Spatial correlations of short-term rainfall totals within a network of raingages have been used to characterize the nature of rainfall as being widespread or spotty. Diurnal variations in correlations have been found in an arid area, which indicated widespread rainfall to predominate during the relatively cool morning hours up to noontime, while spotty rainfall was at a maximum in the afternoon. This result fits to the previously found afternoon maximum of high-intensity rainfall, and reinforces the explanation of those variations as being forced by surface heat driven, small-scale convection.
