RISThe Moisture Mode in the Quasi-Equilibrium Tropical Circulation Model. Part II: Nonlinear Behavior on an Equatorial β Plane
Publisher: American Meteorological Society
Abstract: Numerical calculations of a simplified quasi-equilibrium tropical circulation model (QTCM) on the equatorial ? plane have been performed to explore the nonlinear regime of the moisture mode. Sensitivity tests have examined ...
The Moisture Mode in the Quasi-Equilibrium Tropical Circulation Model. Part I: Analysis Based on the Weak Temperature Gradient Approximation
Publisher: American Meteorological Society
Abstract: The moisture mode in a simplified version of the quasi-equilibrium tropical circulation model (QTCM) of Neelin and Zeng is analyzed. Perturbation expansion based on the ratio of temperature tendency to adiabatic cooling ...
Eastward-Propagating Intraseasonal Oscillation Represented by Chikira–Sugiyama Cumulus Parameterization. Part I: Comparison with Observation and Reanalysis
Publisher: American Meteorological Society
Abstract: he eastward-propagating intraseasonal oscillation represented by the Chikira?Sugiyama cumulus parameterization in an atmospheric general circulation model is compared with observations and reanalyses. The scheme is ...
A Cumulus Parameterization with State-Dependent Entrainment Rate. Part I: Description and Sensitivity to Temperature and Humidity Profiles
Publisher: American Meteorological Society
Abstract: A new cumulus parameterization is developed for which an entraining plume model is adopted. The lateral entrainment rate varies vertically depending on the surrounding environment. Two different formulations are examined ...
The Role of Relative Humidity in Radiative–Convective Equilibrium
Publisher: American Meteorological Society
Abstract: The following conditions are derived for the existence of a radiation limit of tropospheric origin in a nongray atmosphere, extending the work on a gray atmosphere by Nakajima et al.: 1) the atmosphere must become sufficiently ...
