Gust pressures falling below a threshold value usually taken at 2 standard deviations below the mean value are called exceedences and in a time series of a certain duration, the number of exceedences and their magnitudes are random variables.
The "worst" storm is hard to define as such events differ in extremes of wind speeds or gusts, pressure, damage or loss of human life.
The largest nuclear explosion (50 58 megatons at an altitude of about 13,000 ft) generated a 20 bar blast pressure at ground zero, which is similar to a wind gust of 3,100 miles per hour.
It is shown that in the case of wall pressures this involves calculating the joint probability of instantaneous wind direction and gust dynamic pressure.
Weather buoys, like other types of weather stations, measure parameters such as air temperature above the ocean surface, wind speed (steady and gusting), barometric pressure, and wind direction.
A number of different weather records (at the time) were set during the four days of this storm, especially in daily high temperatures, wind gusts, low barometric pressure readings, and number of tornadoes.
Select a particular aspect of the weather that you wish to track, such as average gust speed or maximum pressure.
In rural inland counties, intense gusts created so much pressure in structures that they literally exploded, as if squashed by a giant fist.
Compare the archery shot that hits the bulls-eye, but only because a gust of wind fortuitously pressured it several feet westward.
The S.S. Cristobal provided the first indications of a tropical cyclone in the region, after reporting strong gusts and low pressures north of the Panama Canal Zone during that evening.
All parameters of average and gust loads: the basic wind pressure, importance factor, territory coefficient and shape factor as well as a dynamic coefficient, are discussed here.
