The nonlinear downstream development of baroclinic instability
The downstream development in both space and time of baroclinic instability is studied in a nonlinear channel model on the f -plane. The model allows the development of the instability to be expressed on space and time scales that are long compared to the growth rates and wavelengths of the most unstable wave. The unstable system is forced by time-varying boundary conditions at the origin of th...
متن کاملTransient moist baroclinic instability
The non-modal transient properties of the Eady baroclinic model with a simple heating parameterization are examined. The time-dependent non-modal behavior of the moist baroclinic model is investigated by calculating the energy amplification of optimal perturbations for relevant time-scales and by calculating the energy evolution of random initial conditions. Enhanced non-modal growth on time-sc...
متن کاملthe impact of morphological awareness on the vocabulary development of the iranian efl students
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
15 صفحه اولBaroclinic Instability and Loss of Balance
Under the influences of stable density stratification and Earth’s rotation, large-scale flows in the ocean and atmosphere have a mainly balanced dynamics— sometimes called the slow manifold—in the sense that there are diagnostic hydrostatic and gradient-wind momentum balances that constrain the fluid acceleration. The nonlinear Balance Equations are a widely successful, approximate model for th...
متن کاملThe influence of stratospheric potential vorticity on baroclinic instability
This article examines the dynamical coupling between the stratosphere and troposphere by considering the effect of direct perturbations to stratospheric potential vorticity on the evolution of midlatitude baroclinic instability in a simple extension of an Eady model. A simulation in which stratospheric potential vorticity is exactly zero is used as a control case, and both zonally symmetric and...
