氣候特征

三湖(hu)保護區(qu)處于北(bei)溫(wen)(wen)(wen)帶大陸性季(ji)風(feng)(feng)氣候區(qu)內(nei)。四季(ji)分明，年、日較(jiao)差大。春季(ji)干燥多(duo)風(feng)(feng)?夏季(ji)溫(wen)(wen)(wen)熱多(duo)雨?秋季(ji)晴(qing)爽(shuang)?冬(dong)季(ji)嚴寒?年平均氣溫(wen)(wen)(wen)在1.9℃～4.4℃之間?極(ji)端高(gao)溫(wen)(wen)(wen)36.6℃，極(ji)端低溫(wen)(wen)(wen)-45℃。年≥10℃積溫(wen)(wen)(wen)為(wei)1900℃～2800℃,并呈由南(nan)至(zhi)北(bei)增加(jia)趨勢?年日照時(shi)數(shu)2350～2450小(xiao)時(shi)?年降水量(liang)由南(nan)向北(bei)略(lve)有減少，為(wei)834～673毫米之間。無霜(shuang)期(qi)大致為(wei)110～130天(tian)。一月(yue)平均氣溫(wen)(wen)(wen)約(yue)為(wei)－18℃，七月(yue)平均氣溫(wen)(wen)(wen)約(yue)為(wei)20℃左(zuo)右(you)。該區(qu)夏季(ji)盛行西(xi)南(nan)風(feng)(feng)，冬(dong)季(ji)盛行西(xi)北(bei)風(feng)(feng)。

保護區(qu)由于受到三(san)個湖(hu)泊(bo)及(ji)森林(lin)等(deng)因素(su)影響(xiang)，又(you)具有湖(hu)泊(bo)氣(qi)候、谷地氣(qi)候和森林(lin)氣(qi)候的復合特(te)征。
