Theoretical understanding and numerical modeling of atmospheric moist convection still pose great challenges to meteorological research. One of the difficulties is the multi-scale nature of the phenomena involved. For the first time adaptive methods of scientific computing are applied in our project to model the interaction of diverse scales of cloud dynamics. Starting point for the development were preliminary studies of the involved scientists in meteorological modeling as well as adaptive mesh techniques. Both streams of development were joined in this project. Therefore a new numerical model was implemented (see model-webpage). As a next step moisture will be included and extended to the full 3D case. The key application is the mixing-induced bouyancy reversal. The project belongs to the priority programMetStröm of the Deutsche Forschungsgemeinschaft (German Research Foundation).
