Snow cover and land temperature are connected, but one does not necessarily cause the other. Snow certainly influences how hot or cold the land feels to the touch, and land temperature influences whether or not snow remains on the ground or melts away. But the most obvious global pattern these images demonstrate is not the effect of temperature and snow cover on each other, but the effect of latitude and elevation on each.
