How much increase in the atmospheric pressure when the global temperature is elevated by 12 C?

The deep-sea temperature was $12º$C higher $50$ My ago. I would like to know how much the atmospheric pressure at sea level had decreased and how much the water-vapour changed. One can consider no ...

How to plot orography for vertical profile of a certain variable along pressure levels in GRADS

I am using GRADS (1, 2, 3) to plot ERA reanalysis relative humidity profile for latitudinal average of 15N to 37N, and along the longitude from 40E to 130E. The orography is quite obvious and thus ...

Internal energy, enthalpy, and work in the atmosphere

I'm writing a toy radiative-convective atmospheric model and need to relate the heat flux convergences (either surface sensible heat flux or the radiative flux) to changes in atmospheric layer ...

Phase conversion of snow and ice due to irradiation versus melting

A few years ago another question touched on the relative rates of sublimation versus melting in terms of snow and snow pack disappearance. What was unusual about the answer is the huge range of ...

Doesn't the sublimation rate on glaciers depend on the (specific) latent heat of sublimation of water ice?

On p. 6 of this article: Bliss, A.K., Cuffey, K.M., Kavanaugh, J.L., 2011. Sublimation and surface energy budget of Taylor Glacier, Antarctica. Journal of Glaciology 57, 684–696. There is an ...

Is there such a thing as virtual barotropic?

In meteorological terminology within dynamics, there are usually one of two unique assumptions made: Baroclinic- density is a function of both temperature and pressure : $\rho(x,y,z,t)=\frac{P(x,y,z,...

Is this a valid semi-diagnostic equation for Omega?

Beginning with the Primitive equations governing atmospheric motion for a dry gas, primarily the ideal gas law, and the conservation of mass and energy, neglecting diffusivity. $$P=\rho R T$$ $$\...
