Abstract

The invention provides a gravity wave parameter calculation method and device and a terminal, and relates to the technical field of gravity wave. The method comprises the following steps of: obtainingan original temperature profile on the basis of detection data obtained by detecting atmospheric temperature by a sounding rocket; fitting the detection data by adoption of a preset processing methodso as to obtain a background temperature profile, wherein the preset processing method comprises a moving average polynomial fitting method with a filter coefficient or a Kalman filter algorithm; solving a difference value between the original temperature profile and the background temperature profile so as to obtain a temperature disturbance profile; and calculating a gravity wave parameter on the basis of the temperature disturbance profile, wherein the gravity wave parameter comprises gravity wave spectrum power density. According to the method, the correctness of the gravity wave parameter can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of gravitational wave research, in particular to a calculation method, device and terminal for gravitational wave parameters. Background technique [0002] Gravity waves play an important role in the stratosphere, which can cause large temperature and wind field disturbances. At the same time, the force generated by gravity wave fragmentation can change the background wind field. In addition, the mid-level atmospheric circulation is also affected by gravity waves. The accuracy of the atmospheric circulation model depends on The parameterization accuracy of gravity waves in the middle atmosphere, so the calculation method of gravity wave parameters is very important. [0003] In the process of using the temperature profile to calculate the gravity wave parameters in the prior art, most of them involve the traditional cubic polynomial fitting method. However, the disturbance temperature calculated by t...
