El-nino~~??

El Niño is an oscillation of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe.

when i was wathching the news , i have heard tis new word~

confusing so check n find some informaton about this ~~

intereting to read n i m gained knowledge about this

"During El Niño (bottom panel of the schematic diagram), the trade winds relax in the central

and western Pacific leading to a depression of the thermocline in the eastern Pacific, and an

elevation of the thermocline in the west. The observations at 110W show, for example, that

during 1982-1983, the 17-degree isotherm dropped to about 150m depth. This reduced the

efficiency of upwelling to cool the suface and cut off the supply of nutrient rich thermocline water

to the euphotic zone. The result was a rise in sea surface temperature and a drastic decline in

primary productivity, the latter of which adversely affected higher trophic levels of the food

chain, including commercial fisheries in this region. The weakening of easterly tradewinds during

El Niño is evident in this figure as well. Rainfall follows the warm water eastward, with

associated flooding in Peru and drought in Indonesia and Australia. The eastward displacement

of the atmospheric heat source overlaying the warmest water results in large changes in the

global atmospheric circulation, which in turn force changes in weather in regions far removed

from the tropical Pacific.

this phenomena in malaysia will continue until tis september( according news berita tv3)

i hope it wont too long as the weather is become much hotter than ever~~
