RADAR CLIMATOLOGY OF HAIL IN THE APUSENI MOUNTAINS
N. MAIER , I. HAIDU
ABSTRACT. - Radar Climatology of hail in the Apuseni Mountains A new method for
the assessment of large areas with frequent occurrence of hail in a fine spatial
resolution and its application for the Apuseni Mountains and their adjacent
areas is presented. Due to the fine tempo-spatial resolution of the radar
detection, the creation of radar climatology of the areas where the hail
production conditions are determined is imposed. With the help of two Doppler
radars at Oradea and Bobohalma, the area of interest is examined and spatial
maps of the relative frequency of hail contained in the clouds are made.
Composite maps are made (by superimposing the two Doppler radar images from
Oradea and Bobohalma) of the areas in which clouds with hail of different sizes
occur.
Keywords: hail, Doppler radar.
