The other land masses in Polynesia — New Zealand, Norfolk Island, and Ouvéa, the Polynesian outlier near New Caledonia - are the unsubmerged portions of the largely sunken continent of Zealandia. Zealandia is believed to have mostly sunk below sea level 23 million years ago, and recently partially resurfaced due to a change in the movements of the Pacific Plate in relation to the Indo-Australian plate .

In French Polynesia, a vast archipelago in the South Pacific Ocean, the climate is tropical, influenced by the south-east trade winds, with a hot and humid season from November to April and a cooler season from May to October.The hot season is also the rainiest, in addition, from December to April, there's the risk of cyclones (except on the Marquesas Islands).

French Polynesia is affected by two separate patterns of cyclones: the south easterly moving storms and the “recurving” storms that begin forming near the Marquesas and steer southwesterly before recurving to steer southeasterly.

The depressions giving rise to cyclones generally form in the ZCPS, in the north-west of Polynesia. They then follow a path towards the South-East, as shown by the trajectory of Cyclone OLI (2010). In El Nino years these trajectories originate further east than in normal years and circulate between the Society Archipelago and the Cook Islands.

What is a Cyclone? In meteorology, it refers to a large-scale air mass that revolves around a strong low atmospheric pressure centre. We can characterize cyclones by spiralling inward winds rotating around a low-pressure zone. In this topic, we will explain how are cyclones formed and its causes and effects.

Can a tropical cyclone form without an updraft?

  • When that dry air is forced into the system by strong mid/upper-level winds, much more substantial evaporational cooling can occur which often leads to the total collapse of thunderstorm updrafts. Without persistent updrafts leading to persistent latent heat release, you can’t get a tropical cyclone to form.
