Direction: |
One of eight compass directions. |
Percentage Occurrence: |
The percentage of 1 year during which storms occur from this direction. |
Notes
(a)“North” is defined as being the direction of the positive sense of the global Y axis. ”West” is then in the direction of the positive sense of the global Z axis, ”South” in the negative sense of global Y, and ”East” in the negative sense of global Z. The other directions are naturally intermediate to these.
(b)Waves in the ”North” direction are defined as travelling in the positive global Y direction, that is towards rather than from the compass point, and likewise for the other directions.
(c)The total of all of the percentage occurrence values must equal 100%.
