Abstract. We use a coupled atmosphere- re model to simulate a re that occurred on August 14{17, 2009, in the Harmanli region, Bulgaria.Data was obtained from GIS and satellites imagery, and from stan...
Experimental simulation of satellite observations of 100 kHz radio waves from relativistic electron beams above thunderclouds
satellite observations 100 kHz radio waves relativistic electron beams thunderclouds
2011/2/24
Relativistic electron beams above thunderclouds emit 100 kHz radio waves which illuminate the Earth's atmosphere and near-Earth space. This contribution aims to clarify the physical processes which ar...
Simulation of low clouds in the Southeast Pacific by the NCEP GFS: sensitivity to vertical mixing
low clouds the Southeast Pacific the NCEP GFS vertical mixing
2010/12/28
The NCEP Global Forecast System (GFS) model has an important systematic error shared by many other models: stratocumuli are missed over the subtropical eastern oceans. It is shown that this error can ...
Isotope effect in the formation of H2 from H2CO studied at the atmospheric simulation chamber SAPHIR
Isotope effect the formation of H2 from H2CO the atmospheric simulation chamber SAPHIR
2010/8/13
Formaldehyde of known, near-natural isotopic composition was photolyzed in the SAPHIR atmosphere simulation chamber under ambient conditions. The isotopic composition of the product H2 was used to det...
Evaluation of the volatility basis-set approach for the simulation of organic aerosol formation in the Mexico City metropolitan area

Due to its adverse effects on human health, atmospheric particulate matter (PM) constitutes a growing challenge for air quality management. It is also a complex subject of study. The understanding of ...
Comparison of a global-climate model simulation to a cloud-system resolving model simulation for long-term thin stratocumulus clouds
global-climate model cloud-system resolving model long-term thin stratocumulus clouds
2009/9/14
A case of thin, warm marine-boundary-layer (MBL) clouds is simulated by a cloud-system resolving model (CSRM) and is compared to the same case of clouds simulated by a general circulation model (GCM)....
The simulation of the Antarctic ozone hole by chemistry-climate models
Antarctic ozone hole chemistry-climate models
2009/9/11
While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used ...
Equilibrium of sinks and sources of sulphate over Europe: comparison between a six-year simulation and EMEP observations
sulphate Europe EMEP
