At this website, tropical depressions are identified by an alphabet for
users' convenience. This alphabet is not assigned in chronological order.
When tropical depressions have developed to tropical storms, typhoon
numbers are assigned instead.
Units:
1 kt (knot) = 1.852 km/h = 0.5144 m/s
1 nm (nautical mile) = 1.852 km
