**EL-NIÑO**
Bath,Pa.
**Part I of IV**
What is this phenomenon called El-NIÑO
EL-NIÑO is Spanish meaning Christ Child. Every year around
Christmas time, this phenomenon occurs in the Pacific Ocean off the
shores of Peru and Ecuador, South America, and along the equator
westward to Australia and Indonesia. This phenomenon combines the
tropical atmosphere and tropical ocean waters of the Pacific Ocean.
At this time it is not certain which of the two dominate, and was
given the name EL-NIÑO by the Peruvian fishermen.
Normally high pressure is located in the eastern Pacific off the
shores of Ecuador and Peru, likewise, low pressure is situated over
the western Pacific in the area of Indonesia and Australia. This
produces winds that flow east to west, know as the Northeast Trade
Winds, from high to lower pressure.
The wind blowing from east to west, (high to low pressure)
causes the warm surface water to also move from east to west. As the
water moves towards Indonesia and Australia, colder waters, rich in
nutrients, rise from the depths of the ocean to replace the warmer
surface water, this is know as (UPWELLING). UPWELLING occurs along
narrow corridors which run east to west along the equator, and off
the coast of Ecuador and Peru, and are 100 to 200 miles wide.
The water rising from the depths of the ocean, some 500 to over
3,000 feet below the surface is rich in nutrients, and replaces the warmer
surface waters which are moving westward. The abundance of these rich
nutrients enhances the growth of (Phytoplankton), which in turn support a
high amount of fishery. When these conditions prevail, fish are abundant in
these waters and fishing is at its best, producing some of the worlds
largest fish catches for the Peruvian Fisherman. At one time, the Peruvian
anchovy fishing was one of the largest in the world. Before over fishing,
the annual anchovy catch at time topped over 10 million tons.
The EL-NIÑO phenomenon occurs every year around Christmas time, and
generally last from 2 to 3 months, this is considered to be an average
or weak EL-NIÑO. Every so many years a strong EL-NIÑO will start earlier
in the fall and last well into late spring or early summer in the Northern
Hemisphere, late fall and early winter in the Southern Hemisphere.
