RISFactors Associated with Decadal Variability in Great Plains Summertime Surface Temperatures
Publisher: American Meteorological Society
Abstract: ecadal variability of summertime Great Plains surface temperature is probed from the perspective of the Great Plains low-level jet (GPLLJ). GPLLJ variability modes 2 and 5 are shown to be most influential on the evolution ...
Variability of the Great Plains Low-Level Jet: Large-Scale Circulation Context and Hydroclimate Impacts
Publisher: American Meteorological Society
Abstract: Variability of the Great Plains low-level jet (GPLLJ) is analyzed from the perspective of larger-scale, lower-frequency influences and regional hydroclimate impacts as opposed to the usual analysis of its frequency, diurnal ...
Recurrent Supersynoptic Evolution of the Great Plains Low-Level Jet
Publisher: American Meteorological Society
Abstract: The evolution of supersynoptic (i.e., pentad) Great Plains low-level jet (GPLLJ) variability, its precipitation impacts, and large-scale circulation context are analyzed in the North American Regional Reanalysis (NARR)?a ...
Warm Season Variations in the Low-Level Circulation and Precipitation over the Central United States in Observations, AMIP Simulations, and Idealized SST Experiments
Publisher: American Meteorological Society
Abstract: Sea surface temperature (SST) linkages to central U.S. low-level circulation and precipitation variability are investigated from the perspective of the Great Plains low-level jet (GPLLJ) and recurring modes of SST variability. ...
Climatic Role of North American Low-Level Jets on U.S. Regional Tornado Activity
Publisher: American Meteorological Society
Abstract: ariability of springtime tornadic activity over the United States is assessed through the connectivity of preferred modes of North American low-level jet (NALLJ) variability to the local thermodynamic environment and remote ...
Pentad Evolution of the 1988 Drought and 1993 Flood over the Great Plains: An NARR Perspective on the Atmospheric and Terrestrial Water Balance
Publisher: American Meteorological Society
Abstract: The evolution of the atmospheric and land surface states during extreme hydroclimate episodes over North America is investigated using the North American Regional Reanalysis (NARR), which additionally, and successfully, ...
Pentad Evolution of Wintertime Impacts of the Madden–Julian Oscillation over the Contiguous United States
Publisher: American Meteorological Society
Abstract: agged pentad composites of surface air temperature and precipitation are analyzed for the winter season (December?February) to assess the influence of the Madden?Julian oscillation (MJO) on the climate of the contiguous ...
Low-Level Jets over the Mid-Atlantic States: Warm-Season Climatology and a Case Study
Publisher: American Meteorological Society
Abstract: Although considerable research has been conducted to study the characteristics of the low-level jets (LLJs) over the Great Plains states, little is known about the development of LLJs over the Mid-Atlantic states. In this ...
Representation of MJO Variability in the NCEP Climate Forecast System
Publisher: American Meteorological Society
Abstract: he Madden?Julian oscillation (MJO) is arguably the most important intraseasonal mode of climate variability, given its significant modulation of global climate variations and attendant societal impacts. Advancing the current ...
