Abstract: With the continuous improvement of micro-machine technique , the accelerometers have been applied more and more widely. Firstly, the stress analysis of sounding instrument in atmosphere hydro-field is supplied detailedly in this paper. Then, the mathematical model for measuring upper wind based on acceleration data is established, and the vectors of upper wind are calculated. After calculating the data from experiment, and comparing this method with the other actual measuring techniques of upper wind, the conclusion is given that the method is feasible.

Keywords: three-axis accelerometer; sounding instrument system; wind measuring model; wind speed; wind orientation
