查询词典 southeast wind

Results show that during the snowstorm disaster, under the large scale background with "trough in south and ridge in north", strong cold air caused by prevailing northerly wind in northern Asia wedged into low level atmosphere over Southeast China and formed a "clod cushion". At the same time, warm-wet air was also transported to Southeast China by southerly wind. The vertical shear of winds from cold to warm airflows produced strong upward motion and then, the warm-wet air over the cold air wedge was driven to rise. Finally, the structure of "warm cover" and "cold cushion", as well as corresponding vertical circulation over the converging frontal zone came into being.

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 showed that two different nature of the fog (radiation fog and advective fog) have their common features. They are both formed in the zonal circulation.The abundant water vapor and thermal conditions are supplied by the southeast wind in the middle boundary layer.

The surface southeast wind is a condition for the generation of advection fog, but it contributes to the disappearance of radiation fog.

The evolution of stratification from the occurrence to the destruction in the radiation fog is from stable to unstable, while the advection fog from unstable to stable.

底层东南风是平流雾生成的条件，却对应于辐射雾的消亡；辐射雾逆温厚而强，平流雾则为弱的逆温或无逆温；辐射雾生消演变对应于大气层结由稳定发展为不稳定，平流雾则对应于由不稳定趋于稳定。
