Generation of free convection due to changes of the local circulation system
free convection local circulation system
2009/11/19
Eddy-covariance and Sodar/RASS experimental measurement data of the COPS (Convective and Orographically-induced Precipitation Study) field campaign 2007 are used to investigate the generation of near-...
The impact of weather and atmospheric circulation on O3 and PM10 levels at a rural mid-latitude site
weather and atmospheric circulation O3 PM10 levels rural mid-latitude site
2009/5/6
In spite of the strict EU regulations, concentrations of surface ozone and PM10 often exceed the pollution standards for the Netherlands and Europe. Their concentrations are controlled by (precursor) ...
Sensitivity of aerosol concentrations and cloud properties to nucleation and secondary organic distribution in ECHAM5-HAM global circulation model
aerosol concentrations cloud properties secondary organic distribution ECHAM5-HAM global circulation model
2009/3/13
The global aerosol-climate model ECHAM5-HAM was modified to improve the representation of new particle formation in the boundary layer. Activation-type nucleation mechanism was introduced to produce o...
Simulation of the climate impact of Mt. Pinatubo eruption using ECHAM5 – Part 1: Sensitivity to the modes of atmospheric circulation and boundary conditions
climate impact Mt. Pinatubo eruption ECHAM5 atmospheric circulation boundary conditions
2009/3/12
The eruption of Mt. Pinatubo in the Philippines in June 1991 was one of the strongest volcanic eruptions in the 20th century and this well observed eruption can serve as an important case study to und...
Black carbon ageing in the Canadian Centre for Climate modelling and analysis atmospheric general circulation model
Black carbon Canadian Centre atmospheric general circulation model
2009/2/12
Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type...
The mean meridional circulation and midlatitude ozone buildup
mean meridional circulation midlatitude ozone buildup
2009/1/14
The wintertime ozone buildup over the Northern Hemisphere (NH) midlatitudes and its connection with the mean meridional circulation in the stratosphere are examined statistically on a monthly basis fr...
Interactive chemistry in the Laboratoire de Météorologie Dynamique general circulation model: model description and impact analysis of biogenic hydrocarbons on tropospheric chemistry
Interactive chemistry Laboratoire de Météorologie Dynamique general circulation model biogenic hydrocarbons tropospheric chemistry
2009/1/9
We present a description and evaluation of LMDz-INCA, a global three-dimensional chemistry-climate model, pertaining to its recently developed NMHC version. In this substantially extended version of t...
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...
Simulating organic species with the global atmospheric chemistry general circulation model ECHAM5/MESSy1: a comparison of model results with observations
organic species global atmospheric chemistry ECHAM5/MESSy
2008/12/10
The atmospheric-chemistry general circulation model ECHAM5/MESSy1 is evaluated with observations of different organic ozone precursors. This study continues a prior analysis which focused primarily on...
