Formed by winds associated with cyclones, atmospheric rivers typically range from 250 miles to 375 miles (400 to 600 kilometers) in width and move under the influence of other weather. Many ...
An explanation from the National Weather Service on atmospheric rivers. An atmospheric river (AR) is a narrow corridor or filament of concentrated moisture in the atmosphere. Other names for this phenomenon are tropical plume, tropical connection, moisture plume, water vapor surge, and cloud band. [1] [2]
The term "atmospheric river" is a term first used in the 1990s to describe a plume of tropical moisture in the atmosphere that can result in heavy rainfall or snowfall. ... Weather. 24/7 Help. For ...
Meteoric water, derived from precipitation such as snow and rain, includes water from lakes, rivers, and ice melts, all of which indirectly originate from precipitation.. The journey of meteoric water from the atmosphere to the Earth's surface is a critical component of the hydrologic cyc
As rivers flow downstream, they eventually merge to form larger rivers. A river that feeds into another is a tributary, and the place they meet is a confluence. [4] Rivers must flow to lower altitudes due to gravity. [3] The bed of a river is typically within a river valley between hills or mountains.

Runoff is the flow of water across the earth, and is a major component in the hydrological cycle.Runoff that flows over land before reaching a watercourse is referred to as surface runoff or overland flow.
"California will be impacted by yet another atmospheric river this rainy season, delivering moisture to areas that have seen little of it this year," noted AccuWeather Meteorologist Jacob Hinson.
