Abstract

Error of quantitative rainfall estimations due to partial or total weather radar beam blockage is important in complex orographic areas. A simple method named dynamical weather radar beam blockage correction different from the operational “look-up” table method is presented. The dynamical correction method is implemented with the multiplicative factor between two antenna elevation angles. Case study of quantitative rainfall estimation shows that the dynamical beam blockage correction is effective if the beam blockage azimuths are less than 10 degrees.
