MANAGEMENT
OF CYCLONES
CONTENTS :
 What Are Cyclones ?
 Structure & Formation.
 Categorization.
 Major Factors Responsible For Cyclone Disaster.
 Preventions To Be Taken Before, During & After Cyclones.
A cyclone is an area of low atmospheric pressure
characterized by inward spiraling winds that rotate
counter clockwise in the northern hemisphere and
clockwise in the southern hemisphere of the Earth.
A cyclone is an area of low atmospheric pressure

DEFINITION
CYCLONE'S ARE NAMED VARIOUSLY IN VARIOUS
REGIONS
 A tropical cyclone is the general term for violent circular winds
with torrential rains that originate in the tropics.
 Hurricanes is the term when they occur in the Atlantic Ocean
 They are called typhoons in the Pacific Ocean.
 They are called cyclones in the Indian Ocean.
STRUCTURE AND FORMATION: 
• The structure of the cyclone
consists of northern
hemisphere, center and
southern hemisphere. Usually
a cyclone hits where there is
low atmospheric pressure and
the low atmospheric pressure
are mostly found in tropical
and sub-tropical regions.
FORMATION OF CYCLONE : 
• Cold- core cyclones:
 These cyclones form due to the motion of a cyclone. The
pressure here increases upwards and low surface pressure.
• Warm-core cyclones:
 It starts due to the upper pressure and as the cyclone forms it
increases its strength.

A cyclone is an area of low atmospheric pressure characterized by inward spiraling winds that rotate counter clockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth. DEFINITION
  • 4. CYCLONE'S ARE NAMED VARIOUSLY IN VARIOUS REGIONS  A tropical cyclone is the general term for violent circular winds with torrential rains that originate in the tropics.  Hurricanes is the term when they occur in the Atlantic Ocean  They are called typhoons in the Pacific Ocean.  They are called cyclones in the Indian Ocean.
  • 5. STRUCTURE AND FORMATION:  • The structure of the cyclone consists of northern hemisphere, center and southern hemisphere. Usually a cyclone hits where there is low atmospheric pressure and the low atmospheric pressure are mostly found in tropical and sub-tropical regions.
  • 6. FORMATION OF CYCLONE :  • Cold- core cyclones:  These cyclones form due to the motion of a cyclone. The pressure here increases upwards and low surface pressure. • Warm-core cyclones:  It starts due to the upper pressure and as the cyclone forms it increases its strength.
  • 9. Polar cyclones: • Polar cyclones: Polar cyclone is a low pressure weather system usually spans up to 1,000 to 2,000kms in which the area circulates in a counter clockwise direction in northern hemisphere and clockwise in southern hemisphere.
  • 10. POLAR LOW •  Polar low: This is found over ocean areas. It has a horizontal length scaling less than 1,000kms and exists no more than a couple of days. They are difficult to detect using conventional weather reports, which is hazardous for shipping, gas and oil plat forms.
  • 11. SUB-TROPICAL CYCLONE • Sub-tropical: These cyclones have the characteristics of tropical cyclones. It can be formed in a wide band of latitude from the equator to 50 degrees.
  • 12. Tropical cyclones: • Tropical cyclones:  A tropical cyclone is the storm system fueled by the heat released when moist air rises and the water vapour in it condenses.
  • 13. EXTRATERRESTRIAL CYCLONES • This cyclone is found on mars by the Hubble space telescope. These are not unique to earth. These cyclones are common on Jovian planets like the small dark spots on Neptune, Mars.
  • 15.  Major Factors Responsible For Cyclone Disaster: • Manifestation of humanity:  Manifestation of humanity overloading the earth’s ecology due to global warming is a reality that cannot be neglected. The human effect on the climate is the major factor leading to cyclone.  Ecological impacts are of various kinds like: 1: Use of land. 2: Use of water. 3: Effects on bio-diversity. 4: Use of non-renewable resources. 5: Production of green house gases. 6: Production of other un acceptable pollutants.
  • 16. Cont’d……. • Destruction:  The destruction, during recent decades, of coastal forests removed a barrier  which formerly mitigated the effects of waves and wind from cyclonic  storms.  • Poverty:   The standard of protection such as housing and infrastructure in an  inappropriate way for a region subject to frequent intense cyclones. And for  poor people, without savings or insurance, total loss turns a disaster into a  catastrophe.
  • 17. PEOPLE’s SUFFERINGS AND SORROWS AT THE TIME OF CYCLONE
  • 23. • Keep a list of emergency phone numbers handy, including numbers for your local Police, Fire, Ambulance, State Emergency Service, etc.. • Clear your property of any loose items that could become missiles during extreme winds (eg sheet iron and wood). • Find out how and where to turn off power, gas and water supplies. Store your important documents (eg wills, passports, photos, birth certificates) in a fire/water-proof container or safe deposit box. • Check that you have adequate household and contents insurance and which hazards are not covered by the policy. Prevention To Be Taken Before A Cyclone:
  • 24. • Disconnect all electrical appliances and turn off the gas . • Fuel your car and park it under solid cover. • Pack an evacuation kit including your emergency kit, warm clothing, essential medications, valuables, papers, photos and keepsakes in waterproof bags. • Stay inside and shelter in the strongest part of the building. Continue to listen to your portable radio for updates and advice. • Beware of the calm 'eye' of the cyclone. If the wind suddenly drops, don't assume that the cyclone is over. Violent winds will soon resume from the opposite direction . • If you are driving, STOP - but well away from the sea and clear of trees, power-lines and watercourses. Stay in your vehicle. Prevention At The Time When Cyclone Hits:
  • 25. • Don't go outside until officially advised it is safe to do so. • Check for gas leaks and don't use electrical appliances if wet. • Keep listening to your local radio for official warnings and advice. • If you did evacuate your home, don't return until advised. • Beware of fallen power lines, damaged bridges, buildings and trees, and don't enter floodwaters. Don't make any unnecessary telephone calls. Preventions To Be Taken After Cyclone:
