Mutimodality appears in the modelling of rainfall drop size distributions (DSDs), and the understanding of the distribution in general is important as it helps in the predicting and mitigation of attenuation due to rain of satellite signals in frequencies above 10 GHz. This work looks at the occurrence of multimodality in the rainfall DSDs in southern England, with data captured at the Chilbolton Observatory for a seven year period (2003 to 2009). The investigation looks at the variation in the number of modes against different rain rates and seasons. It shows that multimodality is a relatively common occurrence, and hence there is a need to model this phenomenon when attempting to predict rain attenuation of satellite signals.
