Analysis of the Synthetic Storm Technique Using Rain Height Models to Predict Rain Attenuation in Tropical Regions

Abstract

This paper aims to investigate the utilization of the Synthetic Storm Technique (SST) to convert rain rate time series to rain attenuation time series using the ITU-R P.839, Stutz man and Bryant rain height models. Furthermore, the study aims to compare the actual rain attenuation with that predicted by the SST using the three above-mentioned rain height models based on rain rate and rain attenuation both measured concurrently. The study relies on rain rate time series and rain attenuation time series measured at University Science Malaysia (USM) campus (4.390 N, 100.980 E). The study found that the higher the rain rate, the higher is the percentage error for the SST predicated rain attenuation using the three above-mentioned rain height models as compared with measured rain attenuation. However, it is observed that when the Stutz man model applied as part of the SST model, the prediction is more accurate of the three rain height models.
