1. Mesoscale Simulations of Atmospheric Flow in Complex Terrain
Sammanfattning : The MIUU mesoscale model was further developed, in order to include information on large-scale atmospheric fields from global or regional atmospheric climate- and weather-prediction models. For this purpose, a new lateral boundary condition was developed and implemented into the model. LÄS MER
2. Analysis of Arctic ice cloud properties using in-situ and remote sensing measurements
Sammanfattning : Cirrus clouds play an important role in the radiation balance of the atmosphere as theycan have a warming and cooling effect. The resulting net radiation effect depends ontheir micro- and macrophysical properties such as particle size, shape, and numberconcentration. LÄS MER
3. Wind Turbine Sound Propagation in the Atmospheric Boundary Layer
Sammanfattning : Wind turbines have grown both in size and number in the past decades. The taller turbines has made it possible to place them in forest areas which is fortunate for a country like Sweden with lots of forest. An issue with wind turbines is the sound they produce. The sound mainly comes from the rotor blades when they pass through the air. LÄS MER
4. Mesospheric measurements using microwave spectroscopy
Sammanfattning : The mesosphere is an altitude region of the atmosphere, covering altitudes between about 50 km to 100 km. Improved understanding of this area of the atmosphere offers possibilities of increasing the accuracy of weather forecast and climate models. LÄS MER
5. Dispersion modelling of volcanic emissions
Sammanfattning : Gases and particles released by volcanoes pose a serious hazard to humans and society. Emissions can be transported over long distances before being reduced to harmless concentrations. Knowing which areas are, or will be, exposed to volcanic emissions is an important part inreducing the impact on human health and society. LÄS MER
