Detecting atmospheric rivers with satellite observations

Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a challenging task due to the lack of wind information. In a study published in the Journal of Geophysical Research: Atmospheres, scientists derived an approximation of the 3-dimensional (3D) wind field based on the spatial distribution of the satellite-based temperature.
