Figure 15. Diurnal cycle of the 950–800-hPa-mean streamwise (\(s\)) and crosswise (\(n\)) horizontal (green), geostrophic (blue), and ageostrophic (red) winds (m s-1) during November 2013–March 2014 at (a) C1, (b) C2, (c) C3, and (d) C4 regions. Streamwise components in solid lines and crosswise components dashed. Geostrophic and ageostrophic crosswise components balance around zero m s-1 owing to the rotated coordinate system.
