Nimbostratus Clouds Next Topic: Precipitation

A nimbostratus cloud is similar to a stratus cloud in its formless, smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud, because it is thicker.

Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat of moderate to heavy precipitation. In some cases, the precipitation may evaporate before reaching the ground, a phenomenon known as virga.

Rain Next Topic: Shelf Clouds

Precipitation in the form of water droplets is called rain. Rain generally has a tendency to fall with less intensity over a greater period of time, and when rainfall is more severe it is usually less sustained.

Rain is the most common form of precipitation and happens with greater frequency depending on the season and regional influences. Cities have been shown to have an observable effect on rainfall, due to an effect called the urban heat island. Compared to upwind, monthly rainfall between twenty and forty miles downwind of cities is 30% greater.
