pV=nRT
Pressure is proportional to temperature. When pressure drops, temperature drops. Alternatively, lower pressure means that the molecules collide lesser and have lower energies. Temperature drops as a result.

Gas expands and while doing so, absorbs heat energy from environment. this causes cooler outside objects. Hence chilling and condensation.

At the surface, in the tropics, the difference between high and low is a few millibars. At the poles it's nearly zero.

condensation takes when a gas of two different temp. meets and equalize ( dew point)

PV = nRT. If that isn't enough, go look up the 'Ideal Gas Law'.
