同化模拟试验结果表明，卫星云图资料同化后模拟预报的降水场结果有了相当程度的改善，预报的强降水与实况比较接近。 |
| 4. | The calculating circle is very near compared with the fact . and many physical diagnose quantities thus as high vertical movement , q - vector divergence , 0 - 6 km shear etc . all contact with the rainstorm
在降水场的模拟中，降雨带的范围与实况接近，强降水中心位置和强度略有偏差，通过修正意见对提高预报准确率会有很大帮助。 |
| 5. | We also use the data from 1920 - 2000 , which were made by chen through interpolating the data of precipitation records in global land ( prec / l ) to replace the lack records of the global land precipitation dataset updated by or
还用到了陈绿文利用prec / l资料将hulme的资料插补为完整的1920 ? 2000年全球陆地降水场资料，研究了1920 ? 2000年期间发生enso事件年份的全球及区域降水异常特征。 |
| 6. | We have done intensive research on the characteristics of large scale background , rainfall field , the characteristic of mei - yu front and low in 1999 , also we confirm the close relationship between the mei - yu low and heavy rainfall , and the possible developing mechanism
我们分析了1999年的环流和大尺度背景场，降水场，梅雨锋与低涡的结构特征，并确定了梅雨锋低涡与降水的紧密联系，及发展的可能机制。 |
| 7. | In this article , the essential characteristic during meiyu and how to improve the criterion of meiyu , the effect process of circulation during meiyu , the characteristic of precipitation ' s distributing and the character between the precipitation and height are construed
文章着重探讨分析了梅雨期的系统特征及如何改进梅雨标准、梅雨期大气环流的影响过程、梅雨期的降水场分布特点以及梅雨期降水场与高度场的相关特征。 |
| 8. | The circumstance calculated by mm5 forecast system is very near compared with the real one ; . the physical quantity and precipitation calculated by mm5 forecast system should be well used in work ; the area and numeric of the precipitation forecasted by mm5 have some difference compared with the fact , that needs more some more work to make progress
该模式对这次冷涡暴雨的形势模拟与实际形势场极其接近，是一个成功的应用范例； ( 5 ) 、 mm5模式对各种物理量和降水场的模拟结果与实况接近，在精细化的定点定量预报实践中具有很好的参考价值； ( 6 ) 、 mm5模式预报降水范围和强度与实况还有一定偏差，需要进一步深入的工作来改进。 |
| 9. | In the first part of the paper , on the basis of the weather processes of huai he basin from june to august in 1998 , the difference and reliability of the two reanalysis data game and ncep from the fields of basic element , derivative , precipitation , and surface flux were studied by diagnostical and statistical methods . the results showed that the game reanalysis data is more reliable than ncep / ncar reanalysis data at the bottom and mid - high levels of troposphere , and at the precipitation and surface flux fields the case is just the same . in addition , the paper revealed that the game reanalysis data can show the evolution of the southwest vortex but the ncep / ncar reanalysis data cannot do so
在第一部分，本文以1998年6 - 8月我国江淮地区的天气过程为背景对game和ncep两组不同的再分析资料的基本要素场、导数场、降水量场和地面通量场用气候诊断和统计的方法进行了对比分析，结果表明，在对流层低层和中高层game再分析资料的基本要素场及地面的降水场和通量场较ncep再分析资料更为准确； game再分析资料能很好地反映出西南涡东移并影响江淮大暴雨的重要天气特征，而ncep资料则反映不出这一现象。 |
| 10. | Using the global land three months monthly data ( prec / l ) created by chen et al ( 2001 ) , ncep / ncar reanalyzed monthly mean wind data and global monthly sst grid data edited by british meteorological bureau , this paper investigates some problems of the climate change of global land rainfall for march - may during 1948 - 2001
用chen等( 2001 )最新创建的全球陆地月降水资料( prec l ) 、美国ncep ncar再分析月平均风场资料和英国气象局整编的全球逐月海温格点资料，分析了1948 - 2001年全球陆地3 - 5月降水场的若干问题。 |
