“Why is the North Pole warmer than the South Pole? I changed it each year, to confuse students who looked at last year’s exam; “Why is the South Pole colder than the North Pole?”
Most people have no idea about the geography of the Poles and assume
they are climatically the same. They are literally polar opposites and
that is important in understanding the significance for global climate.
The major driving force for atmospheric circulation is the
temperature difference between the Poles and the Equator – the gradient.
Theoretically, maximum heating at the Equator and minimum at the Poles
creates a single cell circulation system
