ARkStorm is a USGS led project to model the impacts of a catastrophic flood event in California.
The term “Atmospheric River” is used to explain the moist conveyor belt associated with Pacific storms. Also known as the “pineapple express.”

Increase in the amount of daily precipitation over North America that falls in heavy events
Increase in precipitation intensity is consistent with the observed increases in atmospheric water vapor
![Page 20: NOAA: Storms and Drought: Climate Change Impacts on the West · 11/14/2011 · WISPAR – Winter Storms and Pacific Atmospheric Rivers project measured water vapor content from approaching](https://reader033.fdocuments.in/reader033/viewer/2022050509/5f99fc36038f2c74111d6e09/html5/thumbnails/20.jpg)
Precipitation intensity is a key component of severe weather.
Flash floods, debris flows, and snowfall intensity can be very destructive and life-threatening.

Winter storm tracks are shifting northward and the strongest storms are likely to become stronger and more frequent,
with greater wind speeds and more extreme wave heights.

There is no clear trend in the frequency or strength of tornadoes
since the 1950s for the United States as a whole...
...however, the frequency of favorable conditions for severe
