气候漂移

  climate drift
     The most significant one is the so-called climate drift. When the components of a coupled climate system model are joined together and freed from the constraints of fixed surface boundary conditions, the statistical state of the simulated climate diverges from the initial condition (and generally from the observed climate).
     但是,耦合气候模式的气候模拟试验揭示了一个目前模式中普遍存在的问题:当耦合模式系统中的各个分量联立在一起,而且每个模式分量不再使用给定的边界强迫条件时,所模拟气候的统计状态将会逐渐偏离初始状态(也通常偏离观测到的气候状态),这种现象被称为气候漂移(Climate Drift)。
短句来源
     Results indicate that there is no climate drift in the control run and at the time of CO2 doubling the global temperature increases about 1.65℃.
     结果表明,在对照试验中没有出现气候漂移,在CO2含量加倍时全球平均地面气温将增加1.65℃。

     Further contrasts between the new schemes and the traditional one also indicate that, in discrete computational practice the new scheme in case of nondivergence is capable of enlarging the valid integral time of the corresponding traditional scheme, capable of solving its own problem of "climate drift", while at the same time improving its computational accuracy and reducing its amount of computation.
     进一步的比较数值试验还表明:在计算实践上,新方案具有在提高相应传统气象方案的计算精度,减少其计算量的同时,延长其计算时效,解决其中一类特定“气候漂移”问题方面的效用。

     This indicates that a remarkable improvement of the model climate drift level can be achieved by the actual realizing of a conserving time-difference scheme, which thereby eliminates a corresponding computational systematic error source / sink found in the currently-used traditional type of weather and climate system models in relation to the baroclinic primitive equations,
     这说明,通过构造守恒性时间差分方案消除了响应的计算性系统误差源汇,进而能够使模式气候漂移得到显著改进,而这种误差源汇存在于传统的、现仍被普遍采用的斜压原始方程天气气候模式中。

     A review of some ocean atmosphere coupling schemes based on mean monthly flux anomaly (MFA) and their applications in four coupled models is given. The performance of these models shows the modified MFA (MMFA) with a refined reference flux is more valid than the original MFA in controlling climate drift.
     该文是对基于月平均通量距平(MFA)的海气耦合方案及其在4个海气耦合的环流模式中应用情况的一个综合评述.这些模式的实施情况表明,由于采用精细化了的参考通量,修正的MFA(MMFA)比它的原型具有更为稳定的控制气候漂移的能力.

  “气候漂移”译为未确定词的双语例句
     Simulated results show that the coupled model is able to control effectively climatic drift for steady long-term integration in such a way that in the first model decade the global mean SST rises only by 0.1℃ and the global mean surface temperature only by 0.3℃. And the 50-year integrated results show that the simulated climate basically accords with the observed,and some results are better than those simulated by the uncoupled models.
     模拟结果表明,积分前10 a全球平均海表温度仅上升0.1℃,全球平均表面温度仅上升0.3℃,以后基本保持不变,模式没有出现明显的气候漂移,50 a积分显示,模式对气候态的模拟与观测基本一致,部分结果优于未耦合模式。

  climate drift
After removing the climate drift with the PCMC scheme, the coupled model is integrated for more than twenty years.
      
The results of the coupled integration show that the climate drift has been controlled successfully.
      
Results indicate that there is no climate drift in the control run and at the time of CO2 doubling the global temperature increases about 1.65°C.
      
Seen from variations of the time correlation coefficient, this model is good for the short-time climate simulation (less than two months), while for the long-time simulation, its climate drift is a little obvious.
      
A 100-year integration conducted with the coupled GCM (CGCM) shows the effectiveness of such a method in reducing climate drift.

In this paper, a meteorological traditional global pseudo-spectral scheme of barotropic primitive equation is restructed and a corresponding new perfect enstrophy conservative scheme is formulated in accordance with the principle of discrete compensation. Thus, the problems of both nonlinear computational instability and perfect enstrophy conservation retaining are completely solved, and the computational performance of the traditional scheme is improved. As the numerical experiments of the new schemes show, by solving the problem of enstrophy conservation scheme design, the new scheme in computational practice can solve their own problem of (nonlinear) computational instability and that of (nonlinear) computational convergence under certain condition. Further comparison betWeen the new schemes and the traditional one also indicates that, in discrete computational practice the new scheme applied to the case of nondivergence is capable of enlarging the valid integral time of the corresponding traditional scheme, capable of solving its own problem of "climate drift", while at the same time improving its computational accuracy and reducing its amount of computation. This principle can also be applied to the case ofbarocoinic primitive equation.
