  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. Betz's law - Wikipedia

    en.wikipedia.org/wiki/Betz's_law

    In high wind speed, where the turbine is operating at its rated power, the turbine rotates (pitches) its blades to lower C P to protect itself from damage. The power in the wind increases by a factor of 8 from 12.5 to 25 m/s, so C P must fall accordingly, getting as low as 0.06 for winds of 25 m/s.

  4. Pipe network analysis - Wikipedia

    en.wikipedia.org/wiki/Pipe_network_analysis

    To direct water to many users, municipal water supplies often route it through a water supply network. A major part of this network will consist of interconnected pipes. This network creates a special class of problems in hydraulic design, with solution methods typically referred to as pipe network analysis. Water utilities generally make use ...

  5. 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 ...

  6. Wind energy software - Wikipedia

    en.wikipedia.org/wiki/Wind_energy_software

    Wind farm monitoring software is a software that allows people to see if the wind turbines are running well or are going to become broken. Other functions of monitoring software is reporting, analysis of measurement data (power curve) and tools for monitoring of environmental constraints (bat control, etc.).

  7. Antarctic Automatic Weather Stations Project - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Automatic...

    The Antarctic Automatic Weather Station (AWS) Project is an Antarctic research program at the Space Science and Engineering Center at the University of Wisconsin–Madison that is funded by the Office of Polar Programs at the National Science Foundation (NSF). The AWS project was started in 1980 by UW-Madison atmospheric sciences Professor ...

  8. Low-pressure area - Wikipedia

    en.wikipedia.org/wiki/Low-pressure_area

    [50] [52] Friction with land slows down the wind flowing into low-pressure systems and causes wind to flow more inward, or flowing more ageostrophically, toward their centers. [48] Tornadoes are often too small, and of too short duration, to be influenced by the Coriolis force, but may be so-influenced when arising from a low-pressure system ...

  9. 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 ...
