31. Influence of External Factors on the Turbulence Structure in the Atmospheric Boundary Layer
Abstract : The theory used in today’s weather- and climate models to describe processes near the earth’s surface, i.e. transport of heat, moisture and momentum between the ground and the atmosphere, is based on the idea that only local factors are important, such as temperature and wind speed near the ground.

32. Modelling the middle atmosphere and its sensitivity to climate change
Abstract : The Earth's middle atmosphere at about 10-100 km has shown a substantial sensitivity to human activities. First, the ozone layer has been reduced since the the early 1980s due to man-made emissions of halogenated hydrocarbons. READ MORE

33. Some Concepts of Estuarine Modeling
Abstract : If an estuarine system is to be investigated using an oceanographic modeling approach, a decision must be made whether to use a simple and robust framework based on e.g. mass-balance considerations, or if a more advanced process-resolving three-dimensional (3-D) numerical model are necessary.

34. Noctilucent clouds in a coupled atmosphere
Abstract : Noctilucent clouds (NLC) at altitudes around 80 km are the highest clouds in our atmosphere. They have been a subject of research ever since their discovery in the late 19th century. This thesis takes an important step towards using NLC as a tool for studying dynamic coupling processes in the atmosphere on a global scale. READ MORE

35. The influence of clouds on Earth's radiation budget in global climate models
Abstract : Considering the high sensitivity of climate to changes in cloudiness, the way clouds might change in a perturbed climate is important for the total temperature response. In fact, the cloud feedback has been identified as the main uncertainty in future projections, as simulated by global climate models. READ MORE
