Assessment of Radar Reflectivity-Rainfall Rate, Z-R Relationships for a Convective Event in Malaysia

Various relationships between radar reflectivity and rainfall rate R commonly identified as Z-R have been derived in order to provide better for rainfall rate estimation using weather radar. It critical for the air traffic management at the airport to detect existence of potential microburst and wind . There are numerous factors that can certainly affect accuracy of Z-R relationships including poor hardware . However, the inaccuracy of Z-R relationships might be due to the differences between the at the ground level and the precipitation aloft radar does not scan all the way down except at close . Several Z-R relationships had also been proposed in attempt to achieve better accuracy for rainfall estimates radar system in the tropical region. Nonetheless, the most Z-R relationship for Malaysia weather radar is yet be investigated and to be identified within the study . This paper presents the preliminary analyses of proposed Z-R relationships for Malaysia weather new radar data and ground rainfall rate. were made between values obtained from the proposed relationships for radar and the ground measurements. It was identified that the previously relationships estimations are significantly lower the rain gauge data.
