查询词典 multiple stratification

From the view of conservation of organic matter, the water body in evaporates basin takes on the character of density stratification; the niederschlag below mascon has high oxidation-reduction potential, which contribute to the conservation of organic matter. From the view of generation of hydrocarbon, bacteria, algae and lithology on the bottom of salt-water basin play important role in generation of hydrocarbon; furthermore, clunch from the redbeds acting as catalyzer, alkali metals making the hydrocarbon mobile.

从油气生成条件看，细菌、藻类及咸水盆地底层的岩性对油气的生成具有重要作用，此外红层中的粘土对烃类的生成起到催化的作用，碱金属可使生成的烃类发生流动；从有机质的保存条件看，蒸发岩盆地水体中具有密度分层的特点，在高密度层以下的沉积物具有强的氧化还原电位，从而使有机质保存下来。

Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。

The results show that the dynamic force and thermal conditions of forming the squall line were the convergence of cold air from Mongolia cold vortex and the warm-humid air current before west trough to form the convectional system at moderate 3 scale; the rapid development and southward shift of MβCSs was caused by a strong unstable stratification and the shear line of suitable vertical wind; a heavy hail occurred after a vertical liquid water content over 65 kg/m^2 was firstly measured by weather radar; a sharp reduction of VIL indicates that a disaster strong wind will occur at soon.

结果表明：蒙古冷涡旋转下甩冷空气与西风槽前的暖湿气流汇合，形成中p尺度的对流系统是飑线形成的前期动力和热力条件；强的不稳定层结和合适的垂直风切变导致了MβCSs的迅速发展和南压；在天气雷达首次观测到垂直液态水含量值超过65kg/平方公尺后2h内出现了大冰雹；垂直液态水含量的突然减小标志着灾害性大风的开始。
