El Ni帽o 2015/2016: Impact Analysis of Past El Ni帽os

This report analyses El Ni帽o events over the last 35 years and identiies regions where there is an increased likelihood of an impact occurring

Abstract

El Ni帽o 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 鈥榢ick鈥�, to the climate system and can affect weather patterns globally. This report analyses El Ni帽o 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 Ni帽o 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 Ni帽o, scenarios for types of El Ni帽o 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.
