La Nina

La Nina is caused due to the cooling of Pacific Ocean. It is considered as the counterpart of El Nino. Together La Nina and El Nino contribute to the El-Nino Southern Oscillation, called the ENSO. Scientists use Oceanic Nino Index to measure the deviation from the normal sea surface temperatures. La Nina is identified with the decrease in surface sea temperatures of more than 0.5 degrees Celsius for consecutive 3-month seasons.
