Stratus Clouds

www.weatherpictures.nl



Stratus clouds are quite boring uniform gray clouds that usually cover the entire sky. They can form when weak, upward vertical air currents lift a layer of air high enough to its condensation point. Stratus clouds also form when a layer of air is cooled from below to its dewpoint temperature and water vapor condenses into liquid droplets. Stratus clouds look like a layer of fog that never reaches the ground. In fact, fog that "lifts" off the ground forms a layer of low stratus clouds. Sometimes when there is too much wind at night in order to form fog, turbulation Stratus forms below a subsidence inversion in the atmosphere. Precipitation rarely falls from true stratus clouds since the upward vertical motion needed for precipitation is very weak, but light mist and drizzle can sometimes accompany stratus clouds.
When a frontal system passes, low Stratus clouds can also be seen. Often these clouds are accompanied by precipitation, resulting in Nimbostratus.
