■ FACTORS CONTROLLING, THE DISTRIBUTION OF TEMPERATURE
□ Nature of Ground Surface
◇ The nature of ground surface in terms of colour, vegetation, land use practices etc. affects the distribution of temperature. The snow-covered surfaces receive very low amount of insolation because they reflect 70 to 90 per cent of incoming shortwave solar radiation and thus polar and arctic areas are characterized by extremely low temperature throughout the year.
◇ On the other hand, sandy surfaces record high temperature during day time in the tropical and subtropical areas because they absorb most of solar radiation very quickly as they reflect only 20 to 30 per cent of solar radiation.
