  2. Beaufort scale - Wikipedia

    en.wikipedia.org/wiki/Beaufort_scale

    Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.

  3. Santa Ana winds - Wikipedia

    en.wikipedia.org/wiki/Santa_Ana_winds

    These low humidities, combined with the warm, compressionally-heated air mass, plus high wind speeds, create critical fire weather conditions, and fan destructive wildfires. [4] Typically, about 10 to 25 Santa Ana wind events occur annually. [5] A Santa Ana wind can blow from one to seven days, with an average wind event lasting three days. [6]

  4. Weather map - Wikipedia

    en.wikipedia.org/wiki/Weather_map

    Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located. Use of constant pressure charts at the 700 and 500 hPa level can indicate tropical cyclone motion.

  5. Wind atlas - Wikipedia

    en.wikipedia.org/wiki/Wind_atlas

    A wind atlas contains data on the wind speed and wind direction in a region. [1] These data include maps , but also time series or frequency distributions . A climatological wind atlas covers hourly averages at a standard height (10 meters) over even longer periods (30 years) but depending on the application there are variations in averaging ...

    Charts are typically being issued every six hours (0, 6, 12, 18 UTC). The SIGWX charts only show the forecast for the specific hour, however it is common place for parameters such as the JetStream, CAT & CB to be interpreted +/- 3 hours of the chart validity time. . Prognoses are typically prepared for two ranges of heights:

  8. What caused 78 mph wind speeds in Bloomington last night? - AOL

    www.aol.com/caused-78-mph-wind-speeds-150153783.html

    Wind speeds over 75 miles per hour are classified as “hurricane force,” capable of pushing moving vehicles off the highway, overturning mobile homes and peeling off roofs. The average wind ...

  9. Winds aloft - Wikipedia

    en.wikipedia.org/wiki/Winds_aloft

    To decode this type of data group, the reverse must be accomplished. For example, when the data appears as “731960,” subtract 50 from the 73 and add 100 to the 19, and the wind would be 230° at 119 knots with a temperature of –60 °C. If the wind speed is forecast to be 200 knots or greater, the wind group is coded as 99 knots.
