This is primarily because the Northern Hemisphere has more landmass, which heats up more readily than ocean, pulling the zone of maximum annual average temperature northwards.
Yes, it shifts seasonally, following the apparent movement of the sun, moving north during the northern summer and south during the southern summer.
It is a standard term in climatology, meteorology, physical geography, and environmental sciences.

Memory Aids
Mnemonic
Imagine Earth wearing a belt of warmth. This 'heat belt' is the Thermal Equator, and it usually sits above the waistline (geographical equator) because the northern 'shoulders' (landmasses) soak up more sun.
