Climate Sensitivity and Variability Examined in a Global Climate Model

The climate system covers a large span of spatial and temporal time-scales, which range from molecular length scale and fractions of a second to global extension and thousands of years. The former are displayed in the micro physics of a cloud drop, while the latter can be found in the deep circulation of the ocean. The scale interaction gives rise to the complexity of the climate system. In the presented projects, two important aspects of the climate system are explored: its sensitivity to external forcing and its internal variability.
