Planetary science: Smog report
Robert E. Samuelson
Abstract
The hazy atmosphere surrounding Titan, Saturn's largest satellite, changes with the seasons. New theoretical work suggests how the motion of smog particles can account for the curious features of the haze.
During the course of a year, planetary atmospheres are, as a rule, heated by the Sun more at the equator than at the poles. This creates a temperature difference between equator and pole, and an atmosphere will attempt to reduce this difference by transporting heat dynamically between them.
