many questions... El Niño is the warming of ocean currents that forms off the east coast of Peru. It was first discovered around Christmas time about 20 yrs ago (hence "El Niño in reference to Jesus).

By warming the waters above a certain natural temperature, natural currents start moving in 'out-of-normal' circulation patterns. The trade winds for one (coming in from the East), reverse or die out altogether. Water temperatures rise and create the havoc we have seen. El Niño appears every seven/eight years - sometimes more.
Sorry, I don't know what an Upwelling is but I imagine, being an ocean thing, it is greatly affected by El Niño as per description above.

Hope this has helped somewhat.

El Nino refers to when there is a lot of rain in western mexico which causes the south pacific ot go into a drought year which in turn can creat large forest fires in australia. La Nina is the opposite, when there is drought in mexico/the southwest and the southpacific gets a ton of rain.

Upwelling occurs when cold nutrient rich bottom ocean waters rise up to mix with warm ocean waters creating an abundance of life!!

El nino causes extreme upwelling in the mid lattitudes of the pacfic near the southern coast of mexico and the sea life goes nuts....

thats all i am willing to give...

And in case you imagine about it the in straightforward words challenge with YAP is really element-pastime enthusiasts whose handiwork can turn off novices & make older-timers truly careful to the point of creating YAP a drag. and that is possibly why you requested this q contained in the first position. for sure lots of the oldtimers recognize that this received't very last lengthy-i trust it wat battgirl who stated it & then chuffed (clean relaxing) days must be the following back. about survival, Pinoys are between the most suitable survivors contained in the international, so no doubt YAP will live to inform the tale, I in basic terms desire that each and each one human beings will be the following in both the sturdy circumstances & the undesirable.
