Formulation of the Moist Adiabatic Lapse Rate Equation
In the relationship r = ϵe/p−e: mixing ratio of the mass of water vapour to the mass of dry air.
Question: What is ϵe
For clarification see question Moist adiabatic lapse rate
I know that the ratio ...

What happens to the "curvature term" in the equations of motion for a rotating fluid near Earth's poles?
For a rotating fluid in spherical geometry, one of the terms of the equations of motion is the "curvature term". For example, for the zonal component of velocity (corresponding to eastward ...

Why does warm, moist air generate a low-pressure area? [closed]
In school, I learned the mechanism of high and low pressure areas, which roughly goes like this:
In the tropics, the sun warms up the air during the day. Water evaporates, so that the air gets warm ...

Is angular momentum conserved on a spinning sphere, specifically Earth [closed]
Specifically in relation to meteorology. I was wondering if the angular momentum an object, lets say a parcel of air has due to the roation about the earths axis. Is it conserved if moved to a ...

Forecasted temperature in the shade vs. theoretical temperature in the sun
I understand that different objects absorb different amounts of light (blackbody absorption). I wonder how feasible it would be to calculate the approximate temperature in the sun based upon the ...

Katabatic Wind: if the ground "radiates" it's heat during the night, why doesn't the air above it warm?
In this picture (from EasyPPL mock exam) and in a few other sources (e.g. https://www.britannica.com/science/katabatic-wind) it is stated that at night, the ground radiates heat and the air passing ...

How can flow along a stream line with constant pressure spatially change its velocity?
I'm going crazy:
In meteorology there is a term "geostrophic wind". It is wind moving along surfaces of constant pressure.
https://en.wikipedia.org/wiki/Geostrophic_wind
How is the step from

Confusion about the horizontal pressure gradient force being equal to the gradient of the geopotential in pressure coordinates
I see many sources in atmospheric dynamics express the following:
$\frac{1}{\rho}(\nabla p) = \nabla_p \phi$
For example this source equation 10.
The reasoning given is that $\frac{1}{\rho}(\frac{\...

Application Of Kirchoff's Law In A Desert [closed]
Homework Statement::
Sand is rough and black so it is a good absorber and radiator of heat depending on temperature.
During the day, sand's radiation of the sun's energy superheats the air and causes ...

Do forests create wind?
Forests evapotranspire more water vapor into air than surrounding areas, have more clouds, and are usually cooler (because of evaporative cooling). How does this affect the air pressure of forests? ...

How come air masses displace air when it moves rather than mixing with it? [duplicate]
It seems if you had one mass or air moving towards another air mass, that the molecules within that first air mass would be able to penetrate into the second air mass because the distance between air ...
