Abstract: The statistical morphology of radar reflectivity is a function of horizontal and vertical extension of rain is of considerable interest to those assessing the possible interference between terrestrial links and earth -space satellite links. In this paper, the horizontal and vertical extension of rain deduced from radar plan position indicator (PPI ) and range height indicator (RHI) measurements have been presented. Such results of rain extension have also been deduced as a function of radar reflectivity factor (dBz). The radar reflectivity factor is the measure of the strength of the scattering cross-section of the rain cells. The scattering cross-section is responsible for causing interference to the radio signals. Probability distribution of radar reflectivity (dBz) deduced from both horizontal (PPI) and vertical extension (RHI) of rain cells has also been estimated.
