  inter-decadal variations
We also found inter-decadal variations in surface air temperature, including a fairly regular quasi 20-year oscillation, although its amplitude varied between different cycles.
      
The models somewhat underestimate the inter-decadal variations in interannual variability measures observed during the century and overestimate the range of anomalies.
      


Similar to numerical simulations with atmospheric global circulation models (AGCM) in the Atmospheric Model Inter-comparison Plan (AMIP), an atmospheric global circulation model is introduced to make 43 years integration by monthly observed sea surface temperatures from 1950 to 1993. We use the long-time series to discuss the inter-decadal variations of the atmospheric circulation, mainly focusing on the three key oscillations and principal circulation systems in the tropics and the Northern Hemisphere,...

Similar to numerical simulations with atmospheric global circulation models (AGCM) in the Atmospheric Model Inter-comparison Plan (AMIP), an atmospheric global circulation model is introduced to make 43 years integration by monthly observed sea surface temperatures from 1950 to 1993. We use the long-time series to discuss the inter-decadal variations of the atmospheric circulation, mainly focusing on the three key oscillations and principal circulation systems in the tropics and the Northern Hemisphere, such as Southern Oscillation (SO), Pacific-North Americal pattern (PAN), though in East Asia at 500 hPa. The results strikingly show that the inter-decadal variations, including 10-20 and more than 30 years quasi-periods oscillations are very clear. The simulation results agree with observations quite well. We also analyze the precipitation in the eastern China with the simulation data, and obtain the notable inter-decadal variations, including the climate jump in the 1960's. At the same time, the above features correspond with the variations of the atmospheric circulation in East Asia very well. Above all, we can use the GCM simulation data to investigate not only the seasonal and inter-annual variations of the amtospheric circulation and climate, but the inter-decadal virations as well.

类似大气环流模式比较计划(AMIP)的数值模拟,将实际观测的海表水温(SST)资料引入模式进行40多年的数值积分,得到长时间的大气环流模拟结果。分析数值模拟结果发现,无论是大气中的主要涛动和遥相关型,还是重要大气环流系统都极为清楚地存在着年代际变化特征,包括10~20年准周期振荡和可能的30年以上的准周期振荡;而且上述主要环流系统的形势及其年代际变化大都与实际观测资料所给出的结果相一致。顺便分析中国东部气候的模拟结果,年代际变化特征(包括60年代的气候突变)也很清楚,并同大气环流变化配合十分合理。结果也表明,同研究季节和年际变化一样,大气环流模式(AGCM)数值模拟也是研究大气环流和气候年代际变化的有效方法。

The quasi-periodicities of inter-annual variations for the inter-monthly surface air tem- perature anomaly series are diagnosed over the global, southern and northern hemispheres over the past more than 100 years (l856~ l997) by using singular spectrum analysis (SSA). The results show that there exist three dominant time scales with period ranges of 5~ 6 years, around 4 years and quasi-bien- nial oscillations in the global and both hemisphere temperature series. The first two period oscillations are the most...

The quasi-periodicities of inter-annual variations for the inter-monthly surface air tem- perature anomaly series are diagnosed over the global, southern and northern hemispheres over the past more than 100 years (l856~ l997) by using singular spectrum analysis (SSA). The results show that there exist three dominant time scales with period ranges of 5~ 6 years, around 4 years and quasi-bien- nial oscillations in the global and both hemisphere temperature series. The first two period oscillations are the most prominent. The inter-decadal variations and the variability phase of the various quasi-pe- riod oscillations are displayed in amplitude and wavenumbers as well. The above-mentioned features are obviously different in the global and both hemisphere temperature series. Singular cross spectrum analysis (SCSA) shows that there exist various couple oscillations between the inter-annual oscillations of the global air temperature series and the quasi-period signals which other sub-climate systems hint, especially the couple oscillations between the inter-annual oscillations of the global temperature and the quasi-periods signals of the sea surface temperature (SST) or South Oscillation Index (SOI).

应用奇异谱分析(SSA) 方法,对全球及南北半球近100多年(1856~1997年)逐月地面气温距平序列的年际变化准周期性进行诊断分析,结果表明,全球平均气温序列中以准5~6年和准4年周期振荡最显著,其次是准两年周期振荡。各种准周期振荡年代际演变特征及其变率的阶段性,不但表现在振幅上,而且其波数亦很明显。上述特征在全球、南北半球都各有明显的差异。奇异交叉谱分析(SCSA)表明,全球平均地面气温的年际振荡与气候系统中其他各子系统所隐含的准周期信号具有各种耦合关系,尤其表现在与Nino区海温或南方涛动指数中的准周期信号的耦合关系上

The 1951-1999 measurements are employed to investigate in depth the climatic change features of yearly and seasonal disasters, arriving at the main results as follows: a) steady increase occurs in summer rainfall in contrast to reduction, to varying degree, in other seasons, particularly in autumn; b) the possibility is great (roughly 80 %) for large-scale floods and/or droughts to be in the province on an annual basis. It is evident that the seasonal disasters hit the study region each year after 1985; c) the...

The 1951-1999 measurements are employed to investigate in depth the climatic change features of yearly and seasonal disasters, arriving at the main results as follows: a) steady increase occurs in summer rainfall in contrast to reduction, to varying degree, in other seasons, particularly in autumn; b) the possibility is great (roughly 80 %) for large-scale floods and/or droughts to be in the province on an annual basis. It is evident that the seasonal disasters hit the study region each year after 1985; c) the annual and seasonal calamities experience inter-decadal variation, and the climatic frequency of their occurrence shows noticeable change, especially in summer. The analyses from singular spectrum and maximum entropy spectrum techniques reveal that precipitation on a seasonal (summer and autumn) and an annual basis displays remarkable secular trend change with some 10-year periods found and, in contrast, about 2-year oscillations are particularly pronounced for the winter precipitation.

用1951~1999年资料详细研究了浙江省的年、季的旱、涝气候变化特征。主要结果:浙江省夏季降水量表现出稳定的增加,其他季节(特别是秋季)的降水有不同程度的减少。每年在浙江省出现大范围旱(或涝)的可能性很大(约80%)。1985年以后浙江每年都要发生大范围的季节性的旱涝。浙江省年、季降水量旱涝有年代际变化。旱、涝发生的气候频率己经有了明显的变化,特别是夏季。奇异谱分析与最大熵谱分析的结果表明夏季、秋季与年的降水量有明显的长期趋势变化,它们还有10年左右的周期,而冬季降水的2年周期振荡特别明显。
