Abstract

This study was prompted by a need to explain an anomaly in the apparent precipitation distribution over a prominent mountain subject to a high velocity westerly airstream. Historical data reveal that the lee receives 58% more precipitation than the summit. A novel rain gauge with a vertically orientated collecting orifice, 3 standard rain gauges and complementary wind data were procured from 3 sites on the mountain to assess the effect of the airstream on the precipitation distribution. The catch efficiency of standard rain gauges decrease after the wind velocity exceeds 2.5 ms -1 Results indicate that the summit actually receives 59% more precipitation than the lee, where a vortex directly affects the precipitation distribution over, and east, of the mountain. © 1995 Springer-Verlag.
