F6 - Cool graph .. El Nino/La Nina Explainer .. added novice detail .. lol .. most notes are direct quotes .. i hope .. :)



El Nino characterized by variations in the T of the surface of the tropical eastern Pacific Ocean

* warmer = El Nino (due to lack of upwelling) .. weaker SE trade winds

* cooler = La Nina (typical upwelling) .. stronger trade winds

What causes water T changes?

Trade Winds .. SE winds .. at 2:53, TW territory? .. see horizontal on video .. across South America .. lower about 50% of Africa .. northernmost tip of Australia, 'bout Darwin up .. Indonesia .. http://en.wikipedia.org/wiki/Indonesia

( includes Borneo 73% in Indonesia http://en.wikipedia.org/wiki/Borneo and Sumatra ..

Sumatra (Indonesian: Sumatera) is an island in western Indonesia, westernmost of the Sunda Islands. It is the largest island entirely in Indonesia (two larger islands, Borneo and New Guinea, .. en.wikipedia.org/wiki/New_Guinea .. are shared between Indonesia and other countries) and the sixth largest island in the world at 473,481 km2 with a population of 50,365,538. Its biggest city is Medan with a population of 2,109,330. .. http://en.wikipedia.org/wiki/Sumatra )

and Malaysia, northernmost coast lands of Borneo .. http://en.wikipedia.org/wiki/Malaysia ..

back to video ..

weaker El Nino TWs basically warm water across entire tropical eastern Pacific Ocean Australia east to South America .. less warm water so less rain in Australia, bush fires, droughts .. floods, landslides Ecuador, Peru and others there, fish drought and death as fewer fish (economy heavily dependent on) nutrients in the South American south Pacific .. tropical cyclones in Tahiti, 'cuz air is virtually stagnant with no shear ..

Wind shear, sometimes referred to as windshear or wind gradient, is a difference in wind speed and direction over a relatively short distance in the atmosphere. Wind shear can be broken down into vertical and horizontal components, with horizontal wind shear seen across fronts and near the coast, and vertical shear typically near the surface, though also at higher levels in the atmosphere near upper level jets and frontal zones aloft. .. http://en.wikipedia.org/wiki/Wind_shear

coral devastation .. thanks El Nino ..

How does it affect the US?

The Jet Stream

* El Nino: situated W-E over northern Gulf of Mexico and Florida.

* La Nina: extends from the Eastern Rockies east-northeastward to the eastern Great Lakes.

El Nino .. a lot more storms and snow over the southeast and Texas area ..

La Nina .. storm tracks a lot more north, a Minnesota mention ..

see map at 6:47 .. > 40% wetter northeast, and southwest from Great Lakes .. drier along southern regions, especially Florida ..

lol .. F6, how's that for meat and potatoes? .. decently prepared and presented? .. the video i mean ..

.. sure hope it adds to some more understanding for others, too .. lol ..
