Effect of friction on flow around lows and highs

  • Q: How does friction affect flow around lows and highs near the surface?????

  • Q: Due to the frictional turning of the wind such that it crosses the isobars, what can you infer about the vertical motions in the vicinity of a



1.  Why is it impossible for a hurricane to cross the equator?

2.  With the aid of a diagram, explain why winds flow counterclockwise around low pressure and clockwise around high pressure in the northern hemisphere.  Indicate all relevant forces on your diagram.  How does the flow direction around highs and lows change when in the southern hemisphere?
