How are tropical storms named?
Tropical storms are named by the World Meteorological Organization (WMO) picked from a list that rotates every year for 6 years if they display a rotating circulation pattern & wind speeds reaching 39 miles per/hr & when the tropical storm’s wind speeds go above 74 mph its develops into a hurricane.
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than 33 knots (61 km/h; 38 mph), names are generally.
What determines the name of a tropical storm?
Tropical storms require a combination of factors to develop: ocean water warmer than 80°F (26.5°C),an atmospheric disturbance, usually an area of low pressure and cool air, andlow vertical wind shear, meaning that wind speeds must be consistent at different altitudes.
The next thing we asked ourselves was: when did they start naming tropical storms?
Hurricanes are such a normal part of the tropics season that it can be easy to forget that the modern convention of naming hurricanes started not long ago. The National Hurricane Center began using a naming system to designate storms with maximum sustained winds of 39 mph or more in the Atlantic Ocean in 1979.
