Abstract: Singular vectors with maximum energy at final time inside a verification area are used to identify the target area where extra observations should be taken, at an initial time, to reduce the forecast error inside the ...

Abstract: A high-resolution atmospheric ensemble forecasting system is coupled to a hydrologic model to investigate probabilistic runoff forecasts for the alpine tributaries of the Rhine River basin (34 550 km2). Five-day ensemble ...

Abstract: This paper focuses on the coupling between an ex?tropical cyclone and two preexisting mesoscale tropopause depressions (TDs). The TDs approached the cyclone from widely separated sources after becoming cut off from different ...
