When the easterly trade winds strengthen during La Nina it pushes
water along the equator from the east to west.
When the wind - driven ocean circulation is intense, such as during the negative phase of the IPO & La Nina, there is strong upwelling of cold deep
water along the equator, and along the eastern coasts of the continents.

El Nino's mass of warm
water puts a lid on the normal currents of cold, deep
water that typically rise to the surface
along the
equator and off the coast of Chile and Peru, said Stephanie Uz, ocean scientist at Goddard Space Flight Center in Greenbelt, Maryland.
The band of cold
water off Chile's coast is produced by the Humboldt Current, a slow northerly ocean flow that runs more than 3,000 miles
along the Pacific coast of South America, from southern Chile all the way to the
equator.
Intense trade winds and strong uppwelling
along a region near the
equator, known as the cold tongue and caused by Ekman pumping, bringing up cold and nutrient
water from the deep sea.
Constellation Pisces (the Fish) is faint but can be found
along the celestial
equator swimming north of Aquarius (the
Water Bearer) and Cetus (the Whale or Sea Monster) and surrounded by Pegasus, Andromeda, Triangulum, and Aries.
In the tropical Pacific, the distance from Indonesia to South America and the way tropical winds push warm
water west combine to allow special waves to travel
along the
equator and are amplified by the atmospheric wind response to produce large fluctuations in temperatures (up to 3 degrees Celsius) in the Eastern Pacific that last for months.
Temperate
waters flow northward
along the coastline from the
equator with the Gulf Stream, bringing an array of excellent game fish with them.
One other factor here is increased evaporation at the
equator which has increased the salanity of tropical
waters along with increased percipitation at the poles seems to be making the thermohaline system move faster which in turn carries move heat to the poles and hence increases polar ice melting and hence possibly a greater chance of slowdown of the thermohaline system.
Intense trade winds and strong uppwelling
along a region near the
equator, known as the cold tongue and caused by Ekman pumping, bringing up cold and nutrient
water from the deep sea.
After 30 + million years of cooling, 2 to 3 million years ago, colder ocean
waters eventually upwelled in the mid latitudes
along the west coasts of major continents as well as
along the
equator.
(Page 384) The cold, saltier
water sinks and starts moving back towards the
equator along the bottom of the ocean.
It is an harmonic oscillation of ocean
water from side to side
along the
equator.»
The cold, saltier
water sinks and starts moving back towards the
equator along the bottom of the ocean.
It runs ashore at the
equator, spreads north and south
along the coast, and warms the
water and the air above it.
As it skirts
along the East Coast of Australia it carries a large amount of warm tropical
water from the
equator southward.
El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor
water to the south; does not usually extend farther than a few degrees south of the
Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures
along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing
El Niño is a warming of the eastern Pacific Ocean mainly
along the
equator, but more broadly, those warm
waters trigger profound events across half the planet, including heavy rains in California, fires in Australia, and more and stronger typhoons in the western Pacific.
As the winds blow west
along the
Equator, they push warm
water ahead of them, piling it up in a warm pool in the western Pacific.
When that warm
water reaches the western Pacific it rises and, in the main, tracks back
along the
equator in the upper atmosphere and loses its heat to space.
Again, the America's stand in the way of a free circumpolar circulation and some colder
waters must be diverted
along the East coast towards the
Equator.
The long blue La Nina line at the
equator is upwelled and / or kicked
along the South American coast from the South
water.

Stronger downward transport of
water mass must be balanced by upwelling somewhere else, and this occurs in regions of divergence (Ekman suction)-
along the equatorward travelling arms of the gyres, and
along the
equator itself.
This upwelling creates a cold tongue of
water that extends
along the
equator from Peru to the International Dateline (180 ° longitude east).
