Simulating mixed-phase Arctic stratus clouds: sensitivity to ice initiation mechanisms
mixed-phase Arctic stratus clouds ice initiation mechanisms sensitivity
2009/7/23
The importance of Arctic mixed-phase clouds on radiation and the Arctic climate is well known. However, the development of mixed-phase cloud parameterization for use in large scale models is limited b...
Transport mechanisms for synoptic, seasonal and interannual SF6 variations and“age”of air in troposphere
Transport mechanisms synoptic seasonal interannual SF6 variations troposphere
2009/3/13
We use an atmospheric general circulation model (AGCM) driven chemistry-transport model (ACTM) to simulate the evolution of sulfur hexafluoride (SF6) in the troposphere. The model results are compared...
Freezing thresholds and cirrus cloud formation mechanisms inferred from in situ measurements of relative humidity
Freezing thresholds cirrus cloud formation mechanisms humidity
2009/3/11
Factors controlling the microphysical link between distributions of relative humidity above ice saturation in the upper troposphere and lowermost stratosphere and cirrus clouds are examined with the h...
Influence of mountain waves and NAT nucleation mechanisms on polar stratospheric cloud formation at local and synoptic scales during the 1999-2000 Arctic winter
mountain waves NAT nucleation mechanisms polar stratospheric cloud formation Arctic winter
2009/2/7
A scheme for introducing mountain wave-induced temperature pertubations in a microphysical PSC model has been developed. A data set of temperature fluctuations attributable to mountain waves as comput...
Atmospheric sulphuric acid and aerosol formation: implications from atmospheric measurements for nucleation and early growth mechanisms
Atmospheric sulphuric acid aerosol formation atmospheric measurements early growth mechanisms
2009/1/15
We have investigated the formation and early growth of atmospheric secondary aerosol particles building on atmospheric measurements. The measurements were part of the QUEST 2 campaign which took place...
An overview of snow photochemistry: evidence, mechanisms and impacts
snow photochemistry evidence mechanisms
2008/12/17
It has been shown that sunlit snow and ice plays an important role in processing atmospheric species. Photochemical production of a variety of chemicals has recently been reported to occur in snow/ice...
Case studies of particle formation events observed in boreal forests: implications for nucleation mechanisms
particle formation boreal forests nucleation mechanisms
2008/11/24
Aerosol nucleation events observed worldwide may have significant climatic and health implications. However, the specific nucleation mechanisms remain ambiguous. Here, we report case studies of eight ...
