  2. Pressure-wind relationship calculations for tropical cyclones

    en.wikipedia.org/wiki/Pressure-wind_relationship...

    The interchangeability of pressure and wind allows for the two to be used to give equivalencies for the public. [3] Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [8] Some storms may have particularly high or low pressures that do not match with their wind speed.

  3. Pressuremeter test - Wikipedia

    en.wikipedia.org/wiki/Pressuremeter_Test

    A pressuremeter is a meter constructed to measure the “at-rest horizontal earth pressure”. The pressuremeter has two major components. [1] The first component is a read-out unit that remains above ground. The second component of the pressure meter is a probe that is inserted into the borehole (ground) to read the pressure.

  4. Water pinch analysis - Wikipedia

    en.wikipedia.org/wiki/Water_pinch_analysis

    The source and sink composite curves is a graphical tool for setting water recovery targets as well as for design of water recovery networks. [5] A 2018 study found by water pinch and water footprint analysis that for bricks with typical materials of clay and shale, the water consumption footprint was 2.02 L of water per brick. [6]

  5. Potential flow - Wikipedia

    en.wikipedia.org/wiki/Potential_flow

    The velocity potential of a point source or sink of strength (> for source and < for sink) in spherical polar coordinates is given by ϕ = − Q 4 π r {\displaystyle \phi =-{\frac {Q}{4\pi r}}} where Q {\displaystyle Q} in fact is the volume flux across a closed surface enclosing the source or sink.

  6. Trough (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Trough_(meteorology)

    A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at ...

  8. Penman equation - Wikipedia

    en.wikipedia.org/wiki/Penman_equation

    The Penman equation describes evaporation (E) from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature, wind speed, air pressure, and solar radiation to predict E. Simpler Hydrometeorological equations continue to be used where obtaining such data is impractical, to give comparable results within specific contexts, e.g. humid vs ...

  9. Wind setup - Wikipedia

    en.wikipedia.org/wiki/Wind_setup

    Wind setup, also known as wind effect or storm effect, refers to the rise in water level in seas, lakes, or other large bodies of water caused by winds pushing the water in a specific direction. As the wind moves across the water’s surface, it applies shear stress to the water, generating a wind-driven current.
