What are the isotherms? State their Characteristics?

Answer»

The line drawn on maps joining places having the same air temperature are called Isotherms. They are drawn after reducing the temperature to mean sea level to eliminate the variation caused by altitude. The horizontal distribution of temperature is shown with the help of isotherms.

  • Isotherms run east-west and are parallel to the latitudes. 
  • Isotherms take sudden deviation near coasts indicating contrasting temperature conditions between land and water bodies. 
  • Spacing of isotherms indicates latitudinal thermal gradient or steepness of temperature change or intensity of temperature variation. 
  • There is a seasonal difference in spacing of isotherms. Generally they are closer in the month of January while they are widely apart in the month of July. 
  • The isothermal lines have east-west trend following the latitudes. 
  • The ocean currents also influence and deviate the trend of isotherms.
