Thanksgiving equals turkey, pumpkin pie, cranberries, stuffing, basically a lot of eating. How much does all this food cost on average for a family? How many turkeys are consumed during this time of year? Well we have the answers to these questions and so many more for you. Like did you know that one of the first meals on the moon by these two astronauts was a turkey with all the trimmings? Yes Thanksgiving can even happen on the moon! Get ready to learn the answers to all the mysteries and joys of Thanksgiving.
about the formation and causes and impacts of the cyclone formation in the earth. and cyclone formed in the INDIA region whole about the briefly explained about cyclone
Hydrometeorological hazard is a process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.
2. Cyclones:
Cyclone refers to any spinning storm that rotates around a
low-pressure center.
Word "Cyclone" is derived from the Greek, word
"Cyclos" meaning the coils of a snake.
The low-pressure center is also referred to as the 'eye' of
the storm, which is well known for being calm compared
with the areas under the spinning 'arms' of the storm called
‘eye wall’
3. Formation of a Cyclone:
If the sea is warm (sea surface temperature > = 26.50 C)
Warm air likes to rise, and as it rises, it cools. Cool air can't
hold as much moisture as warm air, so that water gets
squeezed out of the condensing air and a cloud begins to
form. If the warm air rises very quickly, this creates
an updraft.
4. Likewise, if the water in the cloud builds up enough, it
may fall back to the ground as rain and draw cool air down
with it as a downdraft.
When they work together, that warm updraft and cool
downdraft create a storm cell. As this process continues,
the cloud grows and we eventually get a large
thunderstorm cloud.
5. This thunderstorm cloud is now ready to diversify into
other storms like tropical cyclones and tornadoes. But this
can't happen unless the air in the cloud starts spinning
horizontally. If this occurs over the tropical ocean, this is
called a tropical depression. This is like a baby tropical
cyclone, with wind speeds less than 39 mph.
If it starts spinning even faster and has wind speeds
between 40-73 mph, we have a tropical storm. If the
storm grows even larger over the tropical ocean and has
wind speeds above 74 mph, we have our full-grown
cyclone.

7. Tropical cyclones
Polar cyclones
Mesocyclone
Tropical cyclones are cyclones that occur over
tropical ocean regions. Based on their wind speeds
they are categorized 1, 2, 3, 4 or 5 increasing with
intensity and wind speed as the number increases.

12. Polar cyclones:
Polar cyclones are cyclones that occur in polar
regions like Greenland, Siberia and Antarctica. Unlike
tropical cyclones, polar cyclones are usually stronger in
winter months. As you can see, these storms really do
prefer the colder weather. They also occur in areas that
aren't very populated, so any damage they do is usually
pretty minimal.
13. Mesocyclone:
If the spinning occurs over land, we have
mesocyclone. If the mesocyclone gets spinning fast
enough that the cloud starts reaching toward the
ground like a long arm, this is the beginning of a
tornado.
'Meso' means 'middle', so you can think of this as the
mid-point between one type of storm and the other.

15. “For Development to be
Sustainable,
Disaster Mitigation Must be
Built Into
The Planning Process”
16. Make sufficient stock of foodgrains or food packets,
kerosene lanterns and other dry food commodities are
available for distribution to the victims.
A large number of people are likely to become
homeless as their houses may wash away or get
destroyed Hence make arrangements for proper shelter
material such as Talpatris, Tents, Water, Blankets,
Utensils, etc
Medical and Veterinary Departments should be fully
equipped with required Drugs and Vaccines for taking
preventive steps after cyclone and to arrest the spread
of epidemics.
17. All the Government vehicles should be kept in road-worthy
condition for putting them to use in the emergency.
State Electricity Board should take advance action
immediately to procure them when necessity arises.
Electricity Board should clear the roads of fallen electric
poles and restore power supply as quickly as possible.
Communications facilities are likely to get disrupted, (both
land and telecommunications) hence make immediate
arrangements for satellite phones, mobile phones, etc.
18. 'Cyclone stores' should be opened if possible
in each and every village or in variousTalukas
for distributing the relief material to the
respective villagers of that village.
The person incharge in the respective stores
should immediately report the NGO's or
Government officials for the emergency
requirements.
