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.
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]
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.
Here's a look at the wind speeds and rain totals that the storm left in its wake. Peak wind gusts for Hurricane Milton and tornadoes Al’s Family Farms Citrus, 2001 North Kings Highway on Friday ...
FOX6 News invites you to click and print off a copy of the National Weather Service wind chill chart.
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:
The highest wind gust was reported in Wilmington, Ohio, at the Wilmington Air Park in Clinton County, according to the National Weather Service. Winds reached 67 mph at 3:53 p.m. Friday.
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 ...
