Based on the following information, derive the magnitude and direction of pressure gradient force, Coriolis force, and friction force per unit mass near the surface; b) draw schematic chart of geostrophic wind, actual wind, ageostrophic wind, pressure gradient force, Coriolis force, and friction force near the surface in the geographical coordinate (note that all these quantities are vectors and you can use relative magnitudes); and c) the frictional veering of the wind across the boundary layer. At 50N, the surface geostrophic wind speed is 35 m s at 160 deg (wind directions use meteorological convention); PBL = 800 m, assume the winds are geostrophic at this height, and assume that the measurement at 1 m height is representative of the surface wind. The observations are 1 20 125 Height (m) Wind speed (m s) Wind direction (deg) 1000 30 155 Based on the following information, derive the magnitude and direction of pressure gradient force, Coriolis force, and friction force per unit mass near the surface; b) draw schematic chart of geostrophic wind, actual wind, ageostrophic wind, pressure gradient force, Coriolis force, and friction force near the surface in the geographical coordinate (note that all these quantities are vectors and you can use relative magnitudes); and c) the frictional veering of the wind across the boundary layer.
