1. The influence of clouds on Earth's radiation budget in global climate models
Sammanfattning : 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. LÄS MER
2. Asymptotic methods applied to some oceanography-related problems
Sammanfattning : In this thesis a number of issues related to oceanographic problems have been dealt with on the basis of applying asymptotic methods. The first study focused on the tidal generation of internal waves, a process which is quantifed by the conversion rates. These have traditionally been calculated by using the WKB approximation.

3. Tracing water transport pathways in the coupled ocean-atmosphere system
Sammanfattning : Water is the most precious substance on the Earth and thus it is important to know how it moves around and is recycled.This knowledge will be useful to formulate educated future strategies about water usage in society and also to understand the near-surface salinity contrasts in the world ocean.

4. Atmospheric and oceanic circulation from a thermodynamic perspective
Sammanfattning : The climate system is continuously transporting and exchanging heat, freshwater, carbon and other tracers in different spatio-temporal scales. Therefore, analysing the system from a thermodynamic or biogeochemical framework is highly convenient. LÄS MER
5. Tracing pathways in the ocean circulation : A temperature and salinity perspective
Sammanfattning : The ocean circulation plays an essential role in our climate system. It redistributes heat, salt, carbon and other tracers across the globe, making the climate of Earth more moderate. This thesis targets density differences that are driving the ocean circulation. These differences are caused by changes in temperature and salinity. LÄS MER
