(2016-12-07)The semi-arid Salt and Verde River basins in Arizona depend, in part, on Atmospheric River (AR)-related precipitation for meeting the water demands of the Phoenix metropolitan area. On the other hand, the region is also ...
Analyzing the effects of unforced natural variability and anthropogenic forcing on ENSO variability using CESM (2016-12-05)The El Niño-Southern Oscillation (ENSO) is an important contributor to Earth’s inter-annual climate variability, with worldwide weather effects (Whetton and Rutherfurd, 1994; Hoerling and Zhong, 1997; Dai and Wigley, 2000). ...
Source air feeding convection within a nocturnal mesoscale convective system during the evolution from surface-based to elevated convection (2016-09-06)Although nocturnal convection is frequently observed, the mechanisms that allow nocturnal mesoscale convective systems (MCSs) to persist are still not well understood. On 9 August 2014 at approximately 2000 UTC, a regime ...
Investigating the link between Arctic sea ice, North Pacific geopotential height anomalies, and precipitation across the United States (2015-07-17)New evidence is presented to show that decreasing sea ice in the Arctic is causing an increased amplification of the jet stream off the west coast of the United States. We find a statistically significant relationship ...
(2015-12-11)This study examines the role that buoyancy and vertical wind shear play in modulating the relationship between storm interactions and storm severity. Using an idealized numerical model, 240 supercell interactions are ...
