The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
Category 4 hurricanes have maximum sustained winds of 113–136 knots (130–156 mph, 209–251 km/h). [1] " Sustained winds" refers to the average wind speed observed over one minute at a height of 10 meters (33 ft) above ground.
Here are some of the highest wind speeds recorded early Tuesday across Los Angeles and Ventura counties, according to the National Weather Service office in L.A. Magic Mountain Truck Trail – 72 ...
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.
The wind speeds may have been accelerated by climate change. Citing a recent study, meteorologist Jeff Beradelli said that for every 1°C increase in air temperatures, there could be a 2 per cent ...
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 ...
A very strong typhoon has wind speeds between 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a violent typhoon has wind speeds of 105 kn (54 m/s; 121 mph; 194 km/h) or greater. [8] The HKO, SMG and the CMA also divide the typhoon category into three categories, with both assigning a maximum wind speed of 80 kn (41 m/s; 92 mph ...
By 00:00 UTC on September 24, the depression's wind speed had increased to 40 mph (64 km/h), at which time it became Tropical Storm Ian. Moderate-to-strong vertical wind shear hindered development of Ian until late the following day; it began rapidly intensifying at 18:00 UTC September 25. Ian became a hurricane 12 hours later and a major ...
