Thermal circulations

  • many mesoscale phenomena are the result of a thermal circulation:

  • thermal circulation - a circulation generated by pressure gradients produced by differential heating

  • thermal circulations tend to be shallow - do not extend up through the depth of the troposphere

    examples of thermal circulations:

    • sea breeze
    • land breeze
    • monsoons
    • mountain and valley breezes
  • Q: So how is a thermal circulation generated? Let's consider the formation of the sea/land breeze circulation as an example......
