Parameterizing deep convection using the assumed probability density function method
Parameterizing deep convection function method
2015/3/5
Due to their coarse horizontal resolution, presentday climate models must parameterize deep convection. This
paper presents single-column simulations of deep convection
using a probability density f...
Influence of the Ringwoodite-Perovskite transition on mantle convection in spherical geometry as a function of Clapeyron slope and Rayleigh number
