How Do Models Make Clouds?
for more advanced readers

WHAT'S STILL NEEDED?

wxsystem These are some of the more popular ways to represent the effects of clouds on a grid cell. However, these schemes are far from complete representations of clouds. Cumulus clouds themselves are small, but they can be organized into large systems that span hundreds of miles like the NOAA GEOS satellite image here. Current cloud parameterizations do not take into account these large-scale motions.

Also, cumulus convection is linked to the Earth's boundary layer but the parameterizations often overlook this important connection.

Third, these parameterizations represent deep convection (what you would associate with a towering thunderstorm), but shallow convection is also very important to the Earth's weather and climate. Examples of shallow convection include the low clouds and fog common to the Californian coast. Clearly, there is still a lot of work that needs to be done in representing clouds in climate models. That is where CMMAP comes in!
