1. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling
Abstract : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. READ MORE

2. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer
Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

3. Atmosphere-ocean Interactions in Swell Dominated Wave Fields
Abstract : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. READ MORE

4. Fluid Dynamics of the Transport Zone of Circulating Fluidized Beds - with Application to Boilers
Abstract : The particle suspension flow structure in circulating fluidized beds (CFB) was studied with emphasis on the layer of downflowing particles at the wall. The main experiments were carried out in the furnace of the 12 MWth CFB boiler of 1.7x1.7 m cross-section, and in a two-dimensional CFB cold bed of 0. READ MORE

5. The Representation of Atmospheric Boundary Layer Processes in Global Climate Models
Abstract : The atmospheric boundary layer is the lowest part of the atmosphere, which is in direct contact with the surface. It is here, in this turbulent layer, that the exchange of heat, moisture and momentum between the surface and the atmosphere takes place. READ MORE
