In the present paper wind observation was discussed in view of meteorological services in Japan. The main purpose of the wind observations at meteorological observatories is to collect data for numerical weather prediction use as initial values. Collected data arc processed by quality checks, initialization and 4-dimensional assimilation technique, and then converted to 3-dimensional grid point values. In spite of some concerns of representativity of the meteorological stations, therefore the present surface observational system is suitable for collecting these data.For calculating design wind speed by using wind data collected at meteorological stations we should adopt some correction techniques for evaluating effects of changes of anemometers and observational conditions. For this purpose wind tunnel test and numerical simulation techniques will be considered.
