Analysis of spatiotemporal variation characteristics of total solar radiation in Hechi from 1970 to 2021
摘要
Abstract
Based on the meteorological and geographic information data of Hechi City from 1970 to 2021,the spatiotemporal variation characteristics of the total solar radiation in Hechi City were analyzed according to the climatological estimation model of solar radiation and the methods of linear regression,anomaly analysis,Mann-Kendall mutation test and wavelet analysis.The results show that the annual total solar radiation in Hechi City presents a"decreasing-increasing"trend from 1970 to 2021,with generally stable interannual fluctuations.The four seasons show alternating processes of"darkening"and"brightening",but the trends of interdecadal change are different,and the fluctuations are more obvious in spring and summer.The total solar radiation experiences an abrupt change in 1981.The main period of the total solar radiation in Hechi City is 30 years,and it exhibits"more-less"periodic oscillations.The spatial and temporal distribution of solar energy resources in Hechi City is uneven,and there are differences in spatial and seasonal distribution,with the annual average total solar radiation ranging from 3 665.6 to 4 390.7 MJ·m-2,and the high value area being in Bama and the low value area being in Tian'e,exhibiting a gradual decrease from the south to the northwest part of the city.The total solar radiation in each season from largest to smallest is summer,autumn,spring and winter.关键词
