How Do Outer Spiral Rainbands Affect Tropical Cyclone
Abstract A long-standing issue on how outer spiral rainbands affect the structure and intensity of tropical cyclones is studied through a series of numerical experiments using the cloud-resolving tropical cyclone model TCM4. Because diabatic heating due to phase changes is the main driving force of outer spiral rainbands, their …
Effect of Inlet Air Volumetric Flow Rate on the Performance …
It is very important to improve the cyclone separator separation efficiency for fine particles. On the basis of the Reynolds stress model (RSM), a new two-stage cyclone separation device is modeled and the model is simulated under six kinds of air volumetric flow rate conditions. The two-stage cyclone separator was then tested in the laboratory and the …
A Shortening of the Life Cycle of Major Tropical Cyclones
1 Introduction. A fundamental property of tropical cyclones (TCs) is the intensity life cycle, measured conventionally by the near-surface maximum wind speed (V m).A TC intensity life cycle can be decomposed into four stages: genesis, intensification, maturity, and weakening/transition (Dunn & Miller, 1960; Riehl, 1954; Simpson & Riehl, …
Here's why hurricanes spin counterclockwise in the North
When these winds collide, they will swirl clockwise in the south, and counterclockwise in the north. A variety of factors influence how hurricanes form. First they require warm water and warm ...
16: Tropical Cyclones
Low-altitude winds also rotate cyclonically (counterclockwise in the N. Hemisphere) around these storms and spiral in towards their centers. Tropical cyclones are called …
13.1: Cyclone Characteristics
The central pressure continues to rise and winds weaken. The tightly wound spiral of clouds begins to dissipate into scattered clouds, and precipitation diminishes. But meanwhile, along the stationary front to the east, a new cyclone might form if the jet stream is favorable (not shown in the figures). In this way, cyclones are born, evolve ...

Hurricanes, Cyclones, and Typhoons Explained
Tropical Cyclone Amanda. The names of the powerful storms that form in the waters of the Atlantic and Pacific—whether hurricane, cyclone, or typhoon—depends on where they form. Tropical Cyclone Amanda was a category 4 on the Saffir-Simpson scale imaged by NASA's Aqua satellite. Centuries ago European explorers learned the …

Hurricanes, Typhoons, and Cyclones | Smithsonian Ocean
In the South Pacific Ocean, for instance, it's a hurricane if it occurs east of 160 degrees E and a severe tropical cyclone if it occurs west of 160 degrees E. To avoid confusion, most scientists use "tropical cyclone" as a general term (one which also includes tropical depressions and tropical storms) no matter where the storm occurs.
Tropical cyclone spiral band extraction and center locating …
Tropical cyclone (TC) center locating is crucial because it lays the foundation for TC forecasting. Locating TC centers, usually by manual means, continues to present many difficulties. Not least is the problem of inconsistency between TC center locations forecast by different agencies. In this paper, an objective TC center locating scheme is …
Spiral band model for locating Tropical Cyclone centers
It can assist forecasters in locating TC centers by providing objective information. In order to locate Tropical Cyclones automatically, a spiral band model is designed. The information of spiral pattern of the spiral rain cloud bands can be utilized better than existing curvilinear models. The locating approach converts the locating …

Spiral gravity waves radiating from tropical cyclones
Thunderstorms in the cores of tropical cyclones generate waves that radiate outward in expanding spiral patterns. These waves can be detected in satellite images, from aircraft, and even surface …
Generation of Moving Spiral Bands in Tropical Cyclones
Abstract A theory based on the shallow water equation is developed to explain the generation of moving spiral-banded structures in tropical cyclones. The theory proposes that fluctuation of the vorticity distribution in the compact core region can act as a source, generating gravity waves that produce the banded structures. This mechanism is usually …
Spiral Flow Type Cyclone Gas Liquid Separator
A 'spiral flow type' cyclone gas liquid separator is a filtering device used for separating solid particles or liquid droplets from gas flow. These devices are typically used in two phase separators at the gas outlet, to enhance the overall separation efficiency of the equipment. The structure of spiral flow internal devices do not need the gas ...
