Correlations between Maximum Rate of Precipitation and Mesoscale Parameters

Abstract
Daily 5, 10 and 30 min maxima of precipitation rate determined from a raingage network and radar were correlated with parcel convective energies, upper air humidity, height of parcel convection and maxima of surface conditions. After a selection of 54 well-documented cases the correlation coefficient between the maximum of rain rate over 5 min and the maximum convective energy was ρ = 0.79 for all cases and ρ = 0.89 for 15 air mass cases. Introducing the upper air humidity further improves the correlations.
