Abstract A model is developed for use in estimating rainfall attenuation at frequencies above 3 GHz in showers and other types of sporadic rainfall, usually associated with atmospheric convective activity. The model assumes a spherical distribution of rainfall rate in an individual shower. The approximate rainfall attenuation and its maximum expected value are calculated at 10 GHz through a severe thunderstorm, and through some shower patterns. The variation of attenuation as individual cells move along a ray path is also given. It is concluded that this method of attenuation estimation could be particularly useful in analyzing radar data to determine the attenuation effects of convective activity.
