Abstract
A short description of the so-called øresund experiment is given. The project studies the atmospheric dispersion process and modifications in the wind field across the 20-km wide øresund strait between Denmark and Sweden. The meteorological observational network extended over a 80-km wide cross section through the øresund. The dispersion process was investigated by carrying out SF6 tracer experiments. Wind and temperature data obtained on June 5, 1984 during the øresund experiment are analysed. On that day the water surface was colder than the land area. The near-surface winds were found to accelerate over the water near the upwind coast, subsequently decelerated as the water fetch increased, and accelerated once again as the second land surface was encountered. The complicated behaviour of the lower level wind fields is explained by a combination of roughness length changes and the development of a shallow stable layer over the water that inhibits vertical momentum transfer.
