Introduction
Maximum instantaneous wind speed is a term used in meteorological observations to refer to the highest value among the average wind speeds observed within a very short time interval (usually three seconds). It numerically represents the strongest wind blowing at a moment in time and is a key indicator for assessing extreme weather phenomena such as typhoons, squalls, and tornadoes. Unlike maximum wind speed (which is an average value over a certain period of time), maximum instantaneous wind speed captures localized, short-duration strong winds, making it essential for disaster prediction and prevention.
Applicable Scene
Maximum instantaneous wind speed is widely used in disaster prevention and mitigation. For example, it is used to predict damage to buildings and infrastructure during typhoons or low pressure periods, determine the viability of railway and air transportation, and assess the wind resistance of structures such as bridges and high-rise buildings. In agriculture, it can be used to assess the risk of lodging in greenhouses and crops. In the power sector, the safe operation of transmission lines and wind turbines also depends on the observation of maximum instantaneous wind speed. Furthermore, it serves as a crucial basis for ensuring the safety of spectators and participants during sporting events and large-scale events.
Pros: The greatest benefit of knowing the maximum instantaneous wind speed is the ability to quantitatively assess the impact of dangerously high winds occurring within a short period of time. This allows for the prediction of the risk of building damage or falls caused by squalls, which can be used for disaster prevention planning and evacuation decisions. In the design and construction fields, safety can be improved by verifying the wind resistance of structures. In the transportation and energy sectors, it can also provide a basis for determining operational or operational shutdowns due to strong winds, thereby ensuring the safety and stability of society as a whole.
Cons: Because maximum instantaneous wind speeds occur over extremely short periods of time, they are difficult to observe, and their values can vary significantly depending on the conditions at the observation site and the performance of the measuring instrument. Furthermore, localized squalls are strongly influenced by topography and buildings, sometimes failing to accurately reflect the overall situation across the entire region. Numerical models also have significant uncertainty in forecasting, making it extremely difficult to accurately determine maximum instantaneous wind speeds in advance. Therefore, it cannot be used as a single indicator but must be combined with other meteorological factors such as average wind speed, air pressure, and rainfall.
