摘要
Abstract
Using the monthly sunshine hours data of Shidao Area in 1981—2010, the conventional statistic methods and wavelet transform to analyze the distribution of sunshine and change rule. The results show that the Shidao Area sunshine time exist periodic variation characteristics of multiple time scales:there are 3 a in decadal variability and 18 a characteristic time scales;the 1618 a existed more than 1997 years ago, 57 a change ,then there is 45 a change in Spring;there are 811 a cycle of change, in 1987 years ago for 57 a, 1988—2003 for 810. A, 2003 after there is a cycle of about 6 a in whole Summer; there are 67 a cycle after cycle in 23 a basic before 1986 in Autumn; there are 1416 a and 57 a cycle in Winter. Shidao sunshine time downward trend obviously, especially in recent 10 a in Winter. The future will be in the midst of a sunshine hours less in the short term.关键词
