How does altitude affect the yearly temperature at a location?
The solar radiation is a short-wave radiation which does not heat the atmosphere directly when the solar radiation passes through it.Instead the atmosphere is heated from the bottom by the reflected long-wave radiation from the earth’s surface by conduction.Hence the temperature of the atmosphere decreases with altitude.So, a place situated at an altitude will have lower temperature throughout the year depending upon its height from the earth’s surface thus affecting the average yearly temperature.That is why most of the mountain tops with an approximate height of 5 kms(approximate height of freezing level) and above will have snow covering throught the year.
