ABL process studies

We use novel observation and high-resolution (~100m) modelling approaches to unravel important processes in the atmospheric boundary layer (ABL). These include

  • moisture supply to the Atacama Desert through a combination of new station networks, ground-based remote sensing and satellite imagery (CRC1211),
  • formation and advection of cold air pools during strong thunderstorm events (FESSTVaL), which have high potential to re-initiate storms,
  • cloud and precipitaion formation from the Tropics to the Arctic, trying to find out when, where and why precipitation formation occurs,
  • vertical structure of turbulent processes (fluxes), which sometimes (but not always) govern the presence of clouds

The figure shows the study domain of the CRC1211. Magenta dots show newly installed weather stations, ground-based remote sensing sites were and are installed at Iquique and Paranal Observatory. Both observations allow deducing moisture transports in and out of the Atacama Desert, one of the driest regions of the Earth Figure courtesy of Christoph Böhm, University of Cologne
