According to the National Weather Service: A monsoon is generally defined as a seasonal variation of wind, cloud cover and precipitation that is controlled by the annual cycle of the sun. In climates that are strongly influenced by monsoons, most of the annual precipitation is received during the monsoon season. Portions of the southwest United States, including New Mexico, are influenced by the North American Monsoon System (NAMS), which is also referred to as the Southwest Monsoon. Many locations in New Mexico receive 40 to 50 percent of the annual precipitation during the period from July 1 through August 31 and much, but not all, of the summer rainfall can be attributed to the Southwest Monsoon.
I'm a little late with my monsoon cloud photos, but these are pretty much what we see in the afternoons in eastern New Mexico during the monsoon season (even though these photos were taken in September). Our mornings often bring us clear blue skies, but once we pass noon, the crystal ships come sailing in from the south and the west.
Umbrella man come
Quick, quick, quick,
The monsoon rain is here.
The rain is finally here.
