选取兴安站1961—2006年气象观测资料,利用5年滑动平均处理方法统计分析了兴安县近46年气温、降水、湿度、日照等气候要素的变化特征。结果表明,46年来兴安县年平均气温呈增暖趋势;年降水量各年代变化不同,但总体呈增多趋势;年日照时数处于下降趋势;而平均相对湿度无明显变化趋势;同时,兴安县气候变化特征中还存在气温与降水年变化趋势之间表现出气温偏低时降水偏少、气温偏高时降水偏多现象,气温与日照的年变化趋势之间有气温偏高时日照偏少、气温偏低时日照偏多现象。
選取興安站1961—2006年氣象觀測資料,利用5年滑動平均處理方法統計分析瞭興安縣近46年氣溫、降水、濕度、日照等氣候要素的變化特徵。結果錶明,46年來興安縣年平均氣溫呈增暖趨勢;年降水量各年代變化不同,但總體呈增多趨勢;年日照時數處于下降趨勢;而平均相對濕度無明顯變化趨勢;同時,興安縣氣候變化特徵中還存在氣溫與降水年變化趨勢之間錶現齣氣溫偏低時降水偏少、氣溫偏高時降水偏多現象,氣溫與日照的年變化趨勢之間有氣溫偏高時日照偏少、氣溫偏低時日照偏多現象。
