QUICK GUIDE

IWV and IVT

Atmospheric-river analysis combines the amount of atmospheric moisture with the strength of its transport.

IWV

Integrated Water Vapor: the total amount of water vapor through the atmospheric column.

IVT

Integrated Vapor Transport: combines moisture with wind to identify concentrated moisture transport.

Satellite

Water-vapor and infrared imagery reveal cloud structure and the larger moisture environment.

AR Detection

Detection algorithms identify long, narrow corridors of enhanced atmospheric moisture transport.
