RISHurricane Alley SST Variability in 2005 and 2006
Publisher: American Meteorological Society
Abstract: The North Atlantic hurricane seasons of 2005 and 2006 were dramatically different for the Gulf Coast and eastern seaboard of the United States. The 2005 hurricane season was one of the most destructive seasons in history, ...
Comments on “Characterizing ENSO Coupled Variability and Its Impact on North American Seasonal Precipitation and Temperature”
Publisher: American Meteorological Society
Abstract: AbstractEl Niño and La Niña seasonal weather anomaly associations provide a useful basis for winter forecasting over the North American regions where they are sufficiently strong in amplitude and consistent in character ...
El Niño Impacts on Seasonal U.S. Atmospheric Circulation, Temperature, and Precipitation Anomalies: The OLR-Event Perspective
Publisher: American Meteorological Society
Abstract: his study shows that, since 1979 when outgoing longwave radiation (OLR) observations became reliably available, most of the useful U.S. seasonal weather impact of El Niño events is associated with the few events identified ...
Simulating ENSO SSTAs from TAO/TRITON Winds: The Impacts of 20 Years of Buoy Observations in the Pacific Waveguide and Comparison with Reanalysis Products
Publisher: American Meteorological Society
Abstract: he fundamental importance of near-equatorial zonal wind stress in the evolution of the tropical Pacific Ocean?s seasonal cycle and El Niño?Southern Oscillation (ENSO) events is well known. It has been two decades since the ...
Observed El Niño SSTA Development and the Effects of Easterly and Westerly Wind Events in 2014/15
Publisher: American Meteorological Society
Abstract: he unexpected halt of warm sea surface temperature anomaly (SSTA) growth in 2014 and development of a major El Niño in 2015 has drawn attention to our ability to understand and predict El Niño development. Wind stress?forced ...
Tropical Pacific Surface Wind Energy Spectra and Coherence: Basinwide Observations and Their Observing System Implications
Publisher: American Meteorological Society
Abstract: The tropical Pacific moored-buoy array spacing was based on wind coherence scales observed from low-lying islands in the western-central tropical Pacific. Since the array was deployed across the full basin in the mid-1990s, ...
Global Seasonal Precipitation Anomalies Robustly Associated with El Niño and La Niña Events—An OLR Perspective
Publisher: American Meteorological Society
Abstract: l Niño?Southern Oscillation (ENSO) events are associated with particular seasonal weather anomalies in many regions around the planet. When the statistical links are sufficiently strong, ENSO state information can provide ...
Equatorial Pacific Easterly Wind Surges and the Onset of La Niña Events
Publisher: American Meteorological Society
Abstract: he processes responsible for the onset of La Niña events have not received the same attention as those responsible for the onset of El Niño events, for which westerly wind events (WWEs) in the tropical Pacific have been ...
Subseasonal Atmospheric Variability and El Niño Waveguide Warming: Observed Effects of the Madden–Julian Oscillation and Westerly Wind Events
Publisher: American Meteorological Society
Abstract: esterly wind events (WWEs) have previously been shown to initiate equatorial Pacific waveguide warming. The relationship between WWEs and Madden?Julian oscillation (MJO) activity, as well as the role of MJO events in ...
Summertime Rainfall Events in Eastern Washington and Oregon
Publisher: American Meteorological Society
Abstract: he temporal and spatial characteristics of summertime rainfall events in the Pacific Northwest are examined in relation to the prevailing regional 500-hPa geopotential height conditions, with focus on the forested slopes ...
