Abstract
Description
Technical Field
[0001] The present invention relates to the field of comparative inspection, and in particular to a method for comparative inspection of multi-parameter spatiotemporal movement of an operation effect area. Background Art
[0002] In recent years, with the continuous development of the national economy, society and industrialization, while it has brought convenience to people, it has also brought some negative effects. Meteorological disasters such as drought, rainstorms and strong winds have occurred frequently. In order to solve these problems, the demand for artificial rainmaking to resist drought, artificial hail prevention and artificial rain reduction has continued to increase, and artificial weather modification has received more widespread attention. With the increasing number of artificial catalytic operations, the unavoidable problem is that we need to know whether the operation is effective. However, the effect inspection after the operation is also a difficulty in artificial weather modification.
[0003] The effect test after the operation can be divided into physical test, statistical test and numerical simulation. Statistical test is a basic effect test method, including randomized and non-randomized schemes. The more famous randomized experiments include Israel's random cloud seeding experiment and the United States snow enhancement experiment. To use statistical tests to evaluate the effect after the operation, random experiments should be conducted, and statistical data should be used in random experiments. However, since the randomized experiment has a long test cycle and requires a large number of test samples, it is difficult to exclude uncertain factors such as natural clouds. Therefore, the operation method in actual business is usually non-randomized; for numerical simulation tests, model tests are to add cloud catalysis schemes to the model schemes to evaluate the effect after the operation, which depends on the accuracy of the numerical model; physical tests are to obtain the effect of the operation by studying the changes in physical parameters in the cloud precipitation process after the cloud is affected. For example, some studies have observed cloud trenches or strong echo bands formed by a large number of small ice crystals after cloud seeding on satellites and radars, but physical tests cannot directly give quantitative results, and are not very applicable when quantitative results are needed in many cases. Therefore, Kou Dai invented a multi-parameter spatiotemporal mobile comparison test method for the effect area to improve the accuracy, timeliness and precision of the effect test. Summary of the invention
