What are El Niño and La Niña? | American Geosciences InstituteIt is a warming of the central to eastern tropical Pacific Ocean. Yes, the last episode began just two years ago, in They both tend to develop during the spring March-June , reach peak intensity during the late autumn or winter November-February , and then weaken during the spring or early summer March-June. In turn, changes in the atmosphere impact the ocean temperatures and currents. Further research will help separate the natural climate variability from any trends due to human activities. The humanitarian fallout in certain areas included increased food insecurity due to low crop yields and rising prices; higher malnutrition rates; devastated livelihoods; and forced displacement. Excessive rainfall also triggered and exacerbated outbreaks of waterborne diseases such as cholera and typhoid as well as vector-borne diseases such as malaria.

It was the second-coolest year of the 21st century to date, and tied with the second-warmest year of the 20th century.

Such events are a consequence of strong and extensive interactions between the ocean and atmosphere. They are associated with widespread changes in the climate system that last several months, and can lead to significant socio-economic impacts affecting infrastructure, agriculture, health and energy sectors for example. These episodes alternate in an irregular inter-annual cycle called the ENSO cycle. The name 'ENSO' is a reminder that close interaction between the atmosphere and ocean is an essential part of the process. While the global climate system contains many processes, ENSO is by far the dominant feature of climate variability on inter-annual timescales.
