4. PREFACE
• This project will explain you the some of
the Meteorological Instruments, their
working, and even their uses.
• Many unknown facts will be showed in the
in the upcoming Slides.
SO LETS GO THE NEXT SLIDE

5. • Meteorology Definition:
The branch of science concerned with the
processes and phenomena of the atmosphere,
especially as a means of forecasting the weather, is
called Meteorology.
• Meteorological Instruments:
Meteorological instruments are
the equipment used to sample the state of the
atmosphere at a given time. Each science has its own
unique sets of laboratory equipment.

7. • A U-shaped thermometer, designed by J. W. Six, with a bulb
that contains creosote. Mercury occupies the bend in the
tube and a spring-loaded index rests on the mercury's
meniscus in each leg of the tube. These indexes are displaced
by the expansion and contraction of the mercury, remaining
at their extreme positions to give readings of the maximum
and minimum temperatures. They are reset by the use of a
magnet.

9. • A mercury barometer is a tool that uses the element
mercury to measure barometric (atmospheric) pressure to
predict weather.
• It is a device that consists of an upside-down tube filled
with mercury that is in a vessel full of mercury. The
atmosphere (or the air) pushes down on the mercury in the
vessel, which in turn, pushes the mercury in the tube up.
And the height of mercury in this tube (also known as the
height of mercury column) is used as a measure of
atmospheric pressure. For instance, 1 atmospheric pressure
causes a height of 760 mm of mercury in the tube

11. • It is a device for measuring atmospheric
pressure without the use of fluids. It consists
of a partially evacuated metal chamber, the
thin corrugated lid of which is displaced by
variations in the external air pressure.

12. • The only use of the Aneroid barometer is to
measure the Atmospheric pressure.
• There are different types of aneroid barometers,
such as the altimeter, which measures altitude, or
distance above sea level. Another example is a
barograph, which is a modified aneroid barometer
that provides constant readings of atmospheric
pressure on graph paper.

13. • A weather vane, wind vane, or weathercock is an
instrument for showing the direction of the wind.
They are typically used as an architectural ornament
to the highest point of a building.

14. • an instrument for measuring the speed of the
wind, or of any current of gas.

15. • It is used at the airports to calcite accurate wind
data under all conditions.
In order for wind speeds to be comparable
from location to location, the effect of the terrain
needs to be considered, especially in regard to
height. Other considerations are the presence of
trees, and both natural canyons and artificial
canyons (urban buildings). The standard
anemometer height in open rural terrain is 10
meters.

17. • A rain gauge is an instrument used
by meteorologists and hydrologists to
measure precipitation (e.g. rain, snow, hail or
sleet) in a certain amount of time. It usually
measures in millimetres. Rain gauge is a
meteorological instrument for determining the
depth of precipitation (usually in mm) that occurs
over a unit area (usually one metre squared) and
thus measuring rainfall amount. One millimetre
of measured precipitation is the equivalent of
one litre of rainfall per metre squared.

18. Standard Rain Guage

19. • A hygrometer, also known as a
psychrometer, is an instrument used for
measuring the moisture content in the
atmosphere.
Modern Hygrometer

20. • All skycam is a stand-alone Astro and weather
video device enclosed in a weather proof
dome that provides wide view at the entire
sky.
• All day all night rain or shine images from the
all-sky can be viewed on the TV captured on to
a laptop or PC or streamed live over the
Internet. The cameras fisheye lens gives you a
180 degree view from horizon to horizon.

22. • You can use this live video to observe the sunrises
and sunsets, cloud activity, moving storms, starry
night sky, and more.
• In meteorological applications camera is used to
study cloud cover, UV index, timelapse photography
of clouds, cloud fractional coverage, sky polarization,
the computation of cloud base height, as well as
wind speed at cloud heights.
