They will be on and off with a mean wind
speed of 15 to 20mph coming from off the sea in a southerly direction."
The technical violability depends on the availability of mean wind
speed, which must be at least equal to 3 meter per second for its minimum utility.
Both the month's highest gust and 10-minute mean wind
speed were reported on January 26.
The strongest features can be tracked for 1-2 min, as they translate around the eyewall at ~70 m [s.sup.-1] (~157 mph, close to the mean wind
speed), while consistently producing local wind gusts in excess of 100 m [s.sup.-1] (224 mph).
The maximum 60-minute mean wind
speeds recorded at Waglan Island and Cheung Chau were 161km/h and 157km/h respectively.
Based on HKO's tropical cyclone classification, a super typhoon has a maximum 10-minute mean wind
near the center of up to 185 kilometers per hour or above.
Because RANS equation modeling can reasonably simulate mean wind
characteristics and requires less computing time than other CFD methods, it is the most widely used method in many industrial applications.
"Wellington has already seen gusts of 160 (kph) … earlier today, and Cook Strait recorded mean wind
speeds of 130 km/hr and 11-metre (36 feet) waves this morning," he said.
The Kingdom of Bahrain has been affected by fresh to strong Northwesterly winds on the 25th of May which lasted until the end of the month and reached near gale to gale on the 31st of May especially in the Southern areas where the mean wind
speed 39 knots and gusts reached 46 knots and that was due to the seasonal low pressure developed over central and southern parts of Pakistan which extended in to the Arabian Gulf leading to shamal winds which are known locally as (Al-Barreh) Thick dust haze was reported on the 9th of May where visibility dropped to 800 meters at Bahrain International Airport.
Headwind approaches from the north experience the most severe wind shear effects, with mean wind
speed changes of up to 20kts occurring over a short distance along the approach trajectory.
It is found that when wind speed is greater than 11 m/s, the noise-to-signal ratio (i.e., the RMS of wind pressure divided by the mean wind
pressure) is kept below 10% (see Figure 5(a)).
The effects of the mean wind
velocity, vehicle speed, and the roughness level on the dynamic reliability are also studied.
