EL-NIÑO
**Part II of IV**
What Then Is AN EL-NIÑO?
During the fall in the Northern Hemisphere, the winds which are blowing
from east to west, (NORTHEAST TRADE WINDS), from the equator to about 30
degrees north latitude, in the Southern Hemisphere, the (SOUTHEAST TRADE
WINDS), from the equator to about 30 degrees south latitude, become weak
and by Christmas time are reversed, these winds and now blowing west to east,
from the area of Australia and Indonesia towards South America, or
from high pressure over the western tropical Pacific towards lower pressure
over the eastern tropical Pacific.
The winds blowing from west to east move the warm waters eastward, when
this occurs, The UPWELLING of the colder water rich in nutrients from
the depths of the Pacific Ocean weakens, or does not occur at all. This
lack of UPWELLING of colder water rich in nutrients causes a lack of food
for the fish and sea life in the area, thus the fish, seabirds and other
animal and wildlife which the phytoplankton and fish help support in the
food chain, migrate away from the area. Some sea life normally found in
these tropical waters migrate as far north to off the western coast of the
United States.
As the warm water moves eastward, it strikes the western coast of
South America, and then spreads out, when this happens, the sea level in the
eastern Pacific along the coasts of Ecuador and Peru rise about 1 foot,
likewise, the sea levels in the western Pacific lower by about a foot,
exposing and destroying any exposed coral reefs of the many islands in the
Pacific. These warm waters spread south along the shores of South America
and northward to off the western coast of the United States, and as far
north as Canada. Ocean water temperature at the surface rise over 10
degrees from normal levels of 70 Degs. F. to well into the 80s.
In the future look for weather articles on: Hurricanes. Tornadoes.
Floods. Thunderstorms. Winds. Radar. Atmosphere. Orographic Lifting.
Adiabatic Process. Clouds. Relative Humidity. Water. Temperature and
Temperature Scales, and many more.
