Abstract

The fingerprint concept (i.e. a physical model used for downscaling) related to the objective high-resolution analysis scheme VERA (Vienna Enhanced Resolution Analysis) is extended towards the use for precipitation analyses over complex topography. A fingerprint for upslope rain is developed which simulates the effects of air mass lifting and triggering of precipitation associated with a mountain slope, as well as the dependence of height. It further includes the decrease of accumulated precipitation in the relatively drier regions in the inner Alps. The background of the VERA analysis scheme is described as well as the different constraints made during the development of the fingerprint. Evaluations of analyses with and without fingerprint are presented.
