我国东南沿海地区城市太阳辐射变化差异及其影响因素分析
ANALYSIS OF SOLAR RADIATION AND RELATIVE FACTORS IN SOUTHEAST COASTAL CITIES OF CHINA
摘要
Abstract
Based on daily data of solar radiation and yearly data of other meteorological factors from 1961 to 2009 in six different cities,Fuzhou,Guangzhou,Shantou,Guilin,Nanning and Hangzhou,in the southeast coastal area of China,the characteristics of solar radiation change are discussed for the past 50 years with linear regression,correlation analysis,and the influencing factors of solar radiation change are analyzed with stepwise regression and path analysis.The total solar radiation in the six cities dimmed in the 1960s and 1970s,starting from 1963,1963,1963,1964,1963 and 1967,respectively.It brightened up in the 1980s and 1990s,starting in 1990,1995,1981,1984 and 1989,respectively.In the "dimmed" phase of total solar radiation,low-cloud cover is the dominant factor in Fuzhou and Guangzhou,visibility is the main factor in Shantou,Guilin,and Nanning,and total cloud cover is the main factor in Hangzhou.In the "brightened" stage of total solar radiation,total cloud cover is the first factor in Fuzhou and Hangzhou,low-cloud cover is the main factor in Guangzhou,visibility and sunshine hours are the dominant factors in Shantou,and sunshine duration (in hour) is the main factor in Guilin and Nanning.Overall,the changes of total solar radiation are mainly affected by low-cloud cover,aerosol,cloudiness,and sunshine hours.This shows that the main factor that affects the changes of solar radiation is not the same in the six coastal cities of southeastern China.关键词
