Increases in moist‐convective updraught velocities with warming in radiative‐convective equilibrium [PDF]

Quarterly Journal of the Royal Meteorological Society, 2015
The scaling of updraught velocities over a wide range of surface temperatures is investigated in simulations of radiative‐convective equilibrium with a cloud‐system resolving model. The updraught velocities increase with warming, with the largest fractional increases occurring in the upper troposphere and for the highest percentile updraughts.

Climate and climate change in a radiative‐convective equilibrium version of ECHAM6 [PDF]

Journal of Advances in Modeling Earth Systems, 2013
Key Points ECHAM6 is configured to run in RCE with a mixed‐layer ocean RCE similar to tropics in mean vertical structure and overturning circulation Lower climate sensitivity in RCE than in full GCM although feedbacks are present

Radiative–Convective Feedbacks in Idealized States of Radiative–Convective Equilibrium

Journal of the Atmospheric Sciences, 2008
AbstractThis paper examines feedbacks between the radiative heating of clouds and convection in the context of numerical radiative–convective equilibrium experiments conducted using both 2D and 3D versions of a cloud-resolving model. The experiments are conducted on a large domain, and equilibria develop as juxtaposed regions of dry and moist air that ...

Radiative feedbacks in a 1D radiative-convective equilibrium model

2020
<p><span>Equilibrium climate sensitivity (ECS), the change in surface temperature in response to a doubling of atmospheric CO2, is arguably one of the most important quantities when discussing climate change. Despite major improvements in climate modelling over the last decades, ECS estimates lie within a rather ...

Radiative-Convective Equilibrium with Explicit Two-Dimensional Moist Convection

Journal of the Atmospheric Sciences, 1993
Abstract Radiative-convective statistical equilibria are obtained using a two-dimensional model in which radiative transfer is interactive with the predicted moisture and cloud fields. The domain is periodic in x, with a width of 640 km, and extends from the ground to 26 km. The lower boundary is a fixed-temperature water-saturated surface.

Cloudiness and the Radiative, Convective Equilibrium

1970
The dependence of the temperature of the earth’s surface upon the cloud cover at various altitudes is estimated. The effect of contrail on the surface temperature is discussed.

The Role of Relative Humidity in Radiative–Convective Equilibrium

Journal of the Atmospheric Sciences, 2005
AbstractThe 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 optically thick, and 2) the temperature must become only a function of optical depth at each frequency, independent of ...

Radiative-convective equilibrium models of Jupiter and Saturn

Icarus, 1984
Radiative-convective equilibrium models for Jupiter and Saturn have been produced in a study concentrating on the stratospheric energy balance and the possible role of aerosol heating. These models are compared directly with the thermal structure profiles obtained from Voyager radio occultation measurements.

Is Radiative Convective Equilibrium Applicable Over the Tibetan Plateau?

Journal of Geophysical Research: Atmospheres
Abstract Radiative convective equilibrium (RCE) critically constrains tropical climates, but its applicability to elevated terrains such as the Tibetan Plateau (TP) remains unknown. Based on 23 years (2001–2023) of multiple observational data sets, our study provides the first comprehensive observational ...

An Efficient Numerical Approach to Radiative–Convective Equilibrium

Journal of the Atmospheric Sciences, 1977
Abstract An efficient method for computing the radiative–convective equilibrium temperature profile of a vertical–column atmospheric model is described. The equations which specify the equilibrium conditions are linearized to form a matrix equation in which the net radiative heating at levels within regions of radiative equilibrium and the net ...
