  2. Significant wave height - Wikipedia

    en.wikipedia.org/wiki/Significant_wave_height

    Significant wave height H m0, defined in the frequency domain, is used both for measured and forecasted wave variance spectra.Most easily, it is defined in terms of the variance m 0 or standard deviation σ η of the surface elevation: [6] = =, where m 0, the zeroth-moment of the variance spectrum, is obtained by integration of the variance spectrum.

  3. Barometric formula - Wikipedia

    en.wikipedia.org/wiki/Barometric_formula

    Pressure as a function of the height above the sea level. There are two equations for computing pressure as a function of height. The first equation is applicable to the atmospheric layers in which the temperature is assumed to vary with altitude at a non null lapse rate of : = [,, ()] ′, The second equation is applicable to the atmospheric layers in which the temperature is assumed not to ...

  4. Wave height - Wikipedia

    en.wikipedia.org/wiki/Wave_height

    Depending on context, wave height may be defined in different ways: For a sine wave, the wave height H is twice the amplitude (i.e., the peak-to-peak amplitude): [1] =.; For a periodic wave, it is simply the difference between the maximum and minimum of the surface elevation z = η(x – c p t): [1] = {()} {()}, with c p the phase speed (or propagation speed) of the wave.

  5. Scale height - Wikipedia

    en.wikipedia.org/wiki/Scale_height

    T = mean atmospheric temperature in kelvins = 250 K [4] for Earth m = mean mass of a molecule M = mean molar mass of atmospheric particles = 0.029 kg/mol for Earth g = acceleration due to gravity at the current location. The pressure (force per unit area) at a given altitude is a result of the weight of the overlying atmosphere.

  6. Full width at half maximum - Wikipedia

    en.wikipedia.org/wiki/Full_width_at_half_maximum

    Full width at half maximum. In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value.

    Typically, other TikTok users create a clip challenging him to guess their height — then, using videos, Instagram photos or whatever else he can find, he gets to work. Meet the TikToker who ...

  8. Height above mean sea level - Wikipedia

    en.wikipedia.org/wiki/Height_above_mean_sea_level

    Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.
