Scales of Linear Baroclinic Instability and Macroturbulence in Dry Atmospheres
Publisher: American Meteorological Society
Abstract: Linear stability analyses are performed on a wide range of mean flows simulated with a dry idealized general circulation model. The zonal length scale of the linearly most unstable waves is similar to the Rossby radius. ...
The Role of the Nonlinearity of the Stefan–Boltzmann Law on the Structure of Radiatively Forced Temperature Change
Publisher: American Meteorological Society
Abstract: The Stefan?Boltzmann law governs the temperature dependence of the blackbody emission of radiation: . A consequence of this nonlinearity is that a cold object needs a greater increase in temperature than a hot object in ...
Changes in Zonal Surface Temperature Gradients and Walker Circulations in a Wide Range of Climates
Publisher: American Meteorological Society
Abstract: ariations in zonal surface temperature gradients and zonally asymmetric tropical overturning circulations (Walker circulations) are examined over a wide range of climates simulated with an idealized atmospheric general ...
The Observed Relationship between Pacific SST Variability and Hadley Cell Extent Trends in Reanalyses
Publisher: American Meteorological Society
Simple Estimates of Polar Amplification in Moist Diffusive Energy Balance Models
Publisher: American Meteorological Society
Abstract: AbstractDiffusive energy balance models (EBMs) that use moist static energy, rather than temperature, as the thermodynamic variable to determine the energy transport provide an idealized framework to understand the pattern ...
Coupled High-Latitude Climate Feedbacks and Their Impact on Atmospheric Heat Transport
Publisher: American Meteorological Society
Abstract: AbstractThe response of atmospheric heat transport to anthropogenic warming is determined by the anomalous meridional energy gradient. Feedback analysis offers a characterization of that gradient and hence reveals how ...
Evaluating the Evidence of a Global Sea Surface Temperature Threshold for Tropical Cyclone Genesis
Publisher: American Meteorological Society
Abstract: AbstractRecent studies have reaffirmed a global threshold sea surface temperature (SST) of 26°C for tropical cyclone (TC) genesis. However, it is well understood that other thermodynamic variables influence TC genesis and ...
