A knowledge of radiative convective interactions is key to an understanding of the tropical climate. In an attempt to address this a cloud‐resolving model has been run to a radiative‐convective equilibrium state in three dimensions. The model includes a three‐phase bulk microphysical scheme and a fully interactive two‐stream broadband radiative‐transfer scheme for both the infrared and solar radiation. The simulation is performed using a fixed sea surface temperature, and cyclic lateral boundary conditions. No ‘large‐scale’ convergence, mean wind shear or background vorticity was imposed.

The total integration lasted 70 days, and a statistical equilibrium state was reached at all heights after 30 days of simulation in all model variables. It is seen that some variables, such as vertical mass flux, adjust quickly to their equilibrium values while others, such as column‐integrated water amount, domain‐mean …
