SFB 512 - Cyclones and the North Atlantic Climate System. The SFB is sponsered by DFG (project number ). Subproject F2 - Atmospheric water cycle components over the North Atlantic derived from satellite data. The project goal is the determination of the variability in the water cycle over the North Atlantic as a function of the North Atlantic Oscillation (NAO) from satellite data. Beyond the purely statistical analysis of these time series for the North Atlantic region and the correlation with the different phases of the NAO, the available fields will be analysed for individual cyclones in various stages of their life cycle (satellite and m o d e l data). This should clarify the importance of cyclones to the energy and water exchange between ocean and atmosphere. Comparison studies of such individual cases with model results will include standard ECMWF analysis as well as detailed regional modelling (REMO) results and will help to assess the quality of the water balance components in state of the art numerical weather prediction models. These data will also be applied to the study of changes in the water cycle components during the landfall of North Atlantic cyclones. The simulations have been performed with REMO 5.1 including the ECHAM 4 physics. Studies have been done for 1958-1998. For these investigations the regional model REMO has been used with a horizontal resolution of 1/6 degrees, a vertical resolution on 20 levels and a timestep of 100 seconds. As input at the boundaries and for initializations ERA40 in T106 resolution have been available.
