Global-mean Vertical Tracer Mixing in Planetary Atmospheres II: Tidally Locked Planets
Xi Zhang, Adam P. Showman
In Zhang Showman (2018, hereafter Paper I), we developed an analytical theory of 1D eddy diffusivity for global-mean vertical tracer transport in a 3D atmosphere. We…
Atmospheric Circulation of Brown Dwarfs and Jupiter and Saturn-like Planets: Zonal Jets, Long-term Variability, and QBO-type Oscillations
Adam P. Showman, Xianyu Tan, Xi Zhang
Brown dwarfs and directly imaged giant planets exhibit significant evidence for active atmospheric circulation, which induces a large-scale patchiness in the cloud structure that e…
A High-performance Atmospheric Radiation Package: with applications to the radiative energy budgets of giant planets
Cheng Li, Tianhao Le, Xi Zhang +1
A High-performance Atmospheric Radiation Package (HARP) is developed for studying multiple-scattering planetary atmospheres. HARP is an open-source program written in C++ that util…
Formation of Silicate and Titanium Clouds on Hot Jupiters
Diana Powell, Xi Zhang, Peter Gao +1
We present the first application of a bin-scheme microphysical and vertical transport model to determine the size distribution of titanium and silicate cloud particles in the atmos…
Global-mean Vertical Tracer Mixing in Planetary Atmospheres I: Theory and Fast-rotating Planets
Xi Zhang, Adam P. Showman
Most chemistry and cloud formation models for planetary atmospheres adopt a one-dimensional (1D) diffusion approach to approximate the global-mean vertical tracer transport. The ph…
