Variation with height of radar reflectivity factors due to rain and the influence of wind shear on rain cells

A 10 cm (*) radar has been used on the steerable 25 m diameter aerial at Chilbolton, U.K., to produce detailed threedimensional maps of raincell distribution and intensity. The present paper examines differences in variation of radar reflectivity with height from the model at present recommended by theCcir.Wind shear can have a considerable influence on the distribution of rain as it falls, and may cause a 45° angle of inclination of a cell. This remains constant as the rain cell travels and is usually offset from the direction of travel of the cell. The information on the variation of radar reflectivity with height and the inclination of the rain cells are each important in the field of radio communications.
