查询词典 rainfall distribution

While indirect assimilation experiment is better than that of non-assimilation one in rainfall center, the former appears positive role.2 Radar observations direct assimilation experiments: By means of ARPS-3DVar and ADAS (ARPS Data Analysis/Assimilation System), CINRAD observations are assimilated only with NCEP reanalysis data for the forecast of rainstorm. Results show that meteorological element fields are improved observably by assimilation experiments.

While indirect assimilation experiment is better than that of non-assimilation one in rainfall center, the former appears positive role.2 Radar observations direct assimilation experiments: By means of ARPS-3DVar and ADAS (ARPS Data Analysis/Assimilation System), CINRAD observations are assimilated only with NCEP reanalysis data for the forecast of rainstorm.

以面向雷电预报的雷达、卫星遥感资料同化及其应用为研究目的，利用NCEP资料、新一代多普勒雷达网、FY2C气象卫星、闪电定位仪网、自动气象站等观测资料的诊断、同化模拟以及理论分析等方法，对气象遥感资料的同化设计及其在雷暴天气条件下雷电预测方面的应用进行了综合研究和初步分析。

Furthermore data assimilation experiments are conducted with MM5 Adjoint-model Assimilation System made by adjoint codes. With a case of heavy rainfall taking place from 00h July 23 to 00h July 24,2002, several numerical simulation experiments of different schemes are performed. The results are as follows. MM5 Adjoint-model Assimilation System not only can improve the initial field effectively and promote the coordination with the model but also can enhance the forecast on the precipitation and other elements. The assimilation of CDW has an improvement on quality of upper wind. The effect of direct numerical simulation with utilizing the CDW to amend the initial field gains the advantage over the one not.

结果表明，MM5伴随模式同化系统能有效改善初始场与模式的协调能力，提高模式对于降水场和其它要素场的预报；使用云导风资料修正初始场后直接模拟的效果比未使用时直接模拟的效果要好，对部分区域的强降水预报精度有一定程度的改善；使用伴随模式同化系统后，加入云导风资料的同化试验对其它要素的改善与直接同化常规资料的效果相比，改善优势不明显，但从各要素的误差来看，对于风场的改善最好。

The warm and wet air before an eastward upper trough from Hexi creep up on the Wedge of cold air, and produce the heavy rainfall.

In addition, it establishes math model about the best benefit in condition of different crop with different condition. Making computer analogue test with the example of Guantao county in Handan, the result shows that it reaches the goal of exploiting and using water resource reasonability by adjusting the agriculture pattern of plant and other related measure, through which the rainfall resource can be self-balance satisfy every agricultural need in one district in one year or many years.

另外建立了不同条件下种植不同作物获取最优效益的数学模型，以邯郸馆陶县为实例进行了计算机模拟计算，输出结果分析说明通过种植结构调整等相关工程措施达到了合理开发利用水资源的目的，最终确定适当的工程措施和农业种植结构，使研究区内的雨水资源量达到年内或多年的自平衡的灌溉模式。

This might be one of the reasons that caused the rain belt anomalously southward for the summer of 1997 and 1999. In addition, the phase-locked west and south wind phases of the 30-60 day low-frequency oscillations happened together made obvious contributions to the heavy rainfall to the south of the Yangtze River Valley.

另外，在中国东部30°N及其以南地区，30～60天低频振荡的西风和南风位相锁相的叠加，对这两年夏季长江流域及其以南地区的降水做出了贡献。

The results show that:(1) the dynamical conditions for returnflow events are a little different from other rainfall events, with divergence and anticyclonic circulation at lower levels;(2) the air of the returnflow from Northeast China, through the Bohai Sea, then to North China, is relatively dry.

结果表明：涡度和散度的垂直分布与一般的降水过程不同，低层存在辐散和反气旋环流；自东北南下经渤海回流到华北平原的空气是比较干的。该文分析结果有助于预报业务人员了解回流天气，提高华北回流天气的预报准确率。
