For example, each severe tropical cyclone (i.e. Category 4–5 on the Saffir-Simpson scale) crossing northeast Australia's tropical coastline since the last significant change in sea levels (about 5,000 years ago) has 'emplaced' such ridges within the coastal landscape forming, in some places, series of ridges and a geomorphological record of ...

Where V srm is the max wind speed corrected for storm speed, phi is the latitude, and S is the size parameter. [5] S is more specifically defined as the ratio of tangential wind at a radius of 500 kilometres (310 mi) to its value under a Rankine vortex model.
Tropical cyclone naming – once a tropical cyclone reaches winds of 34 kt (39 mph), a name would be given to that specific cyclone. Names are usually given by their respective RSMCs when the cyclone reaches tropical storm status. History of tropical cyclone naming – history of tropical cyclone naming from the late 18th century onward.
The total is likely higher because satellite monitoring technology was not available until the 1960s and cyclones that could have been a Category 5 storm may have remained undetected.
Climate change has likely been driving the observed trend of rapid intensification of tropical cyclones in the Atlantic basin, with the proportion of storms undergoing intensification nearly doubling over the years 1982 to 2009. [36] [37] Rapidly intensifying cyclones are hard to forecast and pose additional risk to coastal communities. [38]
