North American Monsoon
North America experiences a yearly monsoon weather system in late summer as moisture comes up from the west coast of Mexico and enters the southwestern U.S. The seasonal weather pattern brings both much of the region's precipitation but can also pose a threat in the form of flash flooding. The Global Precipitation Measurement (GPM) mission gathers data from these storms in order to better understand the precipitation processes happening within, which can help better forecast the breaks and surges in the monsoon.
