Present weather may be summarised as falling into a number of different categories: • Showery precipitation with thunderstorm • Showery precipitation without thunderstorm • Frozen precipitation • Freezing rain or sleet

They noticed that noise in returning echoes was associated with weather elements such as rain, sleet and snow
