Examples
Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere).
A haze permeates most of Triton's troposphere, thought to be composed largely of hydrocarbons and nitriles created by the action of sunlight on methane.
Actually, that isn't true; if greenhouse gasses are the cause of the observed warming (models also predict this), the surface and lowest part of the troposphere should warm but further up warming is less and eventually switches over to cooling.
As the aerosols grow and coagulate, they settle down into the upper troposphere where they serve as nuclei for cirrus clouds and further modify the Earth's radiation balance.
Due to the warming of the troposphere from the increased greenhouse effect of the polar stratospheric clouds, the stratosphere would cool and would potentially increase the amount of polar stratospheric clouds.
Clouds observed above Triton's limb by Voyager 2. Turbulence at Triton's surface creates a troposphere (a "weather region") rising to an altitude of 8 km.
