“…The seasonal variable is defined based on the four seasons, the directions variables are defined based on eight directions (N, NE, E …), and the locational variables are clustered into two groups (black, i.e., upper left, and gray, i.e., lower right), as shown in Figure 7. A similar binary discretization of the location variables is learned in Glavind and Faber (2020) using the entire hindcast data set (23 platforms).…”
