usually trails a thick layer of low stratus clouds bringing episodic drizzle, banks up against the Great Dividing Range, thus resulting in the transmission of the cool maritime air near the southeastern part of the ranges and the blocking of the airflow on the mountains' west side. The Buster progresses into a strongly stable boundary layer with warm, prefrontal landmass air that is between 100 and 200 metres deep transporting over the cooler waters. In some occasions, a cold front in the Southern Ocean may interact with the Great Dividing Range and develop into a Southerly Buster. It is worth noting that some Southerly Busters are not southern ocean fronts, as they have developed on the pre-frontal trough south of Australia or have possibly originated on the southern NSW coast in affiliation with a shallow mesoscale low development. As the Southerly Buster advances to the north, its force would decrease, though in rare occasions it can fortify north of the Hunter Valley due to upslope motion on the valley's north, which allows the flow to produce anticyclonic vorticity akin to the original obstruction and arrangement of the Southerly Buster in Victoria. However, the southerly buster does not always create precipitation, aside from light drizzle and light rain, which tend to occur a day after the southerly buster's arrival as its effects may still persist for 24 hours, in addition to creating a weather pattern similar to that of a June Gloom experienced in Southern California. It is proposed that the southerly buster is basically a coastal gravity current that is held against the mountains by the Coriolis force and in transverse geostrophic balance, and is generated when a cold front is obstructed, experiencing anticyclonic distortion near the Great Dividing Range, spreading northward as a coastal trapped orographic jet. The southerly buster is caused by its interaction with the Great Dividing Range, as the cool air becomes trapped against the ranges, oftentimes in the Gippsland area of Victoria, where the mountains create a channelling effect as the southerly winds move across the New South Wales coast. When the inland portion of the cold front is held against the mountains, the part over the sea proceeds to move along the shore, twisting the front into an 'S' shape. This activity continues on the southern New South Wales coast, while areas leading the front are still experiencing hot northwesterly winds. Other phenomena that
