Strong winds can endanger people and material. The potential of damage depends not only on the maximum wind speed, but also on the duration and thus the transported energy of the wind. For this reason (and because of measurement system differences), meteorologists use the size of the gust instead of the maximum speed peak. Read in this article, what a gust of wind can do, how it is defined and how you can now measure gusts reliably and without additional accessories with the Lufft Ventus and Lufft V200A.<\/p>

Haiyan, Katrina, Kyrill, Nargis \u2013 even years later these names of storms are echoing in our minds and in the affected areas sometimes even decades. Hurricanes can cause devastating damage and claim thousands of lives. Whether they are called typhoon, hurricane, or cyclone is only a regional term.<\/p>

In addition to air pressure and diameter, an important parameter used by meteorologists to describe hurricanes is wind speed. The storms mentioned all made the news with figures of over 200 kilometres per hour, Typhoon Haiyan even reached 315 km\/h. Here is an overview of the storms, their dimensions and effects.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Different measuring methods<\/h3>

Now the measurement of wind speeds is a science of its own. The speed data refer to values averaged over one minute. Consequently, the winds reached even higher speeds at their peak. However, for several reasons it does not make sense to show the maximum value, quasi the strongest gust of wind.<\/p>

On the one hand, very short wind peaks carry little energy and thus a low damage potential. The longer a wind blows, the greater the energy it transfers to anything that gets in its way. On the other hand, different measuring methods react to a gust of wind with different strengths or at different speeds. Analogue cup anemometers (anemometers are wind gauges), for example, require a certain start-up time due to their mechanical resistance. They therefore react more inertly and cannot detect very short gusts of wind comprehensively. Ultrasonic sensors are capable of this and function without moving parts, i.e. they have no bearings that could be damaged. However, in cold regions, they need enough electricity for the integrated heating system to keep themselves free of icing. Basically, anemometers are categorized according to four measuring principles:<\/p>
