Australian region tropical cyclone seasons
2019–20, 2020–21, 2021–22, 2022–23, 2023–24

The 2021–22 Australian region cyclone season is the period of the year when most tropical cyclones form in the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. The current season began from 1 November 2021 and will end on 30 April 2022, however, a tropical cyclone could form at any time between 1 July 2021 and 30 June 2022 and would count towards the season total. During the season, tropical cyclones will be officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the Australian Bureau of Meteorology, National Weather Service of Papua New Guinea and the Indonesian Agency for Meteorology, Climatology and Geophysics. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and the Fiji Meteorological Service will also monitor the basin during the season.

Season summary

Cyclone RubyTropical cyclone scales#Comparisons across basins

A tropical low developed to the north of the Western Region on 9 November, starting the season and the overall Southern Hemisphere season as well. After passing near the Cocos Islands with rainfall, it exiting the basin into the South-West Indian Ocean region on 14 November. Three days later, Tropical Low 02U formed near the Christmas Island and later became Tropical Cyclone Paddy, the first named cyclone in this season. On 22 November Tropical Low 03U formed and it exited the basin on 28 November.

Systems

Tropical Cyclone Paddy

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
Duration18 November – 25 November
Peak intensity75 km/h (45 mph) (10-min);
995 hPa (mbar)

On 16 November, the BoM first highlighted a possibility of another weak tropical low near or due west of Christmas Island. The agency also noted that this system may bring heavy rainfall to the island.[1] This became true when on the next day, the bureau noted that Tropical Low 02U developed from a trough at 100 kilometres (62 mi) to the northwest of the aforementioned territory under the influence of the weak Madden–Julian Oscillation in the basin.[2][3][4] On the next day, it became slow-moving as it meandered near the territory before resuming its movement eastwards to southeast.[5][6] On 21 November of 04:00 UTC, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) for Invest 90S which the agency was tracking very recently.[7] By 03:00 UTC of 22 November, the BoM upgraded the tropical low to a Category 1 tropical cyclone on the Australian scale and named it Paddy, becoming the first named cyclone in this season.[8][9] The JTWC later did the same thing at 09:00 UTC.[10]

At this time, it started to incline south-southeastwards with its pressure bottoming to 997 mbar (29.44 inHg). Three hours later, the BoM noted that Paddy continued to organize, with gale-force winds circling along its western and southern sides, according to scatterometer passes. The agency also nudged the system's intensity to 40 kn (75 km/h; 45 mph), which would eventually be Paddy's eventual maximum 10-minute sustained winds. Sea surface temperatures around 28 °C (82 °F), low wind shear and favorable upper-level divergence were the factors behind Paddy's intensification.[11] Convection started to decrease by 12:00 UTC; however, it managed to maintain its sustained wind speed as Paddy turned towards the south.[12] Early on the next day, dry air started to affect the storm, leading to Paddy's further disorganization as the system turned west-southwestwards and southwestwards.[13] As it moved west-northwestwards, it started to weaken and as it turned further westwards by 18:00 UTC of 23 November, the BoM issued its final warning as Paddy weakened into a tropical low.[14][15] On the next day the JTWC issued a final warning.[16] The BoM still tracked the system until 26 November.

Tropical Cyclone Teratai

Category 1 tropical cyclone (Australian scale)
Tropical storm (SSHWS)
 
Duration30 November – 11 December
Peak intensity65 km/h (40 mph) (10-min);
998 hPa (mbar)

On 29 November, BoM predicted a formation of a tropical low which they designated as 05U.[17] On the next day, 05U formed which was located adjoining regions to the Christmas Island and the island of Java.[18] At 23:30 UTC of the same day, the JTWC issued a TCFA for the system as the agencies found that the convection in associated with the system had increased.[19] At 09:00 UTC, the JTWC upgraded the system to a tropical storm, as it briefly attained sufficient convection.[20] Later, the BoM briefly upgraded it to a Category 1 tropical cyclone on the Australian scale at 12:00 UTC of 1 December, and named it Teratai which was given by TCWC Jakarta.[21] But at 18:00 UTC, the BoM downgraded to a tropical low as deep convection had become limited, with the LLCC displaced towards the south. This was caused due to the lack of sufficient outflow caused by the northerly strait line flow which inhibited the system from further intensifying, despite favorable conditions.[22][23] The JTWC followed the suite two hours later.[23] During the next few days, the BoM monitored ex-Teratai for redevelopment as the system executed a clockwise loop.[24] On 6 December the JTWC issued a TCFA,[25] and the next day it re-upgraded the system to a tropical storm.[26] However, by 09:00 UTC of 9 December, JTWC issued its final warning.[27] The BoM continued to track the system until 11 December.[28]

Tropical Cyclone Ruby

Category 2 tropical cyclone (Australian scale)
Category 1 tropical cyclone (SSHWS)
 
Duration10 December – 13 December (Exited basin)
Peak intensity110 km/h (70 mph) (10-min);
982 hPa (mbar)
Main article: Cyclone Ruby

On 6 December, the BoM predicted that a tropical low could form near the Solomon Sea.[29] Two days later, the BoM designated it as 07U when the system was expected to develop further.[30] The JTWC later issued a TCFA.[31] The system had fully organised into a tropical low, when the BoM had begun initiating advisories on 10 December. On the next day the JTWC upgrade to tropical storm.[32] and it was latter upgraded to Category 1 Tropical Cyclone on the Australian scale named it Ruby on 12 December, according to BoM.[33] At 18:00 UTC BoM upgrade to Category 2 system and JTWC following and upgrade to category 1-equivalent tropical cyclone,[34][35] and the next day Ruby crossed into the South Pacific basin.[36][37]

Tropical Low 03U on 22 November 2021

The Australian Bureau of Meteorology first noted the formation of a possible low-pressure system to the southwest of the island of Sumatra by 4 November.[41] This forecast was materialized when the BoM started to track a weak tropical low outside the Western Region on 9 November, while located at 400 kilometres (250 mi) to the north-northeast of the Cocos Islands.[42] It then entered the region by the next day while tracking slowly towards the island. Environmental conditions were analysed to be unfavorable for further development and as such, the BoM only forecasted a "very low" chance of the low becoming a tropical cyclone.[43] The tropical low then passed to the south of the archipelago before turning westwards and exiting the basin into the South-West Indian Ocean region by 14 November.[44][45][46]

On 22 November, a weak tropical low formed north of the Western Region, which was designated as 03U.[47] By 24 November, the tropical low had entered the region and was located 560 kilometres (350 mi) west-northwest of the Cocos Islands.[48] It meandered near the Cocos Islands, before moving westwards and exited the basin on 28 November.[49]

On 7 December, the BoM noted on a possibility of a weak tropical low developing over the northern part of the Arafura Sea.[50] The BoM designated the system as 06U.[51] By 13 December, the BoM stated that 06U was already forming.[52] The system was last noted on 15 December.[53]
