, RDBB detects the area with important rainfall amounts, yet underestimated. |
