AI Technical Summary

Problems solved by technology

[0003] There are two problems in the existing large-scale simulated rainfall systems: First, these simulated rainfall systems can only realize the simulation of the rainfall process with the same rainfall intensity in the studied rainfall area

However, due to the characteristics of natural rainfall, the variation trend of rainfall intensity and its internal distribution at each point in the region have obvious inhomogeneity, that is, in the same region during the same rainfall process, the rainfall status of each point in the region is not consistent

However, the existing rainfall simulation system cannot simulate the inconsistent rainfall in the region.

Secondly, because the existing meteorological data cannot collect rainfall data at any point in the region, and there is no need to do so, but if the rainfall changes at these points are ignored in the simulation process, the result is that the simulation accuracy of the rainfall process is insufficient. The error of the simulation experiment is too large to meet the needs of scientific applications, and even lead to wrong conclusions

In short, due to the above problems, the current large-scale rainfall simulation systems in the world cannot accurately simulate the regional rainfall process, and their experimental parameters can only be used as reference data for qualitative analysis or rough quantitative analysis.
