  2. Dvorak technique - Wikipedia

    en.wikipedia.org/wiki/Dvorak_technique

    Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...

  3. Maximum sustained wind - Wikipedia

    en.wikipedia.org/wiki/Maximum_sustained_wind

    In most tropical cyclone basins, use of the satellite-based Dvorak technique is the primary method used to estimate a tropical cyclone's maximum sustained winds. [5] The extent of spiral banding and difference in temperature between the eye and eyewall is used within the technique to assign a maximum sustained wind and pressure. [6]

  4. Cyclonic separation - Wikipedia

    en.wikipedia.org/wiki/Cyclonic_separation

    As the cyclone is essentially a two phase particle-fluid system, fluid mechanics and particle transport equations can be used to describe the behaviour of a cyclone. The air in a cyclone is initially introduced tangentially into the cyclone with an inlet velocity . Assuming that the particle is spherical, a simple analysis to calculate critical ...

  5. Radius of maximum wind - Wikipedia

    en.wikipedia.org/wiki/Radius_of_maximum_wind

    The radius of maximum wind of a tropical cyclone lies just within the eyewall of an intense tropical cyclone, such as Hurricane Isabel from 2003. The radius of maximum wind (RMW) is the distance between the center of a cyclone and its band of strongest winds. It is a parameter in atmospheric dynamics and tropical cyclone forecasting. [1]

  6. Maximum potential intensity - Wikipedia

    en.wikipedia.org/wiki/Maximum_potential_intensity

    A tropical cyclone may be viewed as a heat engine that converts input heat energy from the surface into mechanical energy that can be used to do mechanical work against surface friction. At equilibrium, the rate of net energy production in the system must equal the rate of energy loss due to frictional dissipation at the surface, i.e.

  7. Synoptic scale meteorology - Wikipedia

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    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).

  8. Dust collector - Wikipedia

    en.wikipedia.org/wiki/Dust_collector

    Two rooftop dust collectors in Pristina, Kosovo. A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system ...

  9. Balanced flow - Wikipedia

    en.wikipedia.org/wiki/Balanced_flow

    The chart shows how the different speeds change in the conditions chosen above and with increasing radius of curvature. The geostrophic speed (pink line) does not depend on curvature at all, and it appears as a horizontal line. However, the cyclonic and anticyclonic gradient speeds approach it as the radius of curvature becomes indefinitely ...
