強烈熱帶氣旋 was a very powerful tropical cyclone that struck Australia's Northern Territory and the Kimberley region of Western Australia in March 2018. It was the strongest tropical cyclone of the 2017–18 Australian region cyclone season, as well as the strongest tropical cyclone in the Australian region basin since George in 2007. It was also considered the worst cyclone to hit Darwin since Tracy in 1974.[2]

On 15 March 2018, a tropical low formed in the western Arafura Sea.[3] Drifting east-southeastwards north of the Tiwi Islands, the tropical low consolidated into a Category 1 tropical cyclone on the Australian scale early on 16 March, and was accordingly given the name Marcus.[4] In a generally favourable environment for intensification, Cyclone Marcus reached Category 2 status in the hours before it crossed the Northern Territory coastline, on 17 March.[5]

Marcus intensified markedly upon moving away from the coast. Soon, the storm started to rapidly intensify and by 21 March, Marcus reached Category 5 intensity.[6] However, after doing so, the storm began to rapidly weaken due to a combination of an eyewall replacement cycle, stronger wind shear, and cooler waters.[7] Marcus continued to rapidly weaken as it moved southward. The system soon transitioned into an extratropical cyclone on March 25. On March 27, the extratropical remnant of Marcus dissipated off the southwest coast of Australia.[來源請求]

Preparation and impact[编辑]

Before the storm, on 15 March, the Australian Bureau of Meteorology issued cyclone warnings for Darwin, the Tiwi Islands and parts of the northwest Top End.[8] Major events and flights in and out of Darwin were cancelled.[9] Approximately 26,000 homes were affected by electricity outages as a result of the destructive winds, even in areas as far south as Batchelor and Adelaide River.[10] Thousands of trees were destroyed across the Greater Darwin region including many African mahoganies planted after Cyclone Tracy for their fast growing and expansive shade qualities.[11][12]

Public schools and non-essential public service agencies were closed while the clean-up efforts continued and tree trunks removed from roads.[10] Cyclone Marcus was the most destructive storm to hit Darwin since Cyclone Tracy caused devastation on Christmas Eve of 1974.[13]

The cleanup response was coordinated by the Northern Territory Emergency Services and included soldiers from the 5th Battalion and the 1st Combat Engineer Regiment from the Australian Army. The US Marine Rotational Force – Darwin (MRF-D) also contributed to the clean up effort.[14]

Retirement[编辑]

Due to the damage caused by the cyclone in Darwin and its subsequent intensification, the name Marcus was retired.[15]
