Question

Which climate zone experiences the greatest change in temperature during the year?

Answer 1

Deserts...They can be 100+ in the summer and below freezing in the winter...some even have 60 degree swings between night and day

Answer 2

I agree with Steve.  The lack of water vapor has a big influence on the swing.  Areas in the middle latitudes in the middle of the Continent have huge swings too, for the same reason.  The poles may be even greater - especially for seasons - though usually below freezing. But a 40 degree swing from day to night is not unusual in the desert or mid continent.
