RISWarm Conveyor Belts in the ERA-Interim Dataset (1979–2010). Part II: Moisture Origin and Relevance for Precipitation
Publisher: American Meteorological Society
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 ...
Warm Conveyor Belts in the ERA-Interim Dataset (1979–2010). Part I: Climatology and Potential Vorticity Evolution
Publisher: American Meteorological Society
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 ...
Mechanisms of Regional Winter Sea-Ice Variability in a Warming Arctic

On the Co-Occurrence of Warm Conveyor Belt Outflows and PV Streamers
Publisher: American Meteorological Society
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, ...
Global Relationship between Fronts and Warm Conveyor Belts and the Impact on Extreme Precipitation
Publisher: American Meteorological Society
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 ...

Global climatologies of Eulerian and Lagrangian flow features based on ERA-Interim reanalyses
Publisher: American Meteorological Society
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, ...
Daily to Decadal Modulation of Jet Variability
Publisher: American Meteorological Society
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 ...
