摘要
利用漯河1956～2008年的观测资料,运用一元回归方法,分别分析了月、季、年的平均气温、降水量、日照时数这3个气象要素随时间的变化趋势,并对回归方程进行了F统计显著性检验。结果表明,漯河气候整体显著变暖。季节变暖比单个月可靠,年平均气温变暖比分季节更显著、更可靠。漯河仅在4月降水量显著减少。漯河日照时数整体呈减少趋势。季、年日照时数变化比单个月更显著、更可靠。
Based on the data observed from 1956 to 2008 in Luohe, by means of regression method, the change trend of average temperature, precipitation and sunshine in month, quarter and annum are analyzed respectively. F-test is used to examine the regression equation. The results show that Luohe climate presents warming on the whole. The seasonal warming is more reliable than the individual month. Warming trend of annual average temperature is more pronounced and more reliable than the seasonal. Luohe precipitation is significantly reduced only in April. Luohe sunshine hour appears reduction in general. Variations of quarterly and annual sunshine hours are pretty obvious than the individual month.
