Abstract Low-level stratiform clouds modulate California's coastal climate during the warm season. Previous work describing the seasonal and daily variability of coastal low cloudiness (CLC) suggests that in July, August, and September southern California's CLC is under the influence of an additional driver, which has less impact in northern California. In this work, we introduce the link in which free-tropospheric moisture dictated by North American Monsoon (NAM) processes can impact southern California CLC. We use in situ and remote sensing observations, as well as reanalysis and single column model simulations to identify and investigate this previously missing component. We find that monsoonal moisture advected...

The Colorado River provides water to 40 million people in the southwestern United States. Consistent water level declines in Colorado River Basin reservoirs have focused research attention on the long-term changes in winter precipitation and the timing of snowmelt and runoff. Research on how warming temperatures affect winter precipitation and spring snowmelt is ongoing, however, less attention has been given to changes in spring and summer precipitation which also affects water supply, plant growth, and competition between native and non-native plants, and, in turn affects wildfire dynamics and wildlife habitat. The amount and timing of summer precipitation is largely influenced by variation in the North American...
