RISDistinguishing Pronounced Droughts in the Southwestern United States: Seasonality and Effects of Warmer Temperatures
Publisher: American Meteorological Society
Abstract: Higher temperatures increase the moisture-holding capacity of the atmosphere and can lead to greater atmospheric demand for evapotranspiration, especially during warmer seasons of the year. Increases in precipitation or ...
Spatiotemporal Variability of Precipitation, Modeled Soil Moisture, and Vegetation Greenness in North America within the Recent Observational Record
Publisher: American Meteorological Society
Abstract: Dominant spatiotemporal patterns of precipitation, modeled soil moisture, and vegetation are determined in North America within the recent observational record (late twentieth century onward). These data are from a gridded ...
Improving Seasonal Predictions of Climate Variability and Water Availability at the Catchment Scale
Publisher: American Meteorological Society
Abstract: In a water-stressed region, such as the southwestern United States, it is essential to improve current seasonal hydroclimatic predictions. Typically, seasonal hydroclimatic predictions have been conditioned by standard ...
The Relationship of the North American Monsoon to Tropical and North Pacific Sea Surface Temperatures as Revealed by Observational Analyses
Publisher: American Meteorological Society
Abstract: The North American monsoon is a seasonal shift of upper- and low-level pressure and wind patterns that brings summertime moisture into the southwest United States and ends the late spring wet period in the Great Plains. ...
Atmospheric Rivers and Cool Season Extreme Precipitation Events in the Verde River Basin of Arizona
Publisher: American Meteorological Society
Abstract: nland-penetrating atmospheric rivers (ARs) can affect the southwestern United States and significantly contribute to cool season (November?March) precipitation. In this work, a climatological characterization of AR events ...
Investigation of the Summer Climate of the Contiguous United States and Mexico Using the Regional Atmospheric Modeling System (RAMS). Part I: Model Climatology (1950–2002)
Publisher: American Meteorological Society
Abstract: Fifty-three years of the NCEP?NCAR Reanalysis I are dynamically downscaled using the Regional Atmospheric Modeling System (RAMS) to generate a regional climate model (RCM) climatology of the contiguous United States and ...
Coupled Interannual Variability of Wind and Sea Surface Temperature in the Caribbean Sea and the Gulf of Mexico
Publisher: American Meteorological Society
Abstract: AbstractThis work describes dominant patterns of coupled interannual variability of the 10-m wind and sea surface temperature in the Caribbean Sea and the Gulf of Mexico (CS&GM) during the period 1982?2016. Using a canonical ...
The Relationship of Transient Upper-Level Troughs to Variability of the North American Monsoon System
Publisher: American Meteorological Society
Abstract: Relationships between transient upper-tropospheric troughs and warm season convective activity over the southwest United States and northern Mexico are explored. Analysis of geopotential height and vorticity fields from ...
An Improved QPE over Complex Terrain Employing Cloud-to-Ground Lightning Occurrences
Publisher: American Meteorological Society
Abstract: AbstractA lightning?precipitation relationship (LPR) is studied at high temporal and spatial resolution (5 min and 5 km). As a proof of concept of these methods, precipitation data are retrieved from the National Severe ...
A Modified Kain–Fritsch Scheme and Its Application for the Simulation of an Extreme Precipitation Event in Vietnam
Publisher: American Meteorological Society
Abstract: From 24 to 26 November 2004, an extreme heavy rainfall event occurred in the mountainous provinces of central Vietnam, resulting in severe flooding along local rivers. The Regional Atmospheric Modeling System, version 4.4, ...
