In the El Nino effect, the sea surface temperature becomes much higher than normal. This temperature can be 4 to 5 degree Celsius higher than normal. El Nino is a part of the climate system. It has a profound effect on the weather. Due to its arrival, there is an effect on the weather all over the world.
In the La Nina effect, the sea surface temperature drops significantly. It has a direct effect on the temperature around the world and the temperature becomes colder than average. During this period in India, it is very cold and the rains are also moderate.
The duration of the La Nina event is between one to three years whereas, El Nino continues for less than a year.
