The 2015–16 South Pacific cyclone season is the period of the year when most tropical cyclones form within the South Pacific Ocean to the east of 160°E. The season officially runs from November 1, 2015 to April 30, 2016, however a tropical cyclone could form at any time between July 1, 2015 and June 30, 2016 and would count towards the season total. During the season, tropical cyclones will be officially monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji and the Tropical Cyclone Warning Centers in Brisbane, Australia and Wellington, New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) will also monitor the basin and issue unofficial warnings for American interests. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the basin while the JTWC designates significant tropical cyclones with a number and a P suffix. RSMC Nadi, TCWC Wellington and TCWC Brisbane all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds over a period of ten minutes, while the JTWC estimated sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).

Tropical Depression Raquel

Tropical depression (Australian scale)
Tropical storm (SSHWS)
 
DurationJuly 2 (Entered basin) – July 4 (Exited basin)
Peak intensity45 km/h (30 mph) (10-min);
998 hPa (mbar)

As the 2014-15 tropical cyclone year ended on June 30, Tropical Depression 17F, moved westwards out of the South Pacific basin and into the Australian region.[1][2] The system subsequently intensified into a tropical cyclone and was named Raquel, by the Brisbane Tropical Cyclone Warning Centre as it impacted the Solomon Islands.[3] The system subsequently started to weaken and move eastwards during July 1, before it crossed 160°E and back into the South Pacific Basin as a tropical depression during the next day.[1][4][5]

Tropical Depression 01F

Tropical depression (Australian scale)
Tropical storm (SSHWS)
 
DurationJuly 29 – August 4
Peak intensity65 km/h (40 mph) (1-min);
1000 hPa (mbar)

During July 29, RSMC Nadi reported that Tropical Disturbance 01F had developed, about 920 km (570 mi)* to the north-northeast of Honiara on the Solomon Island of Guadalcanal.[6] The system lied to the north of an upper level subtropical ridge of high pressure in an area of moderate vertical wind shear.[6] Over the next couple of days the system slowly organised further as it steered south-eastwards into an area of decreasing vertical wind shear.[7] As a result of further organization it was classified as a tropical depression during August 1.

Storm names

See also: Lists of tropical cyclone names

Within the Southern Pacific a tropical depression is judged to have reached tropical cyclone intensity should it reach winds of 65 km/h, (40 mph) and it is evident that gales are occurring at least halfway around the center. With tropical depressions intensifying into a tropical cyclone between the Equator and 25°S and between 160°E - 120°W named by the RSMC Nadi. However should a tropical depression intensify to the south of 25°S between 160°E and 120°W it will be named in conjunction with RSMC Nadi by TCWC Wellington. Should a tropical cyclone move out of the basin and into the Australian region it will retain its original name and vice versa.[2]

Season effects

This table lists all the storms that developed in the South Pacific to the east of longitude 160°E during the 2015–16 season. It includes their intensity on the Australian tropical cyclone intensity scale, duration, name, landfalls, deaths, and damages. All data is taken from RSMC Nadi and/or TCWC Wellington, and all of the damage figures are in 2015 USD.
