The study of the Mediterranean cyclones from a climatological point of view has been one of the objectives of the first phase of WMO WWRP MEDEX (MEDiterranean EXperiment) project. It has been revealin...
Water vapour transport in the tropical tropopause region in coupled Chemistry-Climate Models and ERA-40 reanalysis data
Water vapour transport tropical tropopause region coupled Chemistry-Climate Models
2009/5/6
In this study backward trajectories from the tropical lower stratosphere were calculated for the Northern Hemisphere (NH) winters 1995–1996, 1997–1998 (El Niño) and 1998–1999 (La Niña) a...
Evaluation of archived and off-line diagnosed vertical diffusion coefficients from ERA-40 with 222Rn simulations

Boundary layer turbulence has a profound influence on the distribution of tracers with sources or sinks at the surface. The 40-year ERA-40 meteorological data set of the European Centre for Medium-ran...
Mid-latitude ozone changes: studies with a 3-D CTM forced by ERA-40 analyses
Mid-latitude ozone 3-D CTM ERA-40
2008/12/9
We have used an off-line three-dimensional (3-D) chemical transport model (CTM) to study long-term changes in stratospheric O3. The model was run from 1977–2004 and forced by ECMWF ERA-40 and operatio...
Differences between the QBO in the first and in the second half of the ERA-40 reanalysis
QBO ERA-40
2008/12/1
The representation of the quasi-biennial oscillation (QBO) is investigated in the ERA-40 reanalysis. In the lower stratosphere, where there are a reasonable number of observations, the representation ...
Evaluation of ECMWF ERA-40 temperature and wind in the lower tropical stratosphere since 1988 from past long-duration balloon measurements
ECMWF ERA-40 lower tropical stratosphere
2008/11/12
The temperature and wind of the ECMWF ERA-40 reanalysis in the tropical lower stratosphere during the period 1988–2001 has been evaluated by comparison with independent in situ measurements of 21 IR M...
