A cyclone is any mass of air that spirals around a low pressure center. It is an organized collection of thunderstorms embedded in a swirling mass of air. In general, both typhoons and hurricanes are tropical cyclones but differ in their locations. The difference between hurricane and typhoon is that tropical cyclones in the west Pacific are called Typhoons and those in the Atlantic and east Pacific Ocean are called Hurricanes. It's the longitude that matters.
The storm surge, or the increase in sea level due to the cyclone, is typically the worst effect from landfalling tropical cyclones, historically resulting in 90% of tropical cyclone deaths. The broad rotation of a landfalling tropical cyclone, and vertical wind shear at its periphery, spawns tornadoes. hurricane or typhoon (sometimes simply referred to as a tropical cyclone, as opposed to a depression or storm) is a system with sustained winds of at least 34 metres per second (66 kn) or 74 miles per hour (119 km/h).
