Abstract:
In this release version, we present Aeolus 2.0, an open-source numerical atmosphere model and a two-layer version of the improved moist-convective Rotating Shallow Water (2imcRSW) model. This particular iteration of Aeolus 2.0 stands as a self-contained model of intermediate complexity. The model's dynamical core is underpinned by a multi-layer pseudo-spectral moist-convective Thermal Rotating Shallow Water (mcTRSW) model. The pseudo-spectral problem-solving tasks are handled by the Dedalus algorithm, acknowledged for its spin-weighted spherical harmonics. The model captures the temporal and spatial evolution of vertically integrated potential temperature, thickness, water vapor, precipitation, and the influence of bottom topography. It calculates velocity fields in both the lower and upper troposphere, employing resolutions spanning a spectrum from the smooth to the coarse, enabling the exploration of a wide range of dynamic phenomena with varying levels of detail and precision.
