RISA Climatology of the Tropospheric Thermal Stratification Using Saturation Potential Vorticity
Publisher: American Meteorological Society
Abstract: The condition of convective neutrality is assessed in the troposphere by calculating the saturation potential vorticity P* from reanalysis data. Regions of the atmosphere in which saturation entropy is constant along ...
The Global Atmospheric Circulation in Moist Isentropic Coordinates
Publisher: American Meteorological Society
Abstract: Differential heating of the earth?s atmosphere drives a global circulation that transports energy from the tropical regions to higher latitudes. Because of the turbulent nature of the flow, any description of a ?mean ...
The Dynamic Response of the Winter Stratosphere to an Equable Climate Surface Temperature Gradient
Publisher: American Meteorological Society
Abstract: This work investigates the dynamic and thermal response of the winter stratosphere to the presence of a weak meridional surface temperature gradient. Previous work suggested that polar stratospheric clouds could have played ...
Tropical Cyclone Genesis Factors in a Simulation of the Last Two Millennia: Results from the Community Earth System Model
Publisher: American Meteorological Society
Abstract: sing a coupled global climate model, Community Earth System Model (CESM), the authors investigate the response of tropical cyclone (TC) genesis factors (i.e., potential intensity, vertical wind shear, midtropospheric ...
Impact of Varying the Number of Heat Exchangers Used in the Latent Heat Thermal Energy Storage Unit on the Thermal Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Latent heat thermal energy storage is one of the most relevant methods allowing to provide a solution of the energy supply–demand dilemma. A novel structure of latent heat thermal energy storage (LHTES) unit is designed ...
Tropical Cyclone–Induced Upper-Ocean Mixing and Climate: Application to Equable Climates
Publisher: American Meteorological Society
Abstract: Tropical cyclones instigate an isolated blast of vigorous mixing in the upper tropical oceans, stirring warm surface water with cooler water in the thermocline. Previous work suggests that the frequency, intensity, and ...
Variations in Tropical Cyclone Genesis Factors in Simulations of the Holocene Epoch
Publisher: American Meteorological Society
Abstract: he thermodynamic factors related to tropical cyclone genesis are examined in several simulations of the middle part of the Holocene epoch when the precession of Earth?s orbit altered the seasonal distribution of solar ...
Tropical Cyclone Genesis Factors in Simulations of the Last Glacial Maximum
Publisher: American Meteorological Society
Abstract: arge-scale environmental factors that favor tropical cyclogenesis are calculated and examined in simulations of the Last Glacial Maximum (LGM) from the Paleoclimate Modelling Intercomparison Project Phase 2 (PMIP2). Despite ...
Evaluation of 33 Years of Quantitative Precipitation Forecasting at the NMC
Publisher: American Meteorological Society
Abstract: The National Meteorological Center (NMC) initiated Quantitative Precipitation Forecasts (QPF) and an intensive QPF verification program in 1960. These forecast products have evolved from a manual effort, relying on extensive ...
Environmental Control of Tropical Cyclone Intensity
Publisher: American Meteorological Society
Abstract: The influence of various environmental factors on tropical cyclone intensity is explored using a simple coupled ocean?atmosphere model. It is first demonstrated that this model is capable of accurately replicating the ...
