Figure 3: (a) A typical neutral curve , defined using expression (11) for different values of . (b) Numerical calculation of the stability on space. (c) An illustration of the dispersion relation ( versus the wave number ), where  (m2·day−1) and the other parameters are given in Table 1. Blue line:  (m·day−1); red line:  (m·day−1); green line:  (m·day−1).
