Factors that Affecting Controlling Temperature Control

The basic factors that affect Temperature Distribution are highlighted below:

[su_box title=”Factors Affecting Temperature Distribution” box_color=”#7960a0″]

  • The temperature of air at every place is influenced by :
    • The latitude of the place
    • The altitude of the place
    • Distance from the sea
    • The air- mass circulation
    • The presence of warm and cold ocean currents
    • Local aspects[/su_box]

[su_box title=”The latitude” box_color=”#7960a0″]

  • The temperature of a place is determined by the insolation received.
  • The insolation differs according to the latitude, therefore, the temperature also differs consequently.[/su_box]

[su_box title=”The altitude” box_color=”#7960a0″]

  • The atmosphere is indirectly heated by terrestrial radiation.
  • Therefore, the places adjacent to the sea-level record higher temperatures than the places located at higher elevations.
  • The temperature usually decreases with increasing height.
  • The rate of decrease of temperature with height is called the normal lapse rate.[/su_box]

[su_box title=”Distance from the sea” box_color=”#7960a0″]

  • The main factor that influences the temperature is the position of a place with respect to the sea.
  • The sea gets heated slowly and loses heat slowly compared to land.
  • Land heats up and cools down rapidly.
  • So, the difference in temperature over the sea is less compared to the terrestrial surface.
  • The places located near the sea come under the moderating influence of the sea and land breezes which regulate the temperature.[/su_box]

[su_box title=”Air-mass and Ocean currents” box_color=”#7960a0″]

  • The passage of air masses also affects the temperature like the land and sea breezes.
  • The places which come under the effect of warm air-masses experience higher temperature and the places that come under the influence of cold air- masses experience lower temperature.
  • Likewise, the places situated on the coast where the warm ocean currents flow record higher temperature than the places situated on the coast where the cold currents flow.[/su_box]
