Set kalman that this text set up strain wave assimilate system one horizontal plane net, at the vertical direction the analyticl system P for longitude and latitude, Arakawa A of lattice point, the dimension in the horizontal and vertical direction is adjustable.

本文建立的集合卡尔曼滤波同化系统是一个水平面上为Arakawa A格点的经纬度网格、垂直方向上为P面的分析系统，且水平和垂直方向上的维数均可调。。

By mesh point's symmetry,.it is improved effectively the numerical accuracy and computational stablity.

该算法网格点数少、步长均匀一致，根据格点间的对称性，减少了计算机资源的存储量。

Firstly, this paper designs a polar coordinate barotropic vorticity equation semi-spectral model and a quasi-geostrophic grid model in order to research the propagation of vortex Rossby waves and tropical cyclone intensity change entirely.

本文首先设计了一个极坐标系正压涡度方程的半谱模式、一个准地转格点模式对涡旋Rossby波传播和热带气旋强度变化进行了较为系统的研究。

The pressure ridge partly moved to southeast, it led to the cold air stream more moved to southeast, and the strong cold wave broke out. The water vapor from Caspian sea to Bslkhash lake accumulated at the upper of north Xinjiang, and it provided the water vapor condition for the cold wave. The ECMWF numerical forecast product accurately predicted the evolution trend of circulation (the position, intensity, path and speed of ground surface cold high pressure) of height field in this cold wave process. The predicted temperature at 850 hPa had good corresponding relation with the actual lowest temperature.

高压脊部分东南垮，导致强冷空气大举东南下，强寒潮天气暴发；里海到巴尔喀什湖的水汽在北疆上空聚积，为这次寒潮天气提供了水汽条件；ECMWF数值预报产品在这次强寒潮天气过程中准确的预报了高度场的环流场演变趋势，地面冷高压的位置、强度、路径和移速；850 hPa格点温度预报值与最低温度实况值具有很好的对应关系。

The second part is for the calculation of the mass spectrum for two-gluon glueballs by using Bethe-Salpeter equation. Our results are in good agreement with those given by lattice simulation and confirm that the lightest glueball is scalar with mass about 1. 7GeV, the mass of tensor glueball is about 2. 4GeV, the masses of pseudoscalar glueball and 2〓 not less than 2. 0GeV.

二是利用Bethe-Salpeter方程计算了双胶子胶球的质量谱，结果与最近的格点规范计算符合得很好，进一步肯定了标量胶球是最轻的胶球，质量约为1.7GeV；张量胶球的质量约为2.4GeV；而赝标胶球和胶球2〓的质量不小于2.0GeV。

Then, in the view of short-range weather forecast, water vapor fields in each typical process have been analyzed. The results indicate that there is significant increasing in the air column precipitable water over snow ranges when the snow is coming, snowy regions are in well agreement with the convergence regions of water vapor fluxes.

然后，利用国家气象中心T106L19全球模式的分析值格点资料等，分析各型下典型个例过程的水汽场情况，得到高原东部牧区强降雪天气前有气柱可降水量的明显增长，强降雪区与强水汽辐合区相对应，造成冬春季高原东部牧区强降雪天气的水汽主要来自孟加拉湾地区的结论。
