Tropical Cyclone Structure

Tropical Cyclone Structure: Overview Tropical cyclones, as areas of low pressure, are characterized by cyclonic tangential and inflowing radial winds. The cyclonic winds can extend out to over 1000 km from the center in the lower troposphere; this radial extent decays with increasing height. Tropical cyclones are warm-core features, meaning that

Cyclone - Wikipedia

In meteorology, a cyclone (/ˈsaɪ.kloʊn/) is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale).Warm-core cyclones such as tropical cyclones ...

Note that the characteristics, or isobars, dip down as the axis is approached on account of Eq. (3.15). The reason for the warm core structure of tropical cyclones is discussed later. Figure 3.5 shows an example of a calculation using the foregoing theory. The tangential wind field in Fig. 3.5a is broadly typical of that in a tropical cyclone.

Cyclonic separation - Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of ...
