摘要:... A central goal is the statistical evaluation of precipitation forecasts with dynamic parameters. Here, the Dynamic State Index ( DSI ) is used as a dynamic threshold parameter. The DSI theoretically describes the change of atmospheric flow fields as deviations from a station...

摘要:The present study investigates the phenomenon of atmospheric blocking using a cascade of Dynamic State Indices. The different DSI variants signalize model dependent aspects of atmospheric blockings, which allows for a scale-dependent analysis of the corresponding flow pattern. St...

摘要:The Dynamic State Index (DSI) basing on the Energy-Vorticity Theory is able to detect all non-stationary and diabatic processes in the atmosphere. It is shown for the first time that the index is practicable for diagnostic analysis of the synoptic scale, in particular on press...

摘要:... We propose a newly designed Dynamic State Index ( DSI ) to evaluate precipitation processes. The DSI is presented in the context of a case study in the synoptic scale and in a statistical approach. The DSI quantitatively describes the deviation from a stationary, adiabatic an...

摘要:... In order to improve the initial state of COSMO-DE an assimilation of radar derived precipitation rates is applied by using “Latent Heat Nudging” (LHN). The aim of LHN is to adjust the model state so that the model will respond by producing a rain rate close to the obser...

摘要:Abstract The Dynamic State Index (DSI) is a scalar diagnostic field that quantifies local deviations from a steady and adiabatic wind solution and thus indicates non-stationarity aswell as diabaticity. The DSI-concept has originally been developed through the Energy-Vorticity ...

摘要:... A dynamic state index (DSI) and a chemical state index (CSI) can be defined for the diagnosis of the weather and climate system as a practical application of this theory.

摘要:... For this purpose the newly designed Dynamic State Index ( DSI ) is correlated with clouds and precipitation. The DSI quantitatively describes the deviation and relative distance from a stationary and adiabatic solution of the primitive equations. A case study and statistical ...
