辐散

It is shown that over the top layer of a heating region, although there is no diabatic heating, but still exist ascent, divergence, anticyclonic circulation, and cold center.

在加热区的上空尽管非绝热加热为零，仍然存在上升、辐散、反气旋环流及冷中心，证明这是由于"过流"引起的。

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。

The weakening of pressure gradient between thecontinent and ocean can excited an anomalous anticyclonic circulation over the continent,leading to the weakening of the southwesterly over the north and central SCS.

另外从辐散风场来看，南海中南部地区的上升运动的加强很大程度上与赤道东太平洋地区海温的显著增加有密切联系。

The strongest upwelling of the Circumpolar Deep Water is expected to occur at the Antarctic Divergence(73°E,64°S) and in the region center with(0°E,65.5°S).

在南极辐散带(73°E，64°S)和0经度断面上(0°E，65.5°S)两处有明显的SST涌升高值区。

Using the NCEP/NCAR 1°×1° analysis data with a time resolution of 6 h, the Regional Spectrum Model reanalysis data from Japan Meteorological Agency with a horizontal resolution of 20km and a time interval of 6 h, we decompose the horizontal wind of super-intensity Typhoo SAOMEI (0608) based on the H-C method. The two parts are called the nondivergent and the irrotational components, respectively.

利用NCEP/NCAR 1°×1°的实时分析资料和日本气象厅区域谱模式20km分辨率的再分析资料，利用调和-余弦算法得到的无辐散风分量和无旋风分量，对2006年的8号超强台风"桑美"进行风场结构的比较分析。

10W's outflow is improving, shear is minimal and sea surface temperature is high in South China Sea.

10W 的辐散良好，且正处於低垂直风切变和高水温的环境。

Under same boundary conditions and same space difference, the results of 6-hour simp...

试验结果还指出要作比较正确的夏季低纬度等压面形势场的预报，由于无辐散层的倾斜，山地的影响，气压场及变化微弱，以及观测与分析的误差，如谋求准确的预报，尚有待于进一步的研究。采用过于简化的模式，是不易成功的。

Using a forced dissipative nondivergent nonlinear barotropic vorticity equation and by means of various schemes, we did simulation experiment and get its numerical solution .

从强迫耗散无辐散正压涡度方程出发，用不同方案模拟试验得到它的数值解，它与已经导得解析解的特征较为一致。

Following the above conditions,anomalous southerlies transport water vapor to the north and cause moreprecipitation over there.The key condition for the above-normal production year is that SST anomalies over the northwesternportion are warmer than that over the southeastern portion during the winter season.

在此南北分布状态下，风场与辐散风距平均由南向北吹，不仅降低北区冬季东北季风强度，亦将热带水汽往北传送，让北方海域之大气总含水量增加，藉由辐合距平之举升机制，降水量亦随之增加，而水汽递出之南方海域则是二者皆减少。

Basing on the Doppler reflectivity map, the entire precipitation rain bands were apparent westward rotation process. And basing on Doppler radial velocity map, the configuration of low-level convergence with high-level divergence is conducive to the precipitation occurrence and development. The rainstorm resulted from the cloud band maintaining over the rainfall zone.

从多普勒反射率因子图上，整个降水雨带为明显的旋转西进过程；多普勒径向速度图上，低层辐合高层辐散的配置有利于降水的发生发展，暴雨是长时间维持在其上空的强降雨云带造成的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
