Observasi Awan Dan Hujan Menggunakan X-Doppler Radar Di Sumatera Barat

Abstract

XDR (X-Doppler Radar) is a weather radar which is used Doppler effect to measure Objectvelocity (Cloud and Rain). XDR have been Installed in Sungai puar (0.36_S, 100.41_E, 1121MSL), agam District, West Sumatera. Range Observation of XDR is about 83 km with antennaazimuth scan 360 degree and antenna elevation is from 0.6 degree until 40 degree. By usingDRAFT software which is developed bu Hokkaido University, Japan, RAW data which takenfrom observation can be changed to XY data, and by using grads, this data will giveinformation to us about PPI, CAPPI, Vertical-Cross Section. Then by using Vis5D we also canfigured out two dimensional of cloud. From those data we may know cloud and rain movementpattern in West Sumatera. This is very usefull to study about the weather in West SumateraHal.489-49
