RISClimatic Variability of Near-Surface Turbulent Kinetic Energy over the United States: Implications for Fire-Weather Predictions
Publisher: American Meteorological Society
Abstract: ecent research suggests that high levels of ambient near-surface atmospheric turbulence are often associated with rapid and sometimes erratic wildland fire spread that may eventually lead to large burn areas. Previous ...
The Effect of Lake Temperatures and Emissions on Ozone Exposure in the Western Great Lakes Region
Publisher: American Meteorological Society
Abstract: A meteorological?chemical model with a 12-km horizontal grid spacing was used to simulate the evolution of ozone over the western Great Lakes region during a 30-day period in the summer of 1999. Lake temperatures in the ...
Temporal and Spatial Variability of Wind Resources in the United States as Derived from the Climate Forecast System Reanalysis
Publisher: American Meteorological Society
Abstract: his study examines the spatial and temporal variability of wind speed at 80 m above ground (the average hub height of most modern wind turbines) in the contiguous United States using Climate Forecast System Reanalysis ...
Evaluation of the Ventilation Index in Complex Terrain: A Dispersion Modeling Study
Publisher: American Meteorological Society
Abstract: AbstractIn this study, the Flexible Particle (FLEXPART)-WRF, a Lagrangian particle dispersion model, is employed to simulate pollutant dispersion in and near the Lehigh Gap, a gap in a prominent ridgeline in eastern ...
A Numerical Study of Smoke Concentration Distribution near Low-Intensity Fires: Sensitivity to Vertical Canopy Structure and Fire Heat Source Strength
Publisher: American Meteorological Society
Observations of Sweep–Ejection Dynamics for Heat and Momentum Fluxes during Wildland Fires in Forested and Grassland Environments
Publisher: American Meteorological Society
Mean and Turbulent Flow Downstream of a Low-Intensity Fire: Influence of Canopy and Background Atmospheric Conditions
Publisher: American Meteorological Society
Abstract: his study examines the sensitivity of mean and turbulent flow in the planetary boundary layer and roughness sublayer to a low-intensity fire and evaluates whether the sensitivity is dependent on canopy and background ...
The Interannual Variability of the Haines Index over North America
Publisher: American Meteorological Society
Abstract: he Haines index (HI) is a fire-weather index that is widely used as an indicator of the potential for dry, low-static-stability air in the lower atmosphere to contribute to erratic fire behavior or large fire growth. This ...
Will Future Climate Favor More Erratic Wildfires in the Western United States?
Publisher: American Meteorological Society
Abstract: ildfires that occurred over the western United States during August 2012 were fewer in number but larger in size when compared with all other Augusts in the twenty-first century. This unique characteristic, along with the ...
WRF Model Sensitivity to Land Surface Model and Cumulus Parameterization under Short-Term Climate Extremes over the Southern Great Plains of the United States
Publisher: American Meteorological Society
Abstract: xtreme weather and climate events, especially short-term excessive drought and wet periods over agricultural areas, have received increased attention. The Southern Great Plains (SGP) is one of the largest agricultural ...
