In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ).
The HSI is a 0 to 50 point scale, allotting up to 25 points for a tropical cyclone's intensity and up to 25 points for wind field size. [34] Points are awarded on a sliding scale, with the majority of points reserved for hurricane force and greater wind fields. [34] A paper describing the scale was published in 2008. [35]
A polar low is a small-scale, short-lived atmospheric low-pressure system (depression) that is found over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres. Polar lows were first identified on the meteorological satellite imagery that became available in the 1960s, which revealed many small-scale ...
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
Category 3 is known to be the third-highest classification on the Australian tropical cyclone intensity scale which is used to classify tropical cyclones ...
The most recognisable of these from name alone is arguably the tropical variety, though tropical cylones are just one type of cyclonic weather system of many. Cyclones in meteorology can vary in scale from small mesocyclones through to large extratropical cyclones, to often smaller but far more powerful tropical cyclones.
However, in 2019 eight cyclonic storms formed, becoming the record highest number of tropical cyclones in the sub-basin, which was tied with the 1902 season. [ 24 ] [ 25 ] Research has found that in recent decades the sea surface temperatures has risen up by 1.2–1.4 °C (2.2–2.5 °F) in the Arabian Sea. [ 25 ]
Saffir-Simpson Hurricane Scale – a scale widely used by the National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center to determine a storm's strength using maximum sustained winds. Accumulated cyclone energy – a metric used by several agencies to measure the longetivity of a tropical cyclone.
