Moisture transport associated with the summertime North American monsoon.
… semi-arid Sonoran Desert region of southwestern North America are examined for the July-August wet season. Vertically-integrated fluxes and flux divergences of water vapor are computed for the 8 summers, 1985-1992, from ECMWF mandatory-level analyses possessing a spectral resolution of triangular …

An origin of North American monsoon retreat biases in climate models
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-08-01

North American monsoon precipitation and its precursors: processes at the seasonal and diurnal scale
… and 10~km resolution for the 2000 and 2004 monsoon seasons (July-September), a dry year and a wet year. These years were chosen to represent contrasting precipitation outcomes to assure that results were robust across different monsoon conditions. Model precipitation was compared to …

Seasonal Influences on the Carbon-Water Relations in Ponderosa Pine Forests in the Northern Boundary of the North American Monsoon System
… by a complex climatology related to the North American Monsoon system (NAMS). A topic of interest in this dissertation is the role of the summer rainfall after the early-summer hyper-arid period in the region, providing a unique seasonal condition for these ecosystems to thrive. While …

Glacial-Interglacial Variability of Eastern Pacific Hydroclimate
Unprecedented drought conditions in southwest North America (SWNA, defined as the region from southern California to southern Mexico, west of the continental divide) has raised alarms regarding water resource scarcity in a region with dense urban populations and vital agricultural industries. …

Variation in the Bimodal Precipitation Regime of Southern Nevada, USA Measured in Tree-Ring Isotopes
The North American Monsoon System (NAMS) is a seasonal climatic phenomenon vital to ecosystems and human population centers in the southwestern USA and northwestern Mexico. Inter-annual variation of the NAMS bimodal precipitation regime is more predictable in its core region of northwestern Mexico, …

Eco-hydrological pathways inferred from stable isotopes in a Pinus ponderosa and Pinus monophylla woodland of the Sheep Range, southern Great Basin, USA
The North American Monsoon System (NAMS) is highly variable bothtemporally and spatially, and variability is likely to increase with climate change. The impact of summer precipitation on ecosystem patterns and processes, particularly at high elevations in the Great Basin, is poorly understood. In …

Integrating urban heat island influences into statistically downscaled climate projections in the Truckee Meadows, Nevada
… A synoptic climatology indicated that the North American Monsoon may provide favorable conditions for UHI development during the summer. Several methods for downscaling future temperature projections for the Truckee Meadows produced by global climate model data under three IPCC emissions …

Improving Convective Permitting Model Simulations of Extreme Precipitation using Object-Based Tracking and Data Assimilation
… In Appendix B, we move our attention to the North American Monsoon (NAM) that takes place in Arizona, and we present an Observing System Simulation Experiment (OSSE) framework to test the impact of assimilating GPS-derived Precipitable Water Vapor (PWV) using different densities of …

Examining Atmospheric and Ecological Drivers of Wildfires, Modeling Wildfire Occurrence in the Southwest United States, and Using Atmospheric Sounding Observations to Verify National Weather Service Spot Forecasts
… The rainfall and lightning associated with the North American Monsoon (NAM) can vary greatly intra- and inter-annually and has a large impact on wildfire activity across the SWA by igniting or suppressing wildfires. NAM onset thresholds and subsequent dates are determined for the SWA and each …

CWRF summer precipitation prediction over the United States land and coastal oceans: effects of ensemble cumulus parameterization closures
… distribution, but produces wet biases over the North American Monsoon (NAM) region and Southeast U.S. which can be significantly reduced by using the W closure. Further skill enhancement can be made using an optimized ensemble of the MC and W closures. The TD and KF closures show advantages in …
