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...
