During the wet season (October to March), cloud cover is more frequent and can range from scattered to overcast. The most common cloud types observed in Catalao include cumulus, stratus, and cirrus clouds.

Cirrus clouds are thin, wispy clouds that are composed of ice crystals and are typically associated with fair weather.

Cloud Formation and Precipitation

Clouds form in Catalao when warm, moist air rises and cools. As the air rises, it expands and cools, causing water vapor to condense into tiny water droplets or ice crystals. These droplets or crystals then collide with each other and grow in size, eventually becoming visible as clouds. Precipitation occurs when the water droplets or ice crystals in clouds become too heavy and fall to the ground. The type of precipitation that occurs depends on the temperature of the air and the surface it falls on. In Catalao, rain is the most common form of precipitation, but snow and hail can also occur during the winter months.
