Figure 3.

Horizontal and oblique banded patterns obtained by numerical simulations of Eq. (1). (a) Oblique banded pattern to the left clockwise (oblique left vegetation pattern), (b) horizontal, and (c) oblique banded pattern to the right counterclockwise (oblique right), respectively. All numerical patterns are obtained using a noisy initial condition. All patterns are obtained for the same parameters $\mu =0.98$, ${\chi }_f=2.1$, ${\chi }_c=1.2$, $D=0.2$, $x_{0c}=-0.2,x_{0f}=0.5,y_{0i}=0$, $l_{\mathit{fx}}=l_{\mathit{fy}}=0.9$, $l_{\mathit{cx}}=5$, and $l_{\mathit{cy}}=3.5$.
