What is El Nino?
El Nino is a phenomenon of breaking the
normal condition of the ocean system - the
atmosphere in the tropical Pacific Causes
affect weather on a global scale.

Not El Nino occurs

Why is El Nino?
El Nino is the result of
the interaction of the
sea surface in the
tropical Pacific
atmospheric layer
just above it. This
phenomenon is
caused by interal
forces between two
surfaces: “ocean +
atmosphere”.

El Nino forms in Pacific waters

The change in air pressure, heating up the Earth,
or even the seabed earthquake, volcanic

Width of the Pacific is
also one of the
causes of the
phenomenon of El
Nino was born
El Nino typically does
not occur regularly,
but are in a cycle
from 2-7 years. Each

El Nino caused the
impact?
Rainstorms, flooding, which is the most visible
phenomenon of El Nino. Occur in countries of
South America, Romania, Bulgaria, or Russia's
Black Sea coast. Because of warm currents in
the eastern Pacific along the Chile, Peru ...
pushed into the air a huge amount of water
vapor. Create an unusual amount of rain,
sometimes up to 15 cm of rainfall per day.

El Nino causes storm in U.S.

Drought occurred in the
countries of the Eastern
Hemisphere. Countries
often influenced by the
El Nino drought caused:
Australia, Philippines,
Indonesia, Thailand,
Vietnam ... By focusing
on a cloudy area with
high density. Therefore,
the rest of the world
have suffered severe
droughts.

El Nino appears hot and dry

However, El Nino is not
always cause disaster for
humans. More than
5,000 years ago, when
this new phenomenon is
discovered, Peruvian
fishermen El Nino means
"good news". Since then
rising sea warm enough
for microbial growth.
They are food for fish. So
that the fishing of coastal
South American countries
to develop strong.

Consequences
In 1997, in South American countries lost an
estimated $ 96 billion due to storms, floods from
El Nino caused.
In Australia has made millions of kangaroos,
sheep and cows ... dying of thirst. New South
Wales for nine months without rain, freshwater
lakes Hinze (Queensland) exhausted. In Thailand,
more than a million homes were severely
dehydrated.

died of thirst

Shortages in Thailand drinking

Do great damage to people, economic disaster and especially social damage can not fix the
environment.

The response

Scientists have proposed
three solutions to deal with
this phenomenon:
Accurately forecast the time
of appearance, and health
forecast path of destruction.
No deforestation, carbon
dioxide emissions into the
air, because of El Nino
stronger ground if the lack
of trees or to the
greenhouse phenomenon
occurs.

Float building evacuation route (for flood zone)
or to store water (for dry regions).
