General shapes of the clouds within the simulations. Panel a: relation between the ratio of the middle half-axis over the largest b/c and the ratio of the smallest half-axis over the largest a/c assuming clouds have a ellipsoidal shape. The characterisation of the shape the one used in van der Wel et al. (2014). The contour lines and symbols are the same as in Fig. 6a. Panel b: marginal distributions of the ratio of the ellipsoidal half-axes of the clouds between the simulations.
