  2. Wind gradient - Wikipedia

    en.wikipedia.org/wiki/Wind_gradient

    According to one source, [39] the wind gradient is not significant for sailboats when the wind is over 6 knots (because a wind speed of 10 knots at the surface corresponds to 15 knots at 300 meters, so the change in speed is negligible over the height of a sailboat's mast). According to the same source, the wind increases steadily with height ...

    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 ...

    This explains why an area like the Pinnacles National Park can have high temperatures of 38 °C (100 °F) during a summer day, and then have lows of 5–10 °C (41–50 °F). At the same time, Washington D.C. , which is much more humid, has temperature variations of only 8 °C (14 °F); [ 1 ] [ dead link ‍ ] urban Hong Kong has a diurnal ...

    Whether you’re on a weight loss journey or not, weight fluctuations are normal. But that doesn’t mean it’s any less confusing when the scale says you’re up a few pounds from the day before.

  7. Tropopause - Wikipedia

    en.wikipedia.org/wiki/Tropopause

    The tropopause is defined as the lowest level at which the lapse rate decreases to 2°C/km or less, provided that the average lapse-rate, between that level and all other higher levels within 2.0 km does not exceed 2°C/km. [1] The tropopause is a first-order discontinuity surface, in which temperature as a function of height varies ...

  8. Atmospheric temperature - Wikipedia

    Following the tropopause is the stratosphere. This layer extends from the tropopause to the stratopause, which is located at an altitude of about 50 km (31 mi). Temperatures remain constant with height from the tropopause to an altitude of 20 km (12 mi), after which they start to increase with height.
