The invention relates to a parameter measurement and instrument orientation method for baseline wind measurement, comprising: setting two observation points, each observation point is equipped with a positioning device and a wind theodolite, and each observation point positioning device is used to obtain the Gauss at the observation point. Spatial coordinates; calculate the elevation difference, baseline length and baseline coordinate azimuth of two observation points according to Gaussian spatial coordinates; adjust the wind theodolite at the two observation points to make it orient to the north; align the wind theodolite at the two observation points Rotate to the baseline respectively to orient the wind theodolite; or correct the observation data of the wind theodolite at two observation points in real time to orient the wind theodolite. The invention is suitable for the baseline wind measurement calibration under the condition that the two observers can see or not, can effectively improve the accuracy of the wind measurement, and shorten the work preparation time.
Description
technical field [0001] The invention relates to the field of meteorological detection, in particular to a parameter measurement and instrument orientation method for baseline wind measurement. Background technique [0002] Baseline wind measurement is also called double theodolite wind measurement. During operation, a wind measurement theodolite is respectively erected at two observation points (observation point 1 and observation point 2), and the parameters of the baseline (connecting the two observation points) are measured and the theodolite is oriented. , release a weather balloon, two theodolites observe the balloon at the same time, obtain the precise coordinates (elevation angle, azimuth angle, height) of the balloon at the specified time, and calculate the wind direction and wind speed at each height, which is the only means for meteorological stations to use optical equipment for accurate aerial wind observation . In the implementation process of baseline wind mea...
