Hydrometeorological Hazards Flashcards
Is a rotating, organized system of clouds and thunderstorms that originate over the tropical waters.
Tropical Cyclone
Tropical cyclones rotate in a (?) direction
in the northern hemisphere (conversely, (?) in the southern hemisphere).
Counterclockwise, Clockwise
(Classification of tropical cyclones according to the strength of the associated winds.)
a tropical cyclone with maximum sustained winds of
up to 61 kph.
Tropical depression (TD)
(Classification of tropical cyclones according to the strength of the associated winds.)
a tropical cyclone with maximum wind speed of 62 to 88
kph.
Tropical storm (TS)
(Classification of tropical cyclones according to the strength of the associated winds). a tropical cyclone with maximum wind speed of
89 to 117 kph.
Severe tropical storm (STS)
(Classification of tropical cyclones according to the strength of the associated winds.)
a tropical cyclone with maximum wind speed of 118 to 220 kph.
Typhoon (TY)
(Classification of tropical cyclones according to the strength of the associated winds.)
a tropical cyclone with maximum wind speed exceeding
220 kph.
Super typhoon (STY)
are generally local storms produced by cumulonimbus clouds and are
always accompanied by lightning and thunder, usually with strong wind gusts, heavy rain
and sometimes with hail and/or tornado.
Thunderstorms
is the overflowing of stream or bodies of water or the accumulation of water over
areas that are not normally submerged.
Flood
are also caused by heavy precipitation in a short period of time
characterized by a rapid current which usually lasts for 6 hours.
Flash Floods
is the rise and onshore surge of seawater as the result primarily of the winds
of a tropical cyclone, and secondarily of the surface pressure drop near the center of the
tropical cyclone.
Storm surge
is a significant increase in ocean temperature over the eastern and central Pacific
Ocean. It occurs at irregular intervals ranging from 2-7 years usually developing in the
early months of the year and decay the following year.
El Niño
is described as cooler-than-normal sea surface temperatures in the central and
eastern Pacific Ocean, near the equator off the west coast of South America.
