Analysis on the temperature variation characteristic in recent 60 a in Ningbo under new standard(新标准下宁波市近60年气温变化特征分析)
利用1953~2013年宁波地区逐日气温观测资料,根据1981~2010年新30 a标准,分析了宁波市年平均气温、季平均气温、极端最高气温、极端最低气温、高温日数、低温日数等要素的变化趋势和特征,在此基础上统计了暖冬、冷冬、酷暑、凉夏的出现次数.通过统计分析发现:近60 a来宁波市的年平均气温、季平均气温、极端最高气温、极端最低气温都表现出增暖趋势,增温最明显的时段集中在20世纪90年代至今,春季增温最为明显,冬季次之,夏季增温幅度最小;极端最低气温升温速率比极端最高气温略快,高温日数增加,低温日数减少,暖冬和酷暑出现的次数远高于90年代以前.气温变化特征说明,20世纪90年代以来宁波市增暖是...
