The following figure shows the 500hPa isohypses (height contours, solid lines), and one pressure contour for a surface low (dashed line and “L”). a) Indicate on the figure: trough and ridge, super-geostrophic and sub-geostrophic wind, convergence and divergence regions. b) Is the surface low likely to develop further? Defend your answer.
