A monsoon (/ m ɒ n ˈ s uː n /) is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation [1] but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator.
A monsoon is a shift in seasonal wind pattern that brings on a very rainy period. In the U.S., the desert southwest, the summer monsoon season usually begins around mid-June .

The North American monsoon is a complex weather process that brings moisture from the Gulf of California (and to lesser extent the eastern Pacific and Gulf of Mexico) over northwestern Mexico and southwestern US resulting in summer thunderstorms, especially at higher elevations.

The Australian monsoon can also have a high influence on rainfall on the southeastern seaboard during the warmer months, such as in southeast Queensland and as well as the northern half of New South Wales (Northern Rivers to metropolitan Sydney), where summer is the wettest season and winter is the driest (the precipitation contrast between the ...
As an annual weather pattern known as the North American monsoon continues to bring much-needed rain to the southwestern United States, moisture is forecast to expand over the West and bring the ...
