Research Themes of Section Atmospheric Circulation
The research of the section Atmospheric Circulation aims to increase our knowledge
- on the variability of the climate on decadal scales,
- on circulation structures of the atmosphere,
- on trace constituents in the polar atmosphere, and
- to perform scenarios of polar climate changes.
These activities can be roughly categorised in three linked topics:
Climate modelling
- Regional climate simulation with HIRHAM
- Natural decadal climate variability
- Global implications of Arctic climate processes and feedbacks - GLIMPSE
- Quantifying the carbon budget in Northern Russia: past, present and future (CARBO-North)
- Stratospheric mixing
- Adaptive atmospheric model development on unstructured grids
Aerosol Characterization of aerosol and cloud particles in the atmosphere
- Characterization of aerosol and cloud particles in the atmosphere world-wide with the Mobile NDACC Lidar systems
- Tropospheric Aerosols in the Arctic:
- Investigations of Arctic Haze with an air-borne lidar
- Aerosol forcing due to Arctic haze
- Long term observations of aerosols and clouds in Spitsbergen with a Tropo-Lidar
- Arctic Study on Tropospheric Aerosol and Radiation (ASTAR)
Campaigns: March/April 2000, May/June 2004, and March/April 2007. - Investigations of Polar Stratospheric Clouds
- Aerosol Optical Density measurements with sun and star photometers
Ozone and related trace gases
- Balloone-borne ozone observations and meteorological measurements at AWI's Arctic station
- Measurements of chemical ozone loss in the Arctic stratosphere by means of coordinated balloon observations (Match)
- Ozone chemistry of the Arctic stratosphere
- Stratospheric water vapour measurements
- Chemical and dynamical influences on decadal ozone changes - CANDIDOZ
