"This study compares the relative catch efficiency of standard horizontal raingauges with stereo-topped (sloping orifice) rain gauges on three slopes in Western Manitoba. The gauge sites are in a heavily instrumented basin where observations have been obtained for seven years. Respective catches were examined by seven year totals and also by separate storm totals. For identifiable upslope wind flows, the stereo gauges were more efficient by 13%. For downslope or lee winds, the stereo gauges caught 15% less than the adjacent standard gauges. The undercatch on lee slopes appeared to be independent of wind speed, whereas the efficiency on windward slopes increased with wind speed"--Abstract. Includes abstracts in English and French.
