refers to the rapid
rotating storm formed over tropical
oceans. It has a low-pressure center
with strong winds and thunderstorms
that may bring heavy rains. Tropical
cyclone is a general term and can be
categorized depending on its
maximum wind speed.
Cyclone
is a type of tropical cyclone that
forms over tropical or subtropical
waters. It has winds of 74 mph or
more. The term hurricane is used if it
originates in the North Atlantic,
Central North Pacific, and eastern
North Pacific
Hurricane
is a mature tropical cyclone that
usually originates in the northwest
Pacific. Typhoons usually have wind
speeds of around 118 to 220 kph.
Typhoon
measures the air
temperature.
most thermometers are closed
glass tubes containing liquids
such as alcohol or mercury. When
air around the tube heats the
liquid, the liquid expands and
moves up the tube.
Thermometer
a
scientific instrument used to
measure atmospheric pressure, also
called barometric pressure.
The atmosphere is the layers
of air wrapped around the Earth. That
air has a weight and presses against
everything it touches as gravity pulls
it to Earth. Barometers measure this
pressure.
Barometer
composed of two
similar thermometers. The bulb of
one thermometer is kept wet (by
means of a thin, wet cloth wick) so
that the cooling that results from
evaporation makes it register a
lower temperature than the drybulb thermometer.
Phsychrometer
an instrument that
measures wind speed and wind
pressure. Anemometers are
important tools for meteorologists,
who study weather patterns.
anemometer
very basic
devices that measure wind
direction and provide a rough idea
of the wind’s intensity. They
comprise a tubular piece of fabric
or thin, flexible fabric attached to a
pole. In windless conditions, the
fabric hangs vertically from the
attached p
Windsock
also known as
a weathervane) is
an instrument that tells you
the wind direction. Specifically,
a wind vane lets you know what
direction the wind is coming from
Wind Vane
is an instrument
used to measure relative
humidity. Humidity is the measure
of the amount of moisture in the
air. A psychrometer is an example
of a hygrometer. A psychrometer
uses two thermometers to
measure relative humidity; one
measures the dry
-bulb
temperature and the other
measures the wet
-bulb
temperature
Hygrometer
measures the amount
of rain that has fallen over a
specific time period.
Rain gauge
also known as
sounding balloon, is a balloon (specifically a type
of high
-altitude balloon) that
carries instruments aloft to send
back information on atmospheric
pressure, temperature, humidity
and wind speed by means of a
small, expendable measuring
device called a radiosonde.
