Abstract: he role of moisture for extratropical atmospheric dynamics is particularly pronounced within warm conveyor belts (WCBs), which are characterized by intense latent heat release and precipitation formation. Based on the WCB ...

Abstract: global climatology of warm conveyor belts (WCBs) is presented for the years 1979?2010, based on trajectories calculated with Interim ECMWF Re-Analysis (ERA-Interim) data. WCB trajectories are identified as strongly ascending ...

Abstract: he co-occurrence of warm conveyor belts (WCBs), strongly ascending moist airstreams in extratropical cyclones, and stratospheric potential vorticity (PV) streamers, indicators for breaking Rossby waves on the tropopause, ...

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: his paper introduces a newly compiled set of feature-based climatologies identified from ERA-Interim reanalyses (1979?2014). Two categories of flow features are considered: (i) Eulerian climatologies of jet streams, ...

Abstract: AbstractThe variance of a jet?s position in latitude is found to be related to its average speed: when a jet becomes stronger, its variability in latitude decreases. This relationship is shown to hold for observed midlatitude ...
