Does Earth's air leak into space over time?

From my current understanding, Earth's atmosphere and air are held by the balance of two forces: 1. Earth's gravity and 2. Air pressure from air out to space. Is my understanding correct? So, do ...

Are clouds significantly easier to simulate in weather models than climate models?

Cloud forcing is still one of the major uncertainties of radiative forcing in climate modeling because there are so many uncertainties in it (and parametrizations). But also because the timescale of ...

How does the lapse rate in clouds compare with the lapse rate of air?

So moisture decreases the temperature lapse rate (relative to the dry adiabat). My question is this: does a cloud decrease the lapse rate at the same rate as 100% humidity would decrease it? Or would ...

Why are most cirrus clouds present over the equator and over tropical continents?

As quoted from the AR5 IPCC report (chapter 7) here. Most high cloud (mainly cirrus and deep cumulus outflows) occurs near the equator and over tropical continents, but can also be seen in ...

Are there any quantities defined analogically to the virtual temperature, but for other gases?

The virtual temperature is a pseudo-temperature taking into account water vapour in the atmosphere in such a way, that the resulting quantity can be used with the ideal gas law and the molar mass for ...

Is global warming occuring only because of humans? [duplicate]

I learned that human activities produce gases that deplete the ozone layer, and create the greenhouse layer, which increases the world's temperature. (And seems real , now in Thailand it's 35 degree ...

Bifurcation Scenarios in the Atmosphere

I read that the mathematical definition of bifurcation is that, at a critical value of a parameter that governs the dynamical system, the system changes to a topologically different system than the ...

Why does the meandering pattern of the jet stream itself propagate?

It is well known that the jet stream follows an overall meandering pattern, but what is less well known is that this meandering pattern itself moves as a wave with a velocity much slower than the ...

Is climate chaotic?

The atmosphere is a highly dynamical system, and exhibits many chaotical features. An operational weather forecasting model tries to model an initial value problem, in fact one of the most famous ...

How will cloud feedback effects on the climate change as the result of global warming?

So global warming will increase the tropospheric temperatures, which, in turn, would make the clouds higher than they otherwise would be. And higher clouds (especially cirrus clouds) tend to trap in ...

How can I estimate a 2 m temperature from / in an atmospheric model?

Numerical models of the atmosphere usually have their first atmospheric grid level well above 2 m, but the temperature at 2 m above ground level is something one often wants to calculate with such a ...
