The climate on the planet of Pandora is very similar to the climate found around the Earth's equator. The planet experiences very warm and humid temperatures throughout the entire year. The high level of humidity is a result of the warmer air masses that are present on Pandora. The warmer air is able to retain more moisture, causing the specific humidity to be approximately 20g/kg.

The warm weather along with the abundance of water on Pandora leads to one very important thing to sustain life on the planet...rain, and lots of it. Due to the rapid evaporation of the surface water, clouds in Pandora's atmosphere reach their dew point very quickly and very commonly. Cumulonimbus clouds develop and the storm systems build until the dew point has been reached and the convective precipitation falls in the form of rain. Pandora experiences higher levels or rainfall than anywhere else known to man kind, beating out Earth's tropical regions hands down.

Notice the nimbostratus and remaining cumulonimbus clouds

Pandora also is very well known for its fog. Almost like San Francisco, only a lot cooler and more alien-ish. The fog on Pandora however often times occurs at higher elevations than on Earth. This is because of the floating mountains. When the rain water evaporates off of the mountains radiation fog is formed, making the mountains look even more majestic.

Pandora is the perfect incubator for fog due to the large amount of rain |
Below is a picture of Pandora from space. You can clearly see the high and low pressure systems and the developing storm cells. It even looks like there is a developing hurricane, which I have circled. The warm waters and high humidity would make Pandora the essential location to study hurricanes, too bad it isn't real.
