Two instruments have been used to measure the rate of rainfall from tropical clouds over the windward coast of the Island of Hawaii. The Workman intensity gauge employs strain gauges to sense the deflection in a movable trough and hence the flow of water down the trough. The Raymond-Wilson gauge, a new instrument developed during this program, measures the electrical resistance of flowing water to determine the rainfall rate. These instruments were deployed in a small scale array of eight gauges to measure space and time variations in high intensity rainfall as showers move across the network. Comparative measurements were made with a standard weighing rain gauge, a tipping bucket rain gauge and the Jardi rate of rainfall gauge. Both the Workman gauge and the Raymond-Wilson gauge are clearly superior to the other instruments, because of their rapid response time and their capacity to measure high intensity showers continuously and automatically.
