Weather instruments are used to take measurements of
temperature, wind, humidity, and rainfall, as well as other
atmospheric factors which describe the local weather and climate.
Different types of instruments are used to measure different
parameters and there are many types to choose from. The variables
measured with these types of instruments are wind speed and
direction, pressure, humidity, temperature, and precipitation,
including rain and snow.
Barometer
A barometer is an instrument that is used in measuring the
amount of atmospheric pressure. It is mostly used in weather
forecasting. A barometer can also be something that reflects change
in opinions or circumstances.
Wind Gauge.
A wind gauge, also known as an anemometer, is a tool used to
measure wind speed, direction and pressure. The first mechanical
wind gauge was created in 1450 by Leon Battista Alberti, an Italian
artist and architect. Modern anemometers are most commonly used in
weather stations.
Rain Gauge. A rain gauge is an instrument used by meteorologists
and hydrologists to measure precipitation (e.g. rain) in a certain
amount of time. It usually measures in millimeters. Rain gauge is
an meteorological instrument for determine the depth of
precipitation (usually in mm) that occurs over a unit area (usually
one meter squared) and thus measuring rainfall amount. One
millimeter of measured precipitation is the equivalent of one liter
of rainfall per meter squared.
Wind VaneA wind vane is a weather instrument used to determine
the direction the wind is blowing. The wind vane spins round and
round freely on a vertical rod and points on the direction the wind
is blowing from.
A THERMOMETER
A thermometer 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. A scale then shows what the actual
temperature is.
