Problem 2.

p = 750 hpa, t = 25°c. let the mixing ratio at this point be 0.015 and the saturation mixing ratio be 0.025. for a parcel of air with these properties, find the:

a) saturation mixing ratio

b) potential temperature

c) dewpoint temperature

d) wet-bulb temperature

e) relative humidity

f) vapour pressure

g) values of p and t at the condensation level. the condensation level is the level at which the parcel becomes saturated if it is lifted adiabatically.

h) amount of water vapour (in g kg-1) that is condensed as the parcel ascends from the condensation level to 500 hpa.

i) assume that half of the water condensed on its ascent to 500 hpa is precipitated out of the parcel. estimate its temperature when it descends back to 750 hpa.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
