Abstract: resented here is a global analysis of frontal activity variability derived from ERA-Interim data over the 34-yr period of January 1979?March 2013 using a state-of-the-art frontal tracking scheme. In December?February over ...

Abstract: omposite analysis of North Atlantic midlatitudinal winter cyclones is performed using NCEP?NCAR reanalysis data for the 60-yr period from 1948 to 2007. The composites were developed using an advanced methodology involving ...

Abstract: Climatology of the atmospheric cyclone sizes and their change over the cyclone life cycle is analyzed on the basis of tracking 57 yr of NCEP?NCAR reanalysis sea level pressure data over the Northern Hemisphere. To quantify ...

Abstract: haracteristics of Northern Hemisphere extratropical cyclone activity were compared for five concurrent reanalyses: the NCEP?U.S. Department of Energy (DOE) reanalysis (herein NCEP?DOE), the Japanese 25-year Reanalysis ...

Abstract: n this study, the important role of extratropical cyclones and fronts for the atmospheric freshwater flux over the Southern Ocean is analyzed. Based on the Interim ECMWF Re-Analysis (ERA-Interim), the freshwater flux ...

Abstract: n objective climatology of anticyclones over the greater Mediterranean region is presented based on the Interim ECMWF Re-Analysis (ERA-Interim) for a 34-yr period (1979?2012) and the Melbourne University automatic ...

Abstract: xtratropical cyclones are responsible for many extreme precipitation events in the midlatitudes. Warm conveyor belts (WCBs) and fronts are known to be related to the uplift and hence the precipitation within cyclones. The ...

Abstract: bility of results from different automated methods of detection and tracking of extratropical cyclones is assessed in order to identify uncertainties related to the choice of method. Fifteen international teams applied ...
