Abstract

Intense rainfall is a significant factor affecting communication systems as radio signals interact with raindrops along their propagation path in the troposphere. However, the spatial and temporal variability of rainfall makes its measurement and prediction challenging. This study endeavors to investigate statistical methodologies for predicting time series values of rain rate using rainfall data collected for seven months in the year 2014's rainy season. The collection was gathered by the Communication Physics Research Group using the Micro Rain Radar installed within the Department of Physics. The study focuses on understanding rain rate patterns across various heights, with particular attention to the 320m height due to the susceptibility of the 160m height to near-field effects. After outlier removal, statistical distributions and monthly trends were analyzed, revealing distinct peaks and clustering of rain occurrences post-August. The First Order, regressive model, auto regressive model and Auto Regressive Moving Average (ARMA)models has been used in predicting time series values of rain rate. Ultimately, the ARMA model emerged as the most effective, leveraging both autoregressive and moving average components to enhance predictive accuracy by capturing complex data dependencies.
