Northern Hemisphere Rossby Wave Initiation Events on the Extratropical Jet—A Climatological Analysis
TL;DR: In this paper, a climatology of Rossby wave initiation (RWI) events on the Northern Hemisphere mid-latitude jet is compiled by applying an objective RWI identification algorithm to the ERA-Interim re-analysis dataset.
Journal ArticleDOI
Transport timescales and tracer properties in the extratropical UTLS
TL;DR: In this article, a comprehensive evaluation of seasonal backward trajectories initialized in the northern hemisphere lowermost stratosphere (LMS) has been performed to investigate the factors that determine the temporal and spatial structure of troposphere-to-stratosphere-transport and it's impact on the LMS.
Journal ArticleDOI
When during Their Life Cycle Are Extratropical Cyclones Attended by Fronts
TL;DR: For nearly a century, the study of atmospheric dynamics in the midlatitudes has presented dichotomic perspectives on one of its focal points: the birth and life cycle of cyclones as discussed by the authors.
Journal ArticleDOI
Processes leading to heavy precipitation associated with two Mediterranean cyclones observed during the HyMeX SOP1
Emmanouil Flaounas,Konstantinos Lagouvardos,Vassiliki Kotroni,Chantal Claud,Julien Delanoë,Cyrille Flamant,Erica Madonna,Heini Wernli +7 more
TL;DR: In this paper, the authors combine complementary observations from airborne radar and lidar systems, ZEUS lightning detection network and meteorological surface stations along with satellite diagnostics on deep convection, for a detailed microphysics and (thermo-)dynamical analysis of the two extreme rainfall cases.
Journal ArticleDOI

TL;DR: In this article, a new cloud stabilization mechanism is proposed based on upwelling of the air of some mm/s to balance the ice particles, supersaturation with respect to ice above and subsaturation below the tropical tropopause.
