Regime dependent instability as a transition mechanism in large-scale atmospheric flow
regimes instability baroclinic
2015/9/30
Two apparently distinct approaches to studying the observed low frequency variability in the atmosphere have evolved over the past few years. One approach invokes multiple, recurrent flow regimes to e...
Mediterranean hurricanes: large-scale environment and convective and precipitating areas from satellite microwave observations
Mediterranean hurricanes large-scale environment convective precipitating areas satellite microwave observations
2011/1/19
Subsynoptic scale vortices that have been likened to tropical cyclones or polar lows (medicanes) are occasionally observed over the Mediterranean Sea. Generated over the sea, they are usually associat...
Cyclones causing wind storms in the Mediterranean: characteristics, trends and links to large-scale patterns
Cyclones causing wind storms characteristics trends links to large-scale patterns
2010/10/21
A climatology of cyclones with a focus on their relation to wind storm tracks in the Mediterranean region (MR) is presented. Trends in the frequency of cyclones and wind storms, as well as variations ...
Parameterization of subgrid plume dilution for use in large-scale atmospheric simulations
Parameterization subgrid plume dilution large-scale atmospheric simulations
2010/3/16
A new model of plume dynamics has been developed for use as a subgrid model of plume dilution in a large-scale atmospheric simulation. The model uses mean wind, shear, and diffusion parameters derived...
Chaotic background of large-scale climate oscillations
Chaotic background large-scale climate oscillations
2010/4/6
It is shown that the periodic alteration of night and day provides a chaotic dissipation mechanism for the North Atlantic (NAO) and Southern (SOI) climate oscillations. The wavelet regression detrende...
Large-scale upper tropospheric pollution observed by MIPAS HCN and C2H6 global distributions
Large-scale upper tropospheric pollution MIPAS HCN C2H6
2009/12/31
We present global upper tropospheric HCN and C2H6 amounts derived from MIPAS/ENVISAT limb emission spectra. HCN and C2H6 are retrieved in the spectral regions 715.5–782.7 cm−1 and 811.5–835.7 cm...
An elevated large-scale dust veil from the Taklimakan Desert: Intercontinental transport and three-dimensional structure as captured by CALIPSO and regional and global models
large-scale dust Taklimakan Desert CALIPSO
2009/11/19
An intense dust storm occurred during 19–20 May 2007 over the Taklimakan Desert in northwestern China. Over the following days, the space-borne lidar CALIOP tracked an optically thin, highly elevated,...

Global chemical weather forecasts for field campaign planning: predictions and observations of large-scale features during MINOS, CONTRACE, and INDOEX
Global chemical weather forecasts MINOS CONTRACE INDOEX
2009/3/10
The first global tropospheric forecasts of O3 and its precursors have been used in the daily flight planning of field measurement campaigns. The 3-D chemistry-transport model MATCH-MPIC is driven by m...
Modelling tracer transport by a cumulus ensemble: lateral boundary conditions and large-scale ascent
Modelling tracer transport by a cumulus ensemble: lateral boundary conditions and large-scale ascent
2009/3/5
The vertical transport of tracers by a cumulus ensemble at the TOGA-COARE site is modelled during a 7 day episode using 2-D and 3-D cloud-resolving setups of the Weather Research and Forecast (WRF) mo...

Large-scale validation SCIAMACHY reflectance ultraviolet
2009/2/16
In this paper we present an extensive validation of calibrated SCIAMACHY nadir reflectance in the UV (240-400 nm) by comparison with spectra calculated with a fast radiative transfer model. We use ope...
Large-scale atmospheric circulation biases and changes in global climate model simulations and their importance for climate change in Central Europe
Large-scale atmospheric circulation global climate model simulations Central Europe
2009/1/5
The quality of global sea level pressure patterns has been assessed for simulations by 23 coupled climate models. Most models showed high pattern correlations. With respect to the explained spatial va...
