Baroclinic instability draws energy from the portion of the potential energy available to be converted (referred to as ‘available potential energy’ or APE).

APE is dependent upon a horizontal gradient of temperature. The conversions of energy are proportional to perturbation heat fluxes in the horizontal and vertical. Energy Transformations and Meridional Circulations associated with simple Baroclinic Waves in a two-level, Quasi-geostrophic Model.

By Kelvin Wayne Huehn. The rate of kinetic energy change increases as larger values of thermal wind are selected, and for the adiabatic model the wave length range for which energy changes occur also expands with increasing thermal wind.

The energy gain initially is a maximum when the thermal wave lags Author: Kelvin Wayne Huehn. Abstract. Baroclinic and barotropic instabilities are well known as the mechanisms responsible for the production of the dominant energy-containing eddies in the atmospheres of Earth and several other planets, as well as Earth's oceans.

Here we consider insights provided by both linear and nonlinear instability theories into the conditions under which such instabilities may Cited by: 2.

In Figure 2 and Figure 3 we show the evolution of th e energy and ex change different model biases and resolutions, and the different data assimilation methods used by the respective.

Baroclinic instability of a flow with a constant vertical shear in a zonal channel has been studied. The maximally truncated SQG model was used to describe the dynamics of flow disturbances.

A dynami. An example of the interplay between barotropic and baroclinic instabilities is the barotropic governor.

This mechanism was first introduced by James and Gray () to explain why atmospheric simulations with the same baroclinicity but larger barotropic shears have smaller eddy kinetic energy.

James () presented both linear and nonlinear characteristics. Using simulations as in MS13, we employ the concept of baroclinic mean available potential energy (MAPE) to explore and help explain the storm-track shifts seen in this idealized dry ential large-scale radiative forcing generates MAPE, which midlatitude eddies convert into eddy available potential energy (EAPE) and eddy kinetic energy (EKE), primarily through baroclinic.

Schneider et al. (e.g., Schneider ; Schneider and Walker ) pointed out that in dry primitive equations models the heat vertically redistributed by the baroclinic eddies can reequilibrate the system by lifting the tropopause so that the atmosphere remains in a state of weak eddy–eddy interaction where the inverse energy cascade becomes inhibited.

The choice of identifying the baro- clinic two-layer-model energy with the energy in the first baroclinic mode gives two sufficient conditions for calibration: egH1 (H -- H1) f2oH = 1/ 1 = Rd21 (a) and: |/H-- H1 V ~ = FI(0) (b) We have summarized the characteristics of this calibration (and the others which we shall introduce later.

The energy radiation of the baroclinic tide is locally enhanced even in the generally weakened state, indicating that the energy radiation of the baroclinic tide is not simply governed by BEC variation but also is affected by the local dissipation and advection inside of the spot [Pereira et al., ; Chavanne et al., ; Jan et al., ].

Energy is absorbed to break bonds and released when bonds are made. Energy changes in a reaction are calculated by bond energies and shown by energy g: baroclinic.

It is found that baroclinic coupling increases modeled energy across the entire frequency spectrum, which is more commensurate with observations. In particular, density‐driven effects such as the seasonal cycle and sea level setdown due to trailing cold wakes from passing hurricanes are largely reproduced.

First, we present evidence from the global Hybrid Coordinate Ocean Model (HYCOM; Bleck ; Arbic et al. ) that the Gulf Stream (and other baroclinic jets, by analogy) can strongly refract and/or trap internal tide energy.

We then explain this using a new combination of mode and ray analysis methods. Depth-integrated baroclinic tidal energy flux (EF), its divergence, and topographic energy conversion (TEC) from the barotropic to baroclinic tide are computed from high-pass-filtered, harmonically analyzed model results in a series of day time windows.

Model results reveal several “hot spots” of intensive TEC on the slope. The ocean model is an extension of the Cane and Zebiak model including three vertical baroclinic modes. The values for phase speed (C n) and projection coefficient (P n) before and after the late s are derived from the vertical mode decomposition of a mean density profile along the equator (Table 1).

For stratification with two thermoclines, the ISW phase speed increases but the half-width decreases. In addition, the ratio of baroclinic to barotropic energy is found to be between 10% and 40%, and the ratio of ISW KE to APE is between and   The vertical velocity variance is significantly larger in the global model, except in the sheltered Southern California Bight.

While the regional model has roughly equal high‐pass baroclinic and barotropic kinetic energy levels, the global model high‐pass baroclinic kinetic energy is 28% ( PJ) greater than the barotropic energy. Abstract: This article reviews the energy cycle of the global ocean circulation, focusing on the role of baroclinic mesoscale eddies.

Two of the important effects of mesoscale eddies are: (i) the flattening of the slope of large-scale isopycnal surfaces by the eddy-induced overturning circulation, the basis for the Gent–McWilliams parametrization; and (ii) the vertical.

Baroclinic instability is a fluid dynamical instability of fundamental importance in the atmosphere and in the the atmosphere it is the dominant mechanism shaping the cyclones and anticyclones that dominate weather in mid-latitudes.

In the ocean it generates a field of mesoscale ( km or smaller) eddies that play various roles in oceanic dynamics and the transport of. The generation and propagation of baroclinic tides associated with the Monterey Submarine Canyon are qualitatively reproduced by the model with weaker strength.

The surface tidal current simulation is improved, especially in terms of magnitude, when the model has a more realistic stratification through changes in both barotropic and baroclinic.The ocean is a turbulent fluid with processes acting on a variety of spatio-temporal scales.

The estimates of energy fluxes between length scales allows us to understand how the mean flow is maintained as well as how mesoscale eddies are formed and dissipated.

Here, we quantify the kinetic energy budget in a suite of realistic global ocean models, with varying horizontal.

For the baroclinic ocean turbulence models, the inexpensive ROMQG algorithm with modes, less than % of the total, captures the nonlinear response of the energy, the heat flux, and even the one-dimensional energy and heat flux spectra.
