1. Roughness lengths and roughness sublayer corrections in partly forested regions
Abstract : Questions related to water resources management and climate change at regional to global scales have inspired research about processes governing exchange of water, heat and carbon between land and atmosphere. The concept of roughness length is fundamental in deduction of bulk transfer relations from the generally accepted Monin-Obukhov similarity theory for this exchange. READ MORE

2. Submicrometre aerosol emissions from sea spray and road traffic
Abstract : The uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.

3. Introducing Surface Gravity Waves into Earth System Models
Abstract : Surface gravity waves alter the turbulence of the bottom atmosphere and the upper ocean. Accordingly, they can affect momentum flux, heat fluxes, gas exchange and atmospheric mixing. However, in most state-of-the-art Earth System Models (ESMs), surface wave influences are not fully considered or even included. READ MORE

4. Water and heat exchange processes over the Baltic sea
Abstract : Before we can reach understanding of the global climate and predict climate changes accurately we must be able to understand water and energy budgets. The atmosphere-water exchange processes are of great importance. READ MORE

5. The role of high-latitude circulation and moisture transport in Arctic climate variability and change during winter
Abstract : This thesis examines the connections between atmospheric circulation in the high-latitudes, northward moisture transport, and Arctic climate variability and change during winter. An event based approach is taken by objectively defining phenomena termed “moisture intrusions” -- filamentary flows of anomalously moist air which originate at 70°N and cross the entire Arctic basin.
