Concept Explanation
 

Climatic Control

Climatic Controls: Permanent factors which govern the general nature of the climate of any location on the earth are called factors of Climatic Controls. The factors of climatic controls are

  • Latitude: The angular distance of a location from the equator in North-South direction is called latitude. Due to curvature of the earth, latitude changes the amount of solar energy received. As a result, air temperature decreases from the equator towards the poles.
  • Altitude: It refers to the height above mean sea level. With increase of height from the earth surface, the temperature decrease and air becomes less dense. Therefore, hilly regions are cooler in summer.
  • Pressure and Wind System: It depends on the latitude and altitude of a place. Thus, it influences the temperature and rainfall pattern of the area.
  • Continentality or Distance from the Sea: The sea exerts a moderating influence on the climate. As the distance from the sea increases, the weather conditions become more extreme (high temperature and rainfall variation between seasons).
  • Ocean Currents: Along with onshore winds, the ocean currents (warm or cold) affect the climate of coastal areas. For example, cold onshore currents bring coolness in coastal areas.
  •  Relief Features: High mountain stop cold or hot winds from reaching a location. It can also cause rain or snow if the place is on the windward side of the mountains. The leeward side of mountains are relatively dry.
