The dataset contains post-processed model output of idealized baroclinic life cycle simulations performed with the atmospheric component of the Icosahedral Nonhydrostatic model (ICON-NWP; version 2.6.2.2). There are 12 experiments with 6 different initial climatic conditions: (1) present day (CTL); (2) uniform +4 K warming & moistening (4K); (3) uniform +4K warming but not moistening (4K_qvCTL); (4) non-uniform warming and moistening as anticipated by a CMIP6 model for the end of the 21st century under the high-emissions scenario SSP5-8.5 (Tanom); (5) tropical warming&moistening (Tanom_tropics); (6) polar warming&moistening (Tanom_polar), each performed with 2 different model grid spacing (80 km and 2.5 km).
