HIGH RESOLUTION PRECIPITATION ANALYSIS OVER COMPLEX TERRAIN BY USING PHYSICAL A PRIORI KNOWLEDGE

The fingerprint concept (i.e. a physical model used for downscaling) related to the objective highresolution 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

Integrating nowcasting with crisis management and risk prevention in a transnational and interdisciplinary framework

This paper presents the recent WWRP/WMO Forecast Demonstration Project INCA-CE (INtegrating nowCAsting for Central Europe) co-funded by the European Union. Twenty-four partners of national and regional hydro-meteorological services, national and regional crisis and disaster management centers, and authorities for road management world-wide have participated in INCA-CE for international cooperation on nowcasting development, interdisciplinary cooperation for nowcasting applications and transnational cooperation for nowcasting services. INCA-CE has implemented the nowcasting system INCA at the project partner countries, applied INCA nowcasting in civil protection, operational hydrology and road safety, and improved the INCA system based on the end user's requirements. The main difference to other similar projects is that end user's involvement and the improvements involve the whole end user value chain. The project has developed several ideas for end users on how to interpret nowcasting products (INCA-SWING) and on how to deal with the nowcasting products in their working practice (INCA-MCPEX and ISW). INCA-CE is also oriented strongly to transnational cooperation in nowcasting development and implementation, in easy access to a homogenized set of nowcasting products from those INCA providers to end users in the region, and in the transnational use of real-time products by end users in cases of high impact weather across borders
