Effect of friction on flow around lows and highs - associated weather

  • at the center of a surface low, the air converges, and then must rise

  • at the center of a surface high, the air is diverging, and must be coming from aloft due to sinking motion

  • Hence, one can expect cloudy, raining, fowl weather near a surface low

  • one should expect, clear, dry, pleasant weather near a surface high
