Analysis of the Impact of Climate Change on the Areas along the Sichuan-Tibet Railway

摘要

In order to further study the impact of climate change on the areas along the Sichuan-Tibet Railway, this paper uses the daily data set (V3.0) of China’s surface climate data, and through various methods such as time division, correlation analysis, etc., the meteorological elements along the railway were analyzed in detail. Studies have shown that the precipitation in the areas along the Sichuan-Tibet Railway is mainly concentrated in summer. Autumn and winter are dry periods, and there is a high probability that it will not rain. From the precipitation anomaly, it can be analyzed that the probability of flooding and drought disasters along the Sichuan-Tibet Railway is very small. The average temperature increases with the age. The probability of extreme high temperature events in the study area is very small. The average annual wind speed has an upward trend throughout the four seasons. The average wind speed in spring is the largest, but the daily wind speed fluctuates little. There are no windy days, and the probability of strong winds in autumn and winter is 0.1%. Relevant research results can provide scientific reference and basis for the construction of Sichuan-Tibet railway project.
