A parametric model of vertical eddy fluxes in the atmosphere

TLDR
In this paper, a model for the representation of vertical eddy fluxes of heat, momentum and water vapour in a forecast model is presented, and two tests are presented, using the scheme in a one-dimensional model: the simulation of the diurnal cycle and the transformation of a polar air mass moving over the warm sea.
Abstract
A scheme for the representation of the vertical eddy fluxes of heat, momentum and water vapour in a forecast model is presented. An important feature of the scheme is the dependence of the diffusion coefficients on the static stability of the atmosphere. Two tests are presented, using the scheme in a one-dimensional model: the simulation of the diurnal cycle, and the transformation of a polar air mass moving over the warm sea.

A New Vertical Diffusion Package with an Explicit Treatment of Entrainment Processes

TL;DR: In this article, a revised vertical diffusion algorithm with a nonlocal turbulent mixing coefficient in the planetary boundary layer (PBL) is proposed for weather forecasting and climate prediction models, which improves several features compared with the Hong and Pan implementation.

Oceanic vertical mixing: A review and a model with a nonlocal boundary layer parameterization

TL;DR: In this article, a new parameterization of oceanic boundary layer mixing is developed to accommodate some of this physics, including a scheme for determining the boundary layer depth h, where the turbulent contribution to the vertical shear of a bulk Richardson number is parameterized.

Flux-Profile Relationships in the Atmospheric Surface Layer

TL;DR: In this article, the free constants in several interpolation formulas can be adjusted to give excellent fits to the wind and temperature gradient data, and the behavior of the gradients under neutral conditions is unusual, however, and indicates that von Karman's constant is ∼0.35, rather than 0.40 as usually assumed, and that the ratio of eddy diffusivities for heat and momentum at neutrality is ∼1.0.

Efficient prediction of ground surface temperature and moisture, with inclusion of a layer of vegetation

TL;DR: In this paper, an efficient one-layer foliage parameterization was developed that extends continuously from the case of no shielding of the ground by vegetation to complete shielding, including influences of both ground and foliage albedos and emissivities, net leaf area index, stomatal resistance, retained water on the foliage, and several other considerations.

A review of flux-profile relationships

TL;DR: In this paper, Businger et al. reviewed the preferred relationships of Dyer and Hicks (1970) in the constant flux layer, and found that the preferred relationship was the one of the Dyer-H Hicks pair.

On Formation and Intensification of Tropical Cyclones Through Latent Heat Release by Cumulus Convection

TL;DR: In this paper, the effect of latent heat release by deep cumulus convection in a conditionally unstable atmosphere is investigated and a method devised to include this effect directly in the equations for large scale flow is then applied to the hurricane formation problem by incorporating it into timedependent, circular symmetric dynamic hurricane models, either in gradient-wind balance or unbalanced.
