Wind induced undercatch on rainfall measurements: implications on flood forecasting
Rainfall measurements are currently prone to substantial undercatch due to wind related errors. As the wind approaches the rim of the rain gauge it accelerates, as a result it removes a percentage (as much as 20%) of the rainfall that would have been collected in the device. Rainfall is the critical component of the hydrological cycle. When inaccurately measured water balance and flood warnings are all subject to error.
