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 ...
A comparison of X-band polarization parameters with in-situ microphysical measurements in the comma head of two winter cyclones (2015-12-07)Since the advent of dual-polarization radar, methods of classifying hydrometeors by type from measured polarization variables have been developed. However, the deterministic approach of existing hydrometeor classification ...
Interaction of an upper-tropospheric jet with a squall line originating along a cold frontal boundary (2015-12-07)On 8 June 2003, an expansive squall line along a surface cold frontal boundary was sampled during the Bow Echo and Mesoscale Convective Vortex Experiment. The Naval Research Laboratory P-3 aircraft and the National Oceanic ...
(2015-07-20)The projected increase in global air traffic raises concerns about the potential impact aviation emissions have on climate and air quality. Previous studies have shown that aircraft cruise emissions (emitted between 9-11 ...
