Do Self-Aggregation Simulations Depend Crucially on Radiative-Convective Equilibrium (RCE) Initial Conditions?

I've been reading papers on convective self-aggregation, such as Bretherton (2005) and Khairoutdinov (2003), and it's not clear to me why (or whether) self-aggregation depends on the model being ...

Can Horizontal Radiation Fluxes Contribute to Net Column Heating?

I've noticed that in many papers it's common to assume the (daily or longer averaged) vertically integrated radiative heating can be expressed $F_z(\text{TOA})-F_z(\text{SURF})$, where $F_z$ is the ...

What is the radiative forcing change associated with the Chinese 2020 COVID lockdown, and how does this affect the circulation?

The lockdown imposed in China and other countries in response to the COVID 19 pandemic has resulted in a dramatic change in air quality. Factories and transport systems have shut or continue at ...

How to convert solar radiation into equivalent evaporation

I have come across two (apparently) different equations for this purpose. One is mentioned in BASINS software code here $$Rad\_len [inday^{-1}] = \frac{SolRad[langleysday^{-1}]}{((597.3 - 0.57 * ...

Effective Temperature of a Planet and Surface Temperature due to Greenhouse Effect

The effective temperature of the Earth is roughly 12 °F (- 11 °C), which means that in thermal equilibrium when it is emitting as much radiation as it is absorbing, the distribution of wavelengths and ...

About the actual radiative impact of greenhouse gas emission over time

Say we will emit a certain amount of greenhouse gas over the next 50 years (e.g. 100 billion tons CO2-eq in total). What would happen if I implement a certain GHG mitigation effort to cut the same ...

In terms of the greenhouse effect, what is the Earth's heat capacity?

(Question moved from physics to earth science) Has the earth’s atmosphere reached an equilibrium at which the input radiation energy roughly equals its output, or is the output significantly lower ...

Why are solar longwave and terrestrial shortwave radiations neglected in radiation balance models?

For an assignment I was given the question: Explain why solar radiation is neglected in atmospheric “long wave” calculations and Earth radiation is neglected in atmospheric “short wave” calculations. ...
