Wave cyclones also develop and intensify on the east slope of the Rocky Mountains, the Gulf Coast and east coasts of North America and Asia. Figure 8.4. 1: Air collides along polar front. Especially during the spring and summer in the midlatitudes of North America, high pressure to the north pushes cold polar air southward from Canada.

Tropical cyclones (TCs) are extreme storms that form over warm tropical oceans. Along their tracks, TCs mix up cold water, which can further affect their intensity. Because of the adoption of lower-resolution ocean models, previous modeling studies on the TC response to greenhouse warming underestimated such oceanic feedbacks.

Why do tropical cyclones get more attention than extratropical cyclones? 10. Has a hurricane or cyclone ever reformed after passing over a large land mass? 3. Why exactly did the use of Greek letters as names for Hurricanes happen the first place, despite the fairly obvious and predictable impracticalities?

The term tropical cyclone frequency refers to the average number of tropical cyclones (also known as hurricanes, typhoons, etc.) which occur each year, either over the earth as a whole or in smaller regions. In this paper, the authors review the state of the science regarding what is known about tropical cyclone frequency.

Cyclones play an important role in the coupled dynamics of the Arctic climate system on a range of time scales. Modeling studies suggest that storminess will increase in Arctic summer due to enhanced land-sea thermal contrast along the Arctic coastline, in a region known as the Arctic Frontal Zone (AFZ).

Inlet cyclones separate the gas and liquid phases by inducing a spin to the fluids, with the heavier liquid phase moving to the cyclone's perimeter and the gas phase moving to the interior (Chin et al. 1999). The cyclones range from a simple empty cylinder to ones packed with turbine blades ( Figs. 1 and 2 ).

A characteristic feature of tropical cyclones is the eye, a central region of clear skies, warm temperatures, and low atmospheric pressure.Typically, atmospheric pressure at the surface of Earth is about 1,000 millibars. At the centre of a tropical cyclone, however, it is typically around 960 millibars, and in a very intense "super typhoon" of the western …

1 Introduction. Middle and high latitude cyclones have an important role in everyday weather as well as in the Earth's climate system. Cyclones play an integral part in transporting energy, momentum, and moisture from the Equator to the Poles, in part enabling life on Earth (Bader et al., 2011; Ulbrich et al., 2009; Varino et al., 2018).In the …

A decadal variation in the frequency of tropical cyclones (TCs) that reached their lifetime maximum intensity (LMI) in the South China Sea (SCS; 5°N-25°N, 107°E-121°E) from 1978 to 2020 was identified. TCs that generated and reached LMI in the SCS were named "local TCs," while those that generated in the western North Pacific (WNP) …

Bomb cyclones are explosively intensifying extratropical cyclones that develop in about a day (Sanders and Gyakum 1980) and are usually accompanied by strong winds, heavy precipitation, and high ocean waves, which can cause severe damage to life and property (Kocin et al 1995, Allen et al 2010).Most numerical studies of bomb …

The first recorded cyclone to hit was on March 8, 1878. McLeish (2017) discusses five of the most devastating cyclones to hit Queensland: TC Mahina (March 4, 1899), TC Mackay (January 21, 1918), TC Innisfail (March 10, 1918), TC Larry (March 20, 2006), and TC Yasi (February 3, 2011). Subsequent to Yasi, there have been smaller …

For a long time, researchers have tried to find a way to analyze tropical cyclone (TC) intensity in real-time. Since there is no standardized method for estimating TC intensity and the most widely used method is a manual algorithm using satellite-based cloud images, there is a bias that varies depending on the TC center and shape. In this study, …
