Modelling daily precipitation as a function of temperature for climate change impact studies

A method is presented to derive time series of daily precipitation and temperature in a possible future climate at a certain location from the observed time series of these variables.
The method considers the relation between daily precipitation and temperature. From this relation a temperature dependent factor F is obtained which gives the relative change in daily precipitation due to a given temperature perturbation.
Multiplication of the observed daily amounts with this factor yields a consistent scenario for daily precipitation and temperature.
