Computer Modeling Shows Where Arizona’s Winter Precipitation Originates

The Sun Corridor in Arizona in the semi-arid Southwestern U.S. is a land of seemingly unlimited growth that is constantly colliding with physical constraints.

The Sun Corridor in Arizona in the semi-arid Southwestern U.S. is a land of seemingly unlimited growth that is constantly colliding with physical constraints. It is mountainous but also home to a large valley that includes one of the fastest growing metropolitan areas in the U.S.

While experiencing explosive growth, the Phoenix metropolitan area faces an uncertain future due to prolonged drought and fluctuating seasonal water availability. Planning for the future, especially in terms of water, has long been both a challenge and a staple of life in Arizona.

Now, a team of researchers including scientists from Arizona State University are working with a weather model to uncover new details of water availability in Arizona’s uplands and where that water comes from. The work may help in future planning of the Phoenix metropolitan area, as well as provide guides for coming precipitation seasons.
