The following are the results: 1. An abstract meteorological phase parallel model for numerical weather prediction is developed as follows:〓 In this equation, parallel wall clock time related with computing grid numbers, load imbalance, communication and synchronization overhead is given out. It can be used to design and analysis the parallel algorithm.

该研究工作的主要结果如下： 1 发展提出了一个适用于气象数值预报模式的阶段并行模型MPPM：〓它表明了并行计算时间与数值模式的计算格点量、负载平衡因子、通信开销、同步开销及并行开销等之间的关系，为设计和分析数值预报模式的并行算法提供了理论依据。

For understanding the workability and precision of these prediction equations, at first this study not only simulates the MHs of Taipei, Taichung, Kaoshung cities and Kao-ping area but also compares these results with meteorological models of CLAMET and TPAQM. And the comparisons show the high correlation (up to 0.8) between them. When the results of MH prediction equations model are compared with TPAQM, they get higher or lower values than TPAQM. The reasons are that Holzworth method can not concern about the warm and cold advections effect and the upper air data used do not get enough finer space-spread. About the results spread on the domain of my model, they show more different MH fields between the land and the sea around and get more sharply change of the land MHs on daytime than TPAQM.

为了解此预测式之可行性及准确度，本研究针对台北、台中、高雄及高屏地区作混合层高度值的模拟，并将模拟结果与实际观测值、CALMET气象模组及光化学轨迹模式输出结果作比对，结果显示均有0.80以上之高相关性；但与TPAQM计算结果间有明显的高估或低估现象，此为Holzworth method无法考量温度平流效应对混合层发展之影响及探空资料空间解析度不足所致；而在空间分布上，本模式所计算的混合层高度场相较於TPAQM在海陆分布上有较明显的分野，且更能够显示出内陆地区混合层高度的日变化。

Experts from meteorological department pointed out that the reason why it snowed at that time is that the atmospheric pressure above the area dropped suddenly to 950 millibars. It was 20 millibars lower than the limit of the normal atmospheric pressure. In June, 2000, the temperature in Koppaonike City, a small town in the plain of Yugoslavia, was over 15 degrees centigrade all along. But in midday of June 17 it dropped suddenly to zero or below. Then a heavy snow fell on. This surprised the local residents. People went to street one after another to have a look.

气象部门指出，当时出现雷电的原因是当地上空气压骤降至950毫巴，比正常气压极限低了20毫巴。2000年6月，南斯拉夫平原小城科帕奥尼克的温度一直在15摄氏度以上，但17日中午，小城的温度骤降到摄氏零度以下，接着天空就飘起了大片的雪花，这一情景让当地的居民惊奇不已，纷纷上街观看。

In this paper, the rotary spectra of sea current and residual current are calculated for the data of cunent vector time series acquired through a mooring buoy located at (114°20.5'E, 20°04.8'N). Subsequently, the preliminary analysis for the internal structures of current in this area is done from these results of calculation and a lesidual current with a three days period is found in this sea area.

In this paper,based mainly on the heights above sea level of the upper limits of the modern dark coniferous forest zones in some mountainous regions and the climatic data obtained from 102 meteorological stations in China,the theoretic altitude of the forest line has been calculated and maps showing the altitude isolines of the forest line,the isolines of height differences between the permafrost limits and the forest line and the isolines of height differences between the modern climatic snowline and the forest line in China have been constructed respectively.

It is very important and critical to obtain accurate and true typhoon sea surface wind for the favoring and fine development of economy, and it is good to accelerate the study of wave, storm tide and so on.

在本论文中，我们结合气象工作者和海洋学者在台风研究中的不同侧重点，耦合自由大气和边界层过程，考察海气相互作用对台风海面风场的作用，首次将MM5应用于台风海面风场的研究之中，这对台风海面风场的研究来说是一个新的起点。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
