Geophysical Institute, Univ. of Bergen

I am a Associate Professor in atmospheric dynamics working at the Geophysical Institute, University of Bergen (GFI) and the Bjerknes Centre for Climate Research (BCCR) My main interests are synoptic to large scale meteorology and its impact on the water cycle. I am currently involved in climate related projects in the Arctic, northern Europe, Tibetan Plateau and the Ethiopian Highlands.

Heat and Moisture Transport, Cyclone variability

Arctic and sub arctic climate variability with special empahsis on the effect of cheat and moisture transport on the Arctic climate. The work includes working with a global streched model, a simplified 1D coupled atm-ice-ocen model (1DICE), a global couped model (BCM) and a stormtracking algorithm which provides an objective identification of storm trajectories giving the location and intensity of the local extremes of individual low and high pressure systems.

Heat and Moisture Transport, Cyclone variability, Hydrometeorology, Precipitation

Variations in the Norwegian climate is strongly linked to cyclone variability which govern the variations in heat and moisture into the country. This again gives large variations in themperaure, precipitation and snow cover. My work includes working observations, cyclone tracking and climate models.

Climate of the Tibetan Plateau , Hydrometeorology, Snow, Glaciers

The Tibetan Plateau is the source of some of the worlds largest rivers such as Yangtse, Irradwaddy, Salween, Mekong, Bramaputra and Ganges. Climate variability and change at the Tibetan Plateau directly affect the strengt and variability of the river discharge which may have large consequences for the millions of people that live in the vicinity of these rivers. My main interest is in observations and modelling of the hydrological cycle over the plateau. The work is done in cooperation with the University of Tibet and Tibet Meteorological Bureau.

Climate of the Ethiopian Highlands , Hydrometeorology, Malaria

Climate is effecting human health by bringing about variability in the ecology of infectious diseases. There are few practical tools to predict malaria epidemics based on climate forecasts. Such tools would be useful in making efficient use of the limited resources for malaria control. The work aim to incorporate climate variability and forecast information into a early warning system for malaria epidemics (EMAPS). My interest is in modelling and analysing the hyrometeorological conditions in east Africa using observations and a regional forecast and climate model (WRF) The work is done in cooperation with the National Meteorological Agency in Ethiopia, University of Arba Minch, Ethiopia, University of Addis Ababa, Ethiopia and Center for International Health, Univ. of Bergen.
