This document provides information about different types of storms and clouds. It discusses hurricanes, typhoons, and the difference between them. Tropical cyclones are described as rotating storms that form over warm ocean waters and have a low pressure center. Cirrus, cumulus, cirrocumulus, stratocumulus, and nimbus clouds are defined. Common weather instruments like anemometers, wind vanes, thermometers, rain gauges, and barometers are also outlined. Convergence is defined as an atmospheric condition where air flows horizontally into a region, is forced to rise, and causes low pressure systems.

1. TYPHOONS AND
WARNINGS

2. Television
• A television has a
number of uses. It can
either entertain,
inform and educate
you. But you have to
bear in mind that not
all you see in tv shows
are all good for you.

3. TROPICAL
CYCLONES
• A tropical cyclone is a rapid
rotating storm originating over
tropical oceans from where it
draws the energy to develop. It has
a low pressure centre and clouds
spiraling towards the eyewall
surrounding the "eye", the central
part of the system where the
weather is normally calm and free
of clouds.

5. Hurricanes
• A hurricane is a type of storm called a tropical cyclone, which
forms over tropical or subtropical waters.
• Hurricanes originate in the Atlantic basin, which includes the
the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, the
eastern North Pacific Ocean, and, less frequently, the central
central North Pacific Ocean.

6. TYPHOON
• A typhoon forms when winds blow into areas of the ocean where
the water is warm. These winds collect moisture and rise, while
colder air moves in below. This creates pressure, which causes the
winds to move very quickly. The more warm-air and moisture there
is, the more intense the winds.

7. What is difference between
typhoon and hurricane?

8. • The only difference between a hurricane and a typhoon is
the location where the storm occurs.
• If it's above the North Atlantic, central North Pacific or eastern North
Pacific oceans (Florida, Caribbean Islands, Texas, Hawaii, etc.), we
call it a hurricane. If it hovers over the Northwest Pacific Ocean
(usually East Asia), we call it a typhoon.

9. Cloud Watch

10. Cirrus clouds
• Cirrus clouds are short, detached, hair-like clouds found at high altitudes.
These delicate clouds are wispy, with a silky sheen, or look like tufts of
hair. In the daytime, they are whiter than any other cloud in the sky. While
the Sun is setting or rising, they may take on the colours of the sunset.

11. CUMULUS CLOUDS
• Cumulus clouds are detached,
individual, cauliflower-shaped
clouds usually spotted in fair
weather conditions. The tops of
these clouds are mostly brilliant
white tufts when lit by the Sun,
although their base is usually
relatively dark.

12. CIRROCMULUS
CLOUDS
• Cirrocumulus can often show up
ahead of a warm front and is a
usually a decent indicator that the
weather is about to change. When
these high clouds take and the
barometric pressure begins to fall,
usually that means that precipitation
associated with a disturbance is
likely about 6 to 12 hours away

13. Stratocumulus
Clouds
• Most often, stratocumulus
produce no precipitation,
and when they do, it is
generally only light rain or
snow. However, these
clouds are often seen at
either the front or tail end of
worse weather, so they may
indicate storms to come, in
the form of thunderheads or
gusty winds.

14. No Clouds
• No clouds means no rain, ice, or
snow. That means drinking-water
supplies wouldn't get replenished.
Water shortages also spell trouble
for power plants that rely on heating
fresh water. Without clouds to
reflect light from the sun, global
temperatures would spike.

15. Nimbus Clouds
• A nimbus cloud is a cloud
that produces precipitation.
Usually, the precipitation
reaches the ground as rain,
hail, snow, or sleet. Falling
precipitation may evaporate
as virga. Since nimbus
clouds are dense with
water, they appear darker
than other clouds.

17. ANEMOMETER
An anemometer is an
instrument that
measures wind speed.

18. Wind Vane
A wind vane is
an instrument used to
show the direction the
wind is blowing from

19. Thermometer

20. Rain Gauge
Is an instrument used to
collect and measure
precipitation (falling
water).

21. Barometer
• A barometer is a scientific instrument used
to measure atmospheric pressure, also called
barometric pressure

27.  Convergence is an atmospheric condition that exists when
there is a horizontal net inflow of air into a region. When air
converges along the earth's surface, it is forced to rise since
it cannot go downward. At the surface, low pressure systems
have a counter clockwise rotation in the Northern
Hemisphere, with the wind turning slightly inward towards
the lowest pressure. This causes air to converge, or come
together, at the center of the low near the ground. Since the
converging air has nowhere else to go, it rises.
