In general, a condition of the atmosphere characterized by a central area of pressure much lower than that of surrounding areas, and a system of winds blowing inward and around (clockwise in the southern hemisphere and counter-clockwise in the northern); -- called also a {low-area storm}.

Cyclone Debbie (n.) 氣旋黛比;強烈熱帶氣旋黛比 Severe Tropical Cyclone Debbie in 2017 was the strongest tropical cyclone in the Australian region since Cyclone Quang in 2015, and was branded the most dangerous cyclone to impact Queensland since Cyclone Yasi in 2011. Forming as a tropical low on 23 March, the low gradually intensified to a named tropical cyclone on 26 March. After steadily strengthening offshore to a Category 4 system, Debbie eventually made landfall near Airlie Beach, just north of Proserpine, at around 12:40 AEST on 28 March.[1] Afterwards, Debbie rapidly weakened into a tropical low by late 28 March, but continued to travel south, causing significant damage and flooding in the populous areas of South East Queensland and Northern Rivers.[1] In total, the storm caused A$2.4 billion (US$1.85 billion) in damage and fourteen deaths across Australia, primarily as a result of extreme flooding. This makes Debbie the deadliest cyclone to hit Australia since Cyclone Tracy in 1974.[2]

Extratropical cyclone (n.) 溫帶氣旋,亦稱為鋒面氣旋或中緯度氣旋 Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone.[1]
