El
Niño means The Little Boy or Christ Child in Spanish. El Niño origin was
found by a group of fishermen who were off the coast of South America in the
1600s, they noticed the appearance of the unusual warm water in the Pacific
Ocean.
El Niño is a periodic event in which sea surface temperatures in the
central and eastern Pacific Ocean is getting warmer. It is described as a warm
ocean phase. At this point, the poor-nutrient warm water in place of cold
water containing nutrient-rich nutrients in the Pacific region. There is cold phase alternating with El Nino. It was named La Niña. La Niña means The
Little Girl in Spanish. La Niña is also sometimes called El Viejo, anti-El
Nino, or simply "a cold event". Episodes of El Niño and La Niña usually
will last for 9 to 12 months. However, there are a number of events of this
phenomenon lasting for years. This phenomenon occurs at irregular intervals of
two to seven years. Typically, El Niño occurs more often than La Niña.
The hot temperature in the middle of the Pacific Ocean has caused a high
evaporation occurs and the result is two different wind processed where the
winds bring plenty of water and another one is lesser. This phenomenon effected the east coast islands of Indonesia and Australia to receive water
that is not much. The wind in the area is also dry. Malaysia is located near
Pacific Indonesia and Malaysia also affected by El Niño.
Malaysia has
experienced this phenomenon in 1998, where the highest temperature is 40.1
degrees Celsius was recorded at Meteorological Station Chuping, Perlis. The
last time Malaysia was hammered by El Niño in 2009 and 2010 with a moderate
rate. According to Director of National Antarctic Research Centre (NARC)
Universiti Malaya, Prof Datuk Dr Azizan Abu Samah said in terms of predictions
that have been made, more than 80 percent probability indicates that El Nino
will last until 2016.
This
natural phenomenon of climate change will cause a chain where some areas will
experience heavy rainfall, while some areas will experience drought. In
Malaysia, this phenomenon will lead to Malaysia increased by 0.5-2.0 degrees
Celsius temperature. Rainfall will also be reduced by 20-60% and will probably
resemble as 1997. The temperature is too hot and the rainfall is less likely to
cause the water level in the dam will decrease dramatically resulting in a
severe water crisis. So the government had to implement water rationing. Forest fires also occurs regularly and causez haze and pollution. During prolonged drought the crop will be the most effected.
