7. What are the hazards associated with a cyclone?
Those that form in the tropics may also be
calledhurricanes,typhoons, tropicalstorms, and
tropical depressions, depending on their size and
intensity. The main hazards associated
withtropical cyclonesarewind
gustsandheavyrainfall, but considerable
coastalerosionandstorm surgescan also
happen.

8. What is a cyclone storm?
A tropicalcycloneis a non-frontalstormsystem
that is characterised by a low pressure center,
spiral rain bands and strong winds. Usually it
originates over tropical or subtropical waters and
rotates clockwise in the southern hemisphere and
counter-clockwise in the northern hemisphere.

10. What is the cause of a tropical cyclone?
Tropical cyclonestypically form over
large bodies of relatively warm water.
They derive their energy through the
evaporation of water from the ocean
surface, which ultimately recondenses
into clouds and rain when moist air rises
and cools to saturation.

11. What are the effects of the cyclone?
The maineffectsof
tropicalcyclonesinclude heavy rain,
strong wind, large storm surges at
landfall, and tornadoes. The
destruction from a
tropicalcyclonedepends mainly on
its intensity, its size, and its location.

12. How is a cyclone formed?
A tropicalcycloneneeds two main
ingredients: a cluster of thunderstorms
and a warm body of water –at least
27ºC –from which the storm gathers its
energy. The warm, tropical ocean under
a developing storm evaporates then
condenses toformclouds, releasing
heat throughout the process.

13. Floods

19. What is the cause of a tornado?
The intense spinning of
atornadois partly the result of
the updrafts and downdrafts in
the thunderstorm (caused by the
unstable air) interacting with the
wind shear, resulting in a tilting
of the wind shear to form an
uprighttornadovortex.

20. How many different types of tornadoes are
there?
Types of Tornadoes.Tornadoescome from
mainly twotypesof thunderstorms: supercell
and non-supercell.Tornadoesthat come from
a supercell thunderstorm are the most
common, and often the most dangerous. A
rotating updraft is a key to the development of
a supercell, and eventually atornado.

21. What is the cause and effect of a tornado?
Tornadoesarecauseby the thunderstorms being
extremely large, unstable and with wind shear in the
lower region of the atmosphere. ... Firstly, when the
thunderstorm approaches, the wind direction, speed
changes in the upper area of the atmosphere
andcausesan invisible horizontal spinningeffectin the
lower region.

22. Monsoons
Amonsoonis a seasonal change in the
direction of the prevailing, or strongest,
winds of a region.Monsoonscause wet and
dry seasons throughout much of the
tropics.Monsoonsare most often associated
with the Indian Ocean.Monsoonsalways
blow from cold to warm regions.

23. How is the monsoon caused?
Themonsoon, which is essentially the seasonal reversal in
wind direction,causesmost of the rainfall received in India and
some other parts of the world. The
primarycauseofmonsoonsis the difference between annual
temperature trends over land and sea.

28. We can’t stop natural disasters but we can arm ourselves with
knowledge.
So many lives wouldn’t have to be lost if there was enough
disaster preparedness.
:be ready always in the time of natural disasters
: be updated
:don’t panic
:prepare all the emergency kit
:evacuate as early as possible
:ALWAYS PRAY TO GOD
IN TIMES OF DISASTER,BEING PREPARED WILL MAKE YOU SURVIVE .
