El Niño 2015/2016: Impact Analysis of Past El Niños


El Niño conditions are currently present in the Pacific and are forecast to develop into a strong event peaking later this year. Events such as this are a significant perturbation, or ‘kick’, to the climate system and can affect weather patterns globally. This report analyses El Niño events over the last 35 years and aims to identify regions where there is an increased likelihood of an impact occurring. This analysis is based on past analogous events and is not a prediction for this year.

After the brief introduction, Section 2 describes El Niño and discusses what is expected during 2015-16, providing a summary of current forecasts. Section 3 provides a summary of the historical global impacts of El Niño, scenarios for types of El Niño and looks at global changes in probability of extremes. Section 4 considers impacts by region and country: Southern Africa, West Africa, east Africa, Central Africa, Middle East and Northern Africa (MENA), Indonesia, Southern Asia, Southeast Asian Peninsula, Caribbean, and British Overseas Territories.
