Dear Dr.Dharam, Kindest regards, I give the meaning of Amplitude:In any oscillatory motion of a quantity amplitude means the amount of displacement.This meaning is applied to the motion of an air particle displaced by a sound wave.In case of a pendulam the amplitude is half the length of the swing.Perhaps, temperature amplitude means the average of diurnal variation ( mean of maximum temperature of the day Plus minimum temperature of the day). I further verify and come back to you.
