El Niño–Southern Oscillation

Index El Niño–Southern Oscillation

El Niño–Southern Oscillation (ENSO) is an irregularly periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting climate of much of the tropics and subtropics. [1]

Tahiti

Tahiti (previously also known as Otaheite (obsolete) is the largest island in the Windward group of French Polynesia. The island is located in the archipelago of the Society Islands in the central Southern Pacific Ocean, and is divided into two parts: the bigger, northwestern part, Tahiti Nui, and the smaller, southeastern part, Tahiti Iti. The island was formed from volcanic activity and is high and mountainous with surrounding coral reefs. The population is 189,517 inhabitants (2017 census), making it the most populous island of French Polynesia and accounting for 68.7% of its total population. Tahiti is the economic, cultural and political centre of French Polynesia, an overseas collectivity (sometimes referred to as an overseas country) of France. The capital of French Polynesia, Papeete, is located on the northwest coast of Tahiti. The only international airport in the region, Fa'a'ā International Airport, is on Tahiti near Papeete. Tahiti was originally settled by Polynesians between 300 and 800AD. They represent about 70% of the island's population, with the rest made up of Europeans, Chinese and those of mixed heritage. The island was part of the Kingdom of Tahiti until its annexation by France in 1880, when it was proclaimed a colony of France, and the inhabitants became French citizens. French is the only official language, although the Tahitian language (Reo Tahiti) is widely spoken.
