Given the following measurements of mean winds and temperature from a 200-m mast in Netherlands on a September night: Table 1. Measurements of mean winds and temperature from a 200-m mast in Netherlands on a September night. Question: Determine the Richardson number (Ri) at heights of 7.5, 15, 30, 60, 100, 140, and 180 m (note: ∂Θ/∂z at height 7.5 m is the potential temperature gradient between 5 m and 10 m).
