Which quantity does the spacing of thickness contours give?

  • A.The thermal wind
  • B.The geostrophic wind at the mid-point of the layer whose thickness the chart has been drawn for
  • C.The vertical velocity
  • D.The rate at which the mean temperature of the layer is changing with the passage of time at a point

Answer: A

Because thickness is proportional to layer mean temperature, and the thermal wind is proportional to the horizontal temperature gradient, the spacing of thickness contours gives the thermal wind directly. The thermal wind blows along the thickness contours with low thickness, and therefore cold air, on the left in the northern hemisphere. This makes a thickness chart a direct display of the vertical shear, which is why it is such a useful analytical tool.
