Explanation:
1. Arizona and Utah are in the southwest region of the country and have a semi-arid to the arid climate. The area is renowned for having hot summers and pleasant winters, with temperature variations depending largely on location and altitude.
The "North American Monsoon," is a high-pressure system that frequently affects the region during the summer. The Pacific Ocean and the Gulf of Mexico both contribute moisture to this weather system, which causes thunderstorms and heavy rainfall in some locations. Nonetheless, the area frequently experiences high pressure during the winter, which usually brings about the clear sky and dry conditions.
