关于正压大气对称运动和非对称运动的数值试验

利用正压原始方程谱模式进行了3个不同情况的数值试验。发现试验结果和在正压过 滤模式的情况很相似,即: 1.在无地形起伏时,如初始时刻运动是对称(来赤道来说,以下同)的,则以后运动将永 远是对称的; 2.在地形为对称时,如初始时刻运动是对称的,则以后运动仍将是对称的; 3.反对称的地形分布可以引起反对称运动,从而,使初始时刻对称的运动变为非对称运 动。 为了解释这些结果,用作者曾在正压过滤模式中用过的方法进行分析,证明它们在理论 上是成立的。还发现:如初始时刻运动是反对称的,则以后将变成非对称的,即纯粹的反对 称运动不可能维持。 Three numerical experiments have been made by using a spectral barotropic primitive equation model.

NUMERICAL EXPERIMENTS IN SYMMETRIC AND ASYMMETRIC MOTIONS IN THE BAROTROPIC PRIMITIVE EQUATION MODEL ATMOSPHERE

Three numerical experiments have been carried out by using a spectral barotropic primitive equation mo-del.It is found that the results obtained are quite similar to those with the barotropic filtered model.Themain results read as follows:(1)In the case with symmetric orography or without orography,if the motion is symmetric(with re-spect to the equator,the same is true hereafter)at the initial instant,then it would be symmetric afterwards.(2)The antisymmetric orography distribution could cause antisymmetric motion,and the original sym-metric motion might become asymmetric.In order to explain the above results,it has been proved that they are theoretically valid.And it is foundthat if the motion is antisymmetric at the initial instant,then it would become asymmetric.Therefore,nopure antisymmetric motion could be maintained.

Forward–backward scheme on the B/E grid modified to suppress lattice separation: the two versions, and any impact of the choice made?

Ever since its introduction to meteorology in the early 1970s, the forward–backward scheme has proven to be a very efficient method of treating gravity waves, with an added bonus of avoiding the time computational mode of the leapfrog scheme. It has been and it is used today in a number of models. When used on a square grid other than the Arakawa C grid, modification is or modifications are available to suppress the noise-generating separation of solutions on elementary C grids. Yet, in spite of a number of papers addressing the scheme and its modification, or modifications, issues remain that have either not been addressed or have been commented upon in a misleading or even in an incorrect way. Specifically, restricting ourselves to the B/E grid does it matter and if so how which of the two equations, momentum and the continuity equation, is integrated forward? Is there just one modification suppressing the separation of solutions, or have there been proposed two modification schemes? Questions made are addressed and a number of misleading statements made are recalled and commented upon. In particular, it is demonstrated that there is no added computational cost in integrating the momentum equation forward, and it is pointed out that this would seem advantageous given the height perturbations excited in the first step following a perturbation at a single height point. Yet, 48-h numerical experiments with a full-physics model show only a barely visible difference between the forecasts done using one and the other equation forward.

A numerical method of statistical pattern recognition

A numerical method of statistical pattern recognition is proposed in this paper. Different from the discriminatory analysis method currently used in the mathematic statistics, it is unnecessary to assume that the predictand should be subject to a certain distribution. On the contrary, the statistical relationship between predictand and predictor has been obtained directly with computer according to actual distribution to recognize the category of patterns. Result of forecast has been improved as compared with the usual analytic discriminatory method. The influence of predictor on predictand can be seen clearly from this method and the transparency is good. Therefore, it is better to use the method in very short range forecast for which causality is more obvious.     

The Surface Friction and the Flow over Mountain

The flow over mountain is quite complicated. There are a lot of papers on this problem and a lot of progresses have been made. However, in the most of these papers, just the dynamics contributions of mountain have been analysed; the effect of the friction is often neglected. Since the frictional effect is always associated with flow, especially when it flows over the mountain. The study shows that the friction is small in the magnitude but it is not a negligible effect because it changes the features of the flow. In the case of super-or sub-critical flow, there are two extremes: one maximum, one minimum of the fluid surface on the lee-side of the mountain, while in the inviscid fluid, there is just one extreme. The frictional effect should neither be too strong nor too weak to make the situation happened according to the investigation of this paper.     

Mann–Kendall trend analysis of tropospheric ozone and its modeling using ARIMA

The present work reports studies on the spatial distribution of tropospheric ozone extending over both southern and northern hemispheres. This study is based on a univariate approach to the spatial data series obtained at regular spatial intervals. Mann?CKendall's (MK) trend analysis has been carried out to discern the trend within the spatial distribution of the tropospheric ozone, and it has been observed that in all seasons, except monsoon (JJAS), there is a linear trend within the spatial distribution. Studying both monthly and seasonal behavior through autoregressive integrated moving average (ARIMA), it has been revealed that ARIMA (0,2,2) can be used as a representative of the spatially distributed tropospheric ozone over southern and northern hemispheres. The representative model has been confirmed through the study of Willmott's index and prediction yield.
