✦ Synopsis

A simple apparatus is described for evaluating the energy load and intensity of rainstorms relevant to studies of soil erosion and surface run-off. The instrument records graphically, on a time scale, the amplitude of electric pulses originating from the impact of raindrops on the surface of a transducer disc, by making use of the piezo-electric effect. The size distribution of raindrops is calculated by analysing the graphic records of pulses on the chart from the number and the amplitude of pulses, and from the measured volume of total rainfall. The apparatus can be assembled using commercially available materials and recorders. It combines easy handling with acceptable accuracy. * After Best (1950). ** After Bean and Wells (1953).

## Abstract Several studies have tried to determine the empirical relationships between the maximum urban heat island (UHI) intensity and factors such as the city size taking the number of inhabitants as indicator, the geometry of the city (i.e. the __H__/__W__ ratio), meteorological factors, etc.
