Research on Rainfall Factors in Zhengzhou Based on Gray Correlation Analysis
Abstract
this paper,and significance tests were performed to determine whether they were correlated and the strength of the correlation.
At the same time,considering the small data samples and the existence of data errors,gray correlation analysis can be used,and
then the main effects of dew point,air temperature and wind speed on the variation of precipitation can be derived.The years
2003,2004,2016,and 2018 with high precipitation were screened out through M-K mutation test,cluster analysis based on the
characteristics of total annual precipitation and number of days of rain during the year.
