Thus strong winds and closely drawn isobars are correlated. Aloft, winds blow clockwise around a high and counterclockwise around a low, parallel to isobars. Near the surface, more friction causes the winds to cut across the isobars-outward in high pressure cells and inward in low pressure cells. The opposite deflection directions from the northern hemisphere prevail. Pressure Gradient Force, Coriolis Force, Centripetal Force, and Friction.
Friction reduces the Coriolis force because it slows down the wind.
Consequently, as Cf decreases it has less effect opposing the Pgf, thus the wind has more of a tendency to cut across the isobars at a larger angle. Put your back to the wind aloft and the low will be to your left. The low will be to your left. Explain the effect that friction has on wind speed and direction. More friction will cause the air to flow across the isobars at a greater angle.
