Abstract

This study investigates the impact of different rain classifications and elevation angles on copolar attenuation, a critical factor influencing radio wave propagation in communication systems operating in adverse weather conditions. Using data collected over the years 2021 and 2022 in Warri, Delta State of Nigeria. Copolar attenuation values at 400 and 600 elevation angles were analyzed across various rain classifications, including Drizzle, Widespread, Shower, Cloudburst, and Extreme Cloudburst. The results highlight that higher intensity rain events, such as Cloudburst and Extreme Cloudburst, lead to significantly greater copolar attenuation compared to lower intensity rain classifications. Furthermore, the sensitivity of copolar attenuation to elevation angle is observed, with higher angles generally associated with lower attenuation values. These findings underscore the importance of considering rain intensity and elevation angle in the design and operation of communication systems to mitigate the effects of rain-induced attenuation and ensure reliable signal transmission. By optimizing antenna placement and orientation and employing adaptive communication techniques, such as adaptive modulation and coding, communication networks can be better equipped to maintain connectivity in challenging weather conditions.
