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 ...

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 ...

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 ...

What are the impacts of sublimation on an annual mountain snowpack?

Massive amounts of freshwater rests atop the world's mountains in the form of ice, snow, permafrost, and glaciers. Many areas of the world rely upon the melting of snow and ice to recharge their ...

Why does every tsunami travel differently?

Tsunamis are quite interesting, as they only happen after a large displacement of water. Usually, the waves travel quite weirdly. Sometimes there are waves which bounce off of land and go back to sea....

How can I calculate the average latitudinal temperature anomaly between a city and all other locations along the city's latitude?

E.g. How could I calculate the average temperature anomaly between, say, Boulder, CO and all other locations along the 40N parallel? What about Boulder, CO, and all other locations along 40N at ...
