Abstract

Rain angle and direction were measured using four variations of the Rose-Farbrother vectopluviometer and new device called a pole vectopluviometer. Gauge wind loss andgauge wind interference related to wind speed, direction and rainfall intensity caused substantial differences in the rain angle and rain direction estimates between the different vectopluviometers. Although no absolute standard device exists, the pole vectopluviometer, a fluted pole divided intofour sectors, provided the estimates of rainfall direction which most closely agreed with anemometer data and is intrinsically able to estimate average rain angle independently of direction
