Circulation and connection land-sea-atmosphere

Over long timescales, the circulation systems co-evolve with ice sheets, mountain ranges, and redistributions of carbon between the atmosphere, ocean and land. The circulation and associated feedbacks influence exchanges of energy and materials between compartments of the climate system, and create teleconnections and natural climate variability.

Polar Meteorology and Oceanography

The global warming is not uniformly distributed over the Earth. The polar regions are especially sensitive for climate change and the warming in the Arctic is more than twice as fast as for the Earth on average. The effects of this warming are large, with a dramatic loss of sea ice as an example.

Clouds, airborne particles and gases

A continued change in the atmospheric content of greenhouse gases and particles is estimated to result in future warming well above 1.5°C, compared with pre-industrial levels. It is uncertain how much heating is masked by the cooling effect of the particles, especially the effect of the particles on the distribution and properties of the clouds.

Research projects

The research is overall motivated by the concern about the effects of anthropogenic changes in the chemical composition of the atmosphere: impact on climate, ecosystems—including acidification—and human health. Studies of the occurrence of aerosol particles and gaseous constituents of importance for cloud radiative properties, biogeochemical cycles and climate play a central role in the research activities, with the emphasis on both the Arctic region in summer with a minimum of influences by man-made sources, and the heavily polluted Indian sub-continent. Examples are cycling of sulphur and marine biogenic matter, which provides a still poorly understood link between cloud radiative properties and marine microbiological life in ocean and ice, and the short lived climate tracer soot and its climate impact.

The research involves studies of the occurrence and transformation of chemical constituents in the atmosphere as dependent on homogenous and heteorogenous chemical reactions and meteorological conditions: winds, clouds, precipitation etc. The research is carried out as part of comprehensive international field campaigns (ASCOS: www.ascos.se and ABC: www.abc-asia.ucsd.edu). The field-work is complemented by laboratory studies and theoretical modelling of different complexity to examine how different chemical constituents interact with atmospheric mixing and transport. The models are used to interpret both the in-situ and remote sensing collected data and to study the impact of long-term past and future changes in atmospheric composition. I have a significant interdisciplinary expertise and extensive experience of managing large multidisciplinary institutional Arctic research programs in her role as deputy coordinator of the atmospheric program of four international Arctic Ocean Expeditions to the North Pole.
