| 1. | The results are as follows : i there were interannual change and chronological change of summer rainfall in north china
得出了如下的一些结论： ( 1 )华北夏季降水有明显的年际、年代际变化。 |
| 2. | 3 ) the initial and final date of the rainband in middle and lower reaches of yangtze river have the obvious characteristic in interannual change in summer
3 )初夏长江中下游雨带的开始日、结束日都有明显的年代际变化特征。 |
| 3. | The importance of the interdecadal variation is similarly equal to that of interannual change in nespa variance constitution . 3 ) nespa is divided into 6 regions , and interdecadal variation is more significant in southeast than in northwest area
3 )降水异常可划分为6个主要异常区，其年代际变化的显著性东南部(南、东、中区)高于西北部(西、北、西北区) 。 |
| 4. | 2 ) the appearance frequency of strong ssw event had obvious interannual change . from the 1970s to 1980s it happened frequently , average 1 times per year . but from the 1990s it happened less , 0 . 42 times per year
2 )强ssw事件发生频数存在明显年代际变化，上世纪70年代和80年代为高发阶段，平均发生频数为1 . 0次年， 90年代起为低发阶段，发生频数下降为0 . 42次年。 |
| 5. | And for another , the correlation analysis between the real air temperature and the ncep atmosphere temperature and the analysis of interannual change show that the quality of ncep atmosphere temperature is useful in the study of climate abnormality
另外对实测气温和ncep大气半球平均气温的相关分析和年际变化分析表明， ncep大气温度的质量对于气候异常分析是可用的。 |
| 6. | The precipitation decline from september to november . the frequency of autumn flood and drought have distinct interannual changes , the trend in north and south - west region is declining and in south - west is increasing from 1990
文章还对全省范围的年、春季、冬季的气候变化进行了研究，结果表明，浙江省的年平均气温变化都是正趋势，特别是浙江省北部增温很明显，这与北半球大范围变暖的特征是一致的。 |
| 7. | The frequency of the flood and drought has distinct interannual change , floods emergence more and more from 1980 , especially in north , there are more and more droughts in north region and no flood from 1980 . in autumn , there are least precipitation in south - west region and most precipitation in south - east region , the precipitation difference between them is exceeding 95 % significance level , the difference between them is most prominent in september
浙江秋季西南区降水最少，东南区最多，它们的差异已经超过0 . 05信度值，其中9月份降水的差别最明显。另外，秋季3个区的平均降水量从9月到11月均表现为逐月减少的特征。秋季旱涝频率有明显的年代际变化，秋季浙北区和东南区旱涝频率都有减少的趋势，而秋季西南区进入90年代后，干旱的频率明显增加。 |
