Even if the net rate of moisture exchange were to remain fixed, the Walker circulation could still become stronger or weaker, if the circulation reorganized itself to put less or more of the exchange in the form of small scale convective motions.
A traditional parametrisation scheme seeks to represent the average effect of the sub grid - scale motion (e.g. convective clouds) on the resolved scale state (e.g. the large scale temperature and wind fields).
Its convective strength — the boiling motion of air rising from the ocean surface to the atmosphere — depends on the temperature difference between the surface ocean and the upper atmosphere.
The ITCZ is formed by vertical motion largely appearing as convective activity of thunderstorms driven by solar heating, which effectively draw air in; these are the trade winds.
Even for smaller scales, except for the most vigorous convective motions, the dynamic pressure is still only a small fraction of the hydrostatic pressure.
Gravity is also opposed to outward convective motion of mass, limiting convective actions within their vertical velocities.
This sort of organized convective motion is a common feature of this sort of fluid system with heat flowing against gravity — the Rayleigh - Benard cell in particular.
A greater fraction of convective flux being in the form of latent heat would mean the same amount of motion with the same temperature distribution would tend to accomplish a greater convective heat flux.
In contrast, the small - scale convective motions have aspect ratios of order one.
