“The North American monsoon is the period of rainfall and severe weather that occurs during the mid to late part of the summer in the Southwestern United States. The basic cause of the North American monsoon, like its cousin in India, is the thermal contrast between the land and ocean. Though certainly not as dramatic as India, the North American monsoon is associated with regular shifts in circulations, winds, and precipitation. Monsoon thunderstorms are initiated by mountain-valley circulations and follow a regular diurnal cycle. The most dramatic severe weather days are characterized by organized, propagating convection in association with upper-level disturbances. Severe weather hazards during the monsoon unique to the Southwest include flash flooding, debris flows, micro-bursts, haboobs (or dust storms), lightning, and wildfire.
Predictability of the monsoon is challenging, even for daily weather forecasts. High resolution numerical atmospheric models are required to explicitly resolve monsoon thunderstorms, and even the most sophisticated modeling tools will never be able to tell us with certainty if when and where storms will occur at an exact location. When thinking on longer timescales, there are some potential predictable factors which may govern monsoon seasonal rainfall, especially during the onset period. Monsoon precipitation is also likely changing in relation to anthropogenic climate change, with the changes generally conforming to a “wet gets wetter, dry gets drier” paradigm that is observed globally.”
