getRoseIndex

public int getRoseIndex(double angle)

The north slice is the last array index not the first one Ex for slice width of 20°: - The first column 20° contain winds between 10 to 30 ° - The last column 360° contains winds between 350° to 360° and 0 to 10° get the rose index to search the mean occurrence p of favourable conditions in the direction of the angle:

Returns:

rose index

getRoseIndex
