Australian region tropical cyclone seasons
2007–08, 2008–09, 2009–10, 2010–11, 2011–12

The 2009-10 Australian region cyclone season is an event in the ongoing cycle of tropical cyclone formation. It officially started on 1 November 2009, and will end on 30 April 2010. The regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on 1 July 2009 and will end on 30 June 2010.[1]

The scope of the Australian region is limited to all areas south of the equator, east of 90°E and west of 160°E. This area includes Australia, Papua New Guinea, western parts of the Solomon Islands, East Timor and southern parts of Indonesia. [1]

Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; TCWC Jakarta in Indonesia; and TCWC Port Moresby in Papua New Guinea.[1] The Joint Typhoon Warning Centre issues unofficial warnings for the region, designating tropical depressions with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E.

TCWC Jakarta

[edit]

TCWC Jakarta monitor Tropical Cyclones from the Equator to 10S and from 90E to 125E. Should a Tropical Depression reach Tropical Cyclone strength within Jakartas Area of Responsibilty then it will be assigned a name from the following list. [4] The first five names of the list are shown below. Names that have not yet been assigned are shown in gray; bold names are currently active.

Bureau of Meteorology

[edit]

Since the start of the 2008–09 Tropical Cyclone year, there has only been one list that the Bureau of Meteorology have assigned names to Tropical Cyclones from.[5] However the Bureau of Meteorology will still operate the various TCWCs in Perth, Darwin & Brisbane. They monitor all tropical cyclones that form between 90°E and 160°E, issuing special advisories when a cyclone forms in either TCWC Jakarta's or Port Moresby's area of responsibilty.

TCWC Port Morseby

[edit]

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. Tropical cyclone formation in this area is rare, with no cyclones developing in it since 2007.[6] As names are assigned in a random order the whole list is shown below. Names that have not yet been assigned are shown in gray; bold names are currently active.
