Description

From the Summary:'Some of the characteristics of areal rainfall have been examined for the purposes of assessing the extent to which a point observation is representative of whether or not an area has received rain. Only summer rainfall data were considered, the season during which one would expect areal variability to be greatest and, hence, the areal representativeness of a single observing station, the least. On the average, out of every 8 days that rain was reported by at least 1 of the 30 available stations, a centrally located reference station managed to detect 5. When combined with an additional 4 satellite stations,7 out of every 8 were detected. A decision regarding rain occurrence over the whole area was found to be almost as accurate when it was based upon observations at one station as when based on a majority decision from observations at 30 stations. Further studies into the areal representativeness of a point observation should be made with consideration being given to rainfall amounts.'
