Embodiment Construction

[0031] In the following detailed description, certain exemplary embodiments of the present invention are shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not restrictive.

[0032] A set correction method for multi-climate model output results, taking a research area as an example.

[0033] (1) Select M climate models from the climate models published by IPCC and classify them. According to the characteristics of the study area, it is classified according to latitude and longitude, precipitation and landform type. Among them: according to longitude and latitude, it is divided into high latitude, middle latitude, and low latitude; according to precipitation, it is divided into arid, semi-arid, semi-hu...

Abstract

The invention discloses a multi-climate model output result set correction method, and proposes a classification method of the climate model: for example, according to longitude and latitude, according to landform type, and the like. According to the grids divided into the research area, it is judged which one belongs to the classification; combined with the proposed multi-climate model output result set calculation formula, the parameters of the formula are obtained by fitting with the measured values, and finally the corrected predicted values ​​are obtained. This correction method makes full use of data information and comprehensively considers the combination of different classification climate models. Compared with the simulation results of the previous single-optimized climate model for grids, the simulated value is closer to the measured value and more in line with the actual situation.

Description

technical field [0001] The invention belongs to the field of hydrology, and in particular relates to a multi-climate model output result set correction method. Background technique [0002] Global climate change is a hot issue that is widely concerned by governments, the scientific community, and even ordinary people. Many scientists have been paying attention to changes in temperature and precipitation, and strive to predict future trends from past and present changes. Under the background of global warming, regional precipitation shows a clear trend of increase or decrease. Climate change and its impact on regional water resources and ecology have attracted great attention from governments and scientists around the world. Scientifically predicting future climate change trends is the most important basic work for actively responding to climate change. The global climate model is an important tool for predicting future climate scenarios, and there are large uncertainties in...
