[0130] In order to verify the effectiveness and accuracy of this method, the measurement data of radiosondes and the wind profile + RASS system measurement data were compared and analyzed. On October 17, 2014, a lifting waveguide appeared at 1915, and the measurement data of radiosondes and Calculated as image 3 As shown, a lifted waveguide appeared at that time. It can be seen from the figure that there is a temperature inversion phenomenon near the ground. The height of the inversion layer top is 331m, and the inversion intensity is 0.0185°C / m. It drops from 50% of the ground to 18% at 561m, thus forming a weaker uplift waveguide with a waveguide top height of 491m, M=353.8, and waveguide strength ΔM=-2.9.
[0131] Since the weather on October 17 was controlled by the northern high pressure at the test site, it was a stable weather process, and the physical characteristics of the atmosphere did not change much within a certain period of time. Therefore, the radiosonde data...
