By looking at the quiver plot, you can quickly see how the wind flows across the region and identify areas with stronger or weaker winds −. You may also turn on some directional hint lines if you have trouble estimating angles. Results may be generated for a single site or an entire region. Due to the fact that that wind is a vector quantity and the calculation of wind speed is finding the magnitude of this vector. Wind direction can be rounded to the nearest 10 degrees and wind speed is to the nearest 5 knots. Photo by Paola Galimberti on Unsplash. sqrt(u**2 + v**2) #-- Compute the averages wind_diravg = np.
