The 2004-05 Australian region cyclone season was an event in the ongoing cycle of tropical cyclone formation. It began on November 1, 2004 and ended on April 30, 2005. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from July 1, 2004 to June 30, 2005.

Tropical cyclones in this area are monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea.[1]

[edit] Storms

[edit] Tropical Cyclone Phoebe

Category 1 tropical cyclone (BoM)
Tropical storm (SSHS)
{{{Image}}} Phoebe 2004 track.png
Duration August 30—September 5
Intensity 85 km/h (50 mph) (10-min), 990 hPa (mbar)

A tropical disturbance developed in the east of the region monitored by Réunion on August 30, from an active monsoon band that coincided with a burst in the Madden-Julian oscillation. The system moved southeast and entered the Perth Tropical Cyclone Warning Centre's area of responsibility on September 1.

The system was upgraded to Tropical Cyclone Phoebe early on September 2 when it was about 800 km west-northwest of the Cocos Islands. Phoebe quickly reached its peak strength that day, with winds of 85 km/h, as it continued to move to the southeast. The cyclone weakened as it moved over cooler water and dissipated about 550 km from the Cocos Islands. Phoebe posed no threat to any land.[1]

[edit] Tropical Low (05S)

Tropical low (BoM)
Tropical storm (SSHS)
{{{Image}}}
Duration December 3—December 5
Intensity 55 km/h (35 mph) (10-min), 998 hPa (mbar)

A tropical low developed in the Perth AOR on December 2 near the coast of Java. According to Perth, the storm had a maximum sustained winds of 30 knots (56 km/h), while the JTWC assigned the storm peak sustained winds of 35 knots (65 km/h) and classifying it as a tropical storm.

[edit] Tropical Cyclone Raymond

Category 1 tropical cyclone (BoM)
Tropical storm (SSHS)
TC Raymond 02 jan 2005 0210Z.jpg Raymond 2004 track.png
Duration January 1—January 2
Intensity 85 km/h (50 mph) (10-min), 985 hPa (mbar)

A tropical low developed from a area of convection of the Western Australia coast on December 30. The system drifted southeast, then turned to the northeast over the following days without significant development. The low began to drift to the southeast again on January 1 and the convection began to increase, with it becoming Tropical Cyclone Raymond on January 2, when it was 460 km north-northeast of Broome.

The cyclone peaked with 85 km/h winds as it moved east, and made landfall as a Category 1 cyclone just west of Kalumburu the same day. The cyclone weakened over land, and the remnant low continued east over the Northern Territory, entering the Gulf of Carpentaria on January 5. The low reversed direction and dissipated by January 10.[2] Cyclone Raymond caused no damage, but brought the first heavy rain of the reason to northern Kimberley.[3]

[edit] Severe Tropical Cyclone Kerry

Category 3 severe tropical cyclone (BoM)
Category 2 tropical cyclone (SSHS)
Tropical Cyclone Kerry 2005.jpg Kerry 2005 track.png
Duration January 8—January 18
Intensity 150 km/h (90 mph) (10-min), 955 hPa (mbar)

Tropical Cyclone Kerry developed from Tropical Depression 5 °F (−15 °C) on January 5 in Fiji's AOR, 315 nautical miles (583 km) northeast of Port Vila, Vanuatu. Kerry moved to the southwest with 40-knot (74 km/h) winds as it moved over Vanuatu. Once past the island, Kerry moved on a west-southwest course and it began to intensify after turning to the west. The storm reached a peak intensity of 85 knots (157 km/h) before turning towards the south-southeast. The storm began to weaken under vertical shear and was downgraded to a depression on January 13.

[edit] Tropical Cyclone Sally

Category 2 tropical cyclone (BoM)
Tropical storm (SSHS)
{{{Image}}} Sally 2005 track.png
Duration January 7—January 9
Intensity 95 km/h (60 mph) (10-min), 985 hPa (mbar)

A area of convection began to develop 930 km west-southwest of Jakarta on January 6, becoming a tropical low the next day. The low intensified as it drifted south and was named Sally 370 km east-southeast of the Cocos Islands on January 8. Cyclone Sally slowly moved to the southwest, under the influence of a mid-level ridge to the southeast, reaching its peak with 95 km/h winds on January 9. The storm then rapidly weakened as a result of the presence of dry air and increased wind shear, before dissipating early on January 10 460 km west-southwest of the Cocos Islands. Cyclone Sally had no effects on land.[4]

[edit] Tropical Low (10S)

Tropical low (BoM)
Tropical storm (SSHS)

{{{Image}}} Tim 2005 track.png
Duration January 23—January 25
Intensity 85 km/h (50 mph) (10-min), 990 hPa (mbar)

A tropical low located about 930 km north of Learmonth, Western Australia began to develop a deeper convection on January 23, despite being beneath the subtropical ridge. The low became Tropical Cyclone Tim the next day, when it was 700 km southeast of Christmas Island. Tim moved slowly to the southwest, as a result of steering from an anticyclone to the southeast. The storm reached briefly reached a peak with wind of 85 km/h late on January 23. Tim lost tropical cyclone status on January 25 to 470 km south-west of Christmas Island and the remnant continued west before dissipating. There was no damage as a result of Cyclone Tim.[6]

[edit] Severe Tropical Cyclone Harvey

Category 3 severe tropical cyclone (BoM)
Tropical storm (SSHS)
Cyclone Harvey 2005.jpg Harvey Pacific 2005 track.png
Duration February 5—February 7
Intensity 130 km/h (80 mph) (10-min), 967 hPa (mbar)

The Bureau of Meteorology began monitoring a tropical low off Groote Eylandt in the Gulf of Carpentaria on February 3, 2005. The low intensified and was named Harvey three days later. The storm made landfall near the Queensland/Northern Territory border on February 7 as a Category 3 (Australian scale) system. Minor structural damage was reported along the Robinson River and Mornington Island was battered by high winds and heavy rain, however no casualties were reported.

[edit] Tropical Cyclone Vivienne

Intensity 65 km/h (40 mph) (10-min), 990 hPa (mbar)

A tropical low developed within the monsoon trough about 550 km northwest of Broome, Western Australia on February 4. The low gradually became more organized as it drifted slowly to the southwest, but did not intensify until it became Tropical Cyclone Vivienne on February 8. The cyclone peaked with 65 km/h winds and remained near stationary, before dissipating later that day.[7] Oil and gas production in the Timor Sea was disrupted by Cyclone Vivienne.[8]

[edit] Severe Tropical Cyclone Ingrid

Category 5 severe tropical cyclone (BoM)
Category 4 tropical cyclone (SSHS)
Cyclone Ingrid 2005.jpg Ingrid 2005 track.png
Duration March 5—March 17
Intensity 230 km/h (145 mph) (10-min), 924 hPa (mbar)
Main article: Cyclone Ingrid

Cyclone Ingrid was an intense cyclone, impacting Queensland, Northern Territory and Western Australia as a Category 4 or 5 cyclone.[2]

[edit] Severe Tropical Cyclone Willy

Category 3 severe tropical cyclone (BoM)
Category 2 tropical cyclone (SSHS)
{{{Image}}} Willy 2005 track.png
Duration March 9—March 14
Intensity 140 km/h (85 mph) (10-min), 960 hPa (mbar)

A tropical low began to develop on March 8, 830 km north of Port Hedland, Western Australia. The low did not move as it developed and became Tropical Cyclone Willy in the same area. Willy moved slowly west-southwest, roughly parallel to the Australian coast, strengthening steadily in the favourable environment. It reached its peak with 140 km/h winds on March 11 when it was 550 km northwest of Onslow.

Cyclone Willy then turned to the southwest and maintained its strength for a day before it began to weaken. The storm turned to the west and weakened into a remnant low on March 14. The remnant continued to drift west away from Australia before dissipating a few days later.[9] Oil production in the Timor Sea was disrupted by Cyclone Willy, but there were no effects on land.[10]

[edit] Severe Tropical Cyclone Adeline-Juliet

Category 3 severe tropical cyclone (BoM)
Category 2 tropical cyclone (SSHS)
TC Adeline-Juliet 06 apr 2005 0400Z.jpg Adeline-Juliet 2005 track.png
Duration April 3—April 5
Intensity 140 km/h (85 mph) (10-min), 960 hPa (mbar)

A tropical low formed roughly 710 km east-northeast of the Cocos Islands on April 1. The system developed moved southwest towards the Cocos Islands and became Tropical Cyclone Juliet on April 3, when it was 45 km east of the islands. The system steadily intensified as it moved west, becoming a severe tropical cyclone on April 4. Cyclone Adeline crossed into Réunion's area of responsibility on April 5, by which time it had 140 km/h winds.

Météo-France renamed the storm Juliet when they assumed responsibility for the cyclone, as it passed west of 90°E.[11] Cyclone Adeline triggered gale warnings on the Cocos Islands, where 160 mm of rain fell in one day. The storm caused minor damage and uprooted trees on the islands.[12]

[edit] Papua New Guinea Tropical Storm

Tropical cyclone (Brisbane)

Duration April 13—April 15
Intensity Winds unknown, 990 hPa (mbar)

This small cyclone brought gale-force winds in Port Moresby and surrounding areas in Papua New Guinea in April.[3]

[edit] Storm names

Tropical cyclones are assigned names by the Australian Bureau of Meteorology or Papua New Guinea.

Tropical cyclones are named if they are non-frontal low pressure systems of synoptic scale developing over warm waters, or Dvorak intensity analysis indicate the presence of gale force or stronger winds near the centre. Therefore, a tropical system with gales in one or more quadrants, but not near the centre, are not named.[4]

All names assigned in the Australian region are used sequentially, unlike lists used annually by the National Hurricane Centre in the Atlantic Ocean and east Pacific Ocean. Only the names used during this cyclone season are listed below. The complete list of names for each basin are found in the World Meteorological Organization's official list.

[edit] Southeast Indian Ocean

Tropical cyclones that develop east of 90°E, south of the Equator, and west of 125°E are assigned names by the Tropical Cyclone Warning Centre in Perth, Western Australia.[1]

  • Phoebe
  • Raymond
  • Sally
  • Tim
  • Vivienne
  • Willy
  • Adeline

[edit] Arafura Sea and Western Gulf of Carpentaria

Tropical cyclones that develop south of the Equator between 125°E and 141°E are assigned names by the Tropical Cyclone Warning Centre in Darwin, Northern Territory.[1]

No tropical cyclone names were used in the 2004-05 season.

[edit] Coral Sea and Eastern Gulf of Carpentaria

Tropical cyclones that develop south of 10°S between 141°E and 160°E are assigned names by the Tropical Cyclone Warning Centre in Brisbane, Queensland.[1]

  • Harvey
  • Ingrid

Note also that Cyclone Kerry from the South Pacific region also affected the area monitored by Brisbane's Tropical Cyclone Warning Centre.

[edit] Solomon Sea and Gulf of Papua

Tropical cyclones that develop north of 10°S between 141°E and 160°E are assigned names by the Tropical Cyclone Warning Centre in Port Moresby, Papua New Guinea.[1]

No tropical cyclone names were used in the 2004-05 season.
