Why
are tropical cyclones (Tropical Depressions, Storms, Hurricanes and Typhoons)
named? (Credit: NOAA/NHC)
Tropical cyclones are named to provide ease of communication between forecasters
and the general public regarding forecasts, watches, and warnings. Since
the storms can often last a week or longer and that more than one can
be occurring in the same basin at the same time, names can reduce the
confusion about what storm is being described. According to Dunn and Miller
(1960), the first use of a proper name for a tropical cyclone was by an
Australian forecaster early in the 20th century. He gave tropical cyclone
names "after political figures whom he disliked. By properly naming
a hurricane, the weatherman could publicly describe a politician (who
perhaps was not too generous with weather-bureau appropriations) as 'causing
great distress' or 'wandering aimlessly about the Pacific.'" (Perhaps
this should be brought back into use
During
World War II, tropical cyclones were informally given women's names by
US Army Air Corps and Navy meteorologists (after their girlfriends or
wives) who were monitoring and forecasting tropical cyclones over the
Pacific. From 1950 to 1952, tropical cyclones of the North Atlantic Ocean
were identified by the phonetic alphabet (Able-Baker-Charlie-etc.), but
in 1953 the U.S. Weather Bureau switched to women's names. In 1979, the
World Meteorological Organization (WMO) and the U.S. National Weather
Service (NWS) switched to a list of names that also included men's names.
The
Northeast Pacific basin tropical cyclones were named using women's names
starting in 1959 for storms near Hawaii and in 1960 for the remainder
of the Northeast Pacific basin. In 1978, both men's and women's names
were utilized.
The
Northwest Pacific basin tropical cyclones were given women's names officially
starting in 1945 and men's names were also included beginning in 1979.
Beginning on 1 January 2000, tropical cyclones in the Northwest Pacific
basin are being named from a new and very different list of names. The
new names are Asian names and were contributed by all the nations and
territories that are members of the WMO's Typhoon Committee. These newly
selected names have two major differences from the rest of the world's
tropical cyclone name rosters. One, the names by and large are not personal
names. There are a few men's and women's names, but the majority are names
of flowers, animals, birds, trees, or even foods, etc, while some are
descriptive adjectives. Secondly, the names will not be allotted in alphabetical
order, but are arranged by contributing nation with the countries being
alphabetized.
The
North Indian Ocean region tropical cyclones are not named.
The
Southwest Indian Ocean tropical cyclones were first named during the 1960/1961
season.
The
Australian and South Pacific region (east of 90E, south of the equator)
started giving women's names to the storms in 1964 and both men's and
women's names in 1974/1975.
This
week's question comes from Rob Gutro. Rob is a meteorologist who works
at NASA Goddard in Public Affairs. He did forecasting for the Weather
Channel Radio Network, was a technical writer for NOAA, provided broadcasts
on NOAA Weather Radio in Baltimore, and was a radio personality for 20
years in various cities.
