Atmospheric Rivers in the News

The topic of atmospheric rivers, a phenomenon that has been a focus of HMT-West activities, has been in the news lately, both as stories on NOAA's home page, in the print media and on key blogs. This interest and outreach represents a growing awareness of the role of atmospheric rivers in weather and climate, specifically in terms of precipitation, flooding, and the global water cycle.

Recent Stories (January-February 2011)

The public interest has emerged partly as a result of the convergence of several key events and activities:
