= Atmospheric river
{wiki=Atmospheric_river}
An atmospheric river is a narrow, elongated corridor of concentrated moisture in the atmosphere. These phenomena can transport large amounts of water vapor from tropical regions toward higher latitudes, particularly affecting coastal areas. The water vapor can then condense and fall as precipitation, leading to significant rainfall or snowfall when the moist air is lifted over mountains or cooler regions. Atmospheric rivers can vary in intensity and duration and are categorized into different levels based on their impact.
