查询词典 compact convergence

The shortages of typical BP algorithm are that its convergence speed is slow and it possibly mires to local minimum. To solve the former shortage, BP algorithm was modified from several aspects, such as adjusting learning rate adaptively, adding momentum factor, preprocessing training data and modifying network structure, etc.. For the latter shortage, factor γ was introduced to avoid most of local minimum and accelerate the convergence speed.

为解决现有BP算法收敛速度慢的问题，对BP算法进行了改进，采用了动态改变步长、加入动量因子、对训练样本进行预处理以及调整网络结构等措施；针对经典BP算法可能收敛到局部极小点的问题，加入γ因子，可以避免大部分的局部极小值，从而使网络的收敛速度加快。

Results show that the heavy rainfall event occurred under the favorable environmental conditions, resulted from the interaction of mid-and low-latitude systems. The mesoscale convergence and the mesoscale low triggered the occurrence of the heavy rainfall. Rain clusters bringing the heavy rainfall were related to meso-β systems. The meso-β mesoscale rain clusters appeared to the north of the cyclone center on 1000 hPa after filtering and to the south of the meso-α convergence line on 850 hPa.

The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.

结果表明：飑线是在有利的天气形势下发生的，飑线上强风暴的强度大、高度高；飑线速度剖面图中显示有低层辐散、中层辐合、高层辐散的特征；垂直累积液态水含量迅猛增加到比较大的数值对冰雹预报有很好的指示意义；在冰雹指数产品中以强冰雹概率大于30%作为冰雹预警门限则有较好的效果；边界层辐合线起到了触发对流和加强对流的作用。

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.

为了改进和发展Gregory积云参数化方案，(1)考虑了大尺度水汽辐合对积云对流的影响，即在混合卷入中加入有组织的卷入，让有组织的卷入存在于有大尺度水汽辐合的层次上，并且与大尺度水汽辐合直接成比例；(2)考虑了过冷水存在对饱和比湿的影响，调整了初始的质量通量，并且根据对大气加热加湿的诊断，调整了大气向下拖曳的强度；(3)根据我国降水多由层状云和嵌入其中的对流云混合产生的这一特点，对于过强对流过程进行抑制，在云顶加入有组织的卷出，同时加大向下拖曳的强度，减少蒸发以降低潜热的释放，抑制过强对流的发生。
