Like any tropical cyclone, there are few main requirements for typhoon formation and development: (1) sufficiently warm sea surface temperatures, (2) atmospheric instability, (3) high humidity in the lower to middle levels of the troposphere, (4) enough Coriolis effect to develop a low pressure center, (5) a pre- …
How do you find the speed of a typhoon?
One knot means a speed of moving one nautical mile (nm) in one hour. Knot is used for representing the maximum wind speed at the center of a typhoon, or a movement speed of a typhoon on this website. Because 1nm = 1.852km, 1kt = 1.852km/h = 0.5144m/s.
