The Correct Answer is All statements are correct.

• The Spanish immigrants called it El Nino, meaning “the little boy or Child Christ” in Spanish.
• El Nino refers to the unusual warming of the central and east-central equatorial Pacific Ocean which affects global weather.
• The warmer waters of the Pacific Ocean cause the winds in various regions to reverse, like the trade winds that come towards India.
• This change of wind direction leads to warmer winters and summers and a decrease in rainfall during the monsoon.
• Most of the time, it also leads to drought.
• El Nino soon came to describe irregular and intense climate changes rather than just the warming of coastal surface waters.
• When coastal waters become warmer in the eastern tropical Pacific (El Nino), the atmospheric pressure above the ocean decreases 
• La Nina
  • There is also an opposite of an El Nino, called La Nina means The Little Girl in Spanish.
  • This refers to times when waters of the tropical eastern Pacific are colder than normal and trade winds blow more strongly than usual.
  • Collectively, El Nino and La Nina are parts of an oscillation in the ocean-atmosphere system called the El Nino-Southern Oscillation, or ENSO cycle.
