warm advection meaning in Chinese
暖平流
Examples
- The quasi - geostrophic process was diagnosed for a case of severe cold air breakout under the blocking situation during 16 - 18 march of 1998 . the attention was focused on the relationship between the surface anticyclone and 500hpa blocking high . the results indicate that the cold outbreak is associated with the adjustment of blocking situation in the ural area , i . e . the collapsing and rebuilding of the ural mountain blocking high . the temperature advections in the lower troposphere shown that the polar cold air invading from the northwest caused the ural blocking high collapsed , and a new ridge developed rapidly was due to the warm advection on the southwestern side which led to the ural blocking high rebuilt . in addition , the distribution of the vertical motion on 700hpa shown that the surface high splitting was related to the considerable upward motion located on the southeastern part of surface high
对1998年3月中旬一次高空阻塞形势下强冷空气过程进行了诊断分析，着重讨论强冷空气爆发前后地面反气旋活动与高空阻塞形势调整的关系。研究结果表明，强冷空气的爆发与乌拉尔地区阻塞形势的调整阻塞高压的崩溃和重建紧密相关。对流层下部的温度平流分析表明，阻塞形势的调整是由于阻塞高压上游西北方有冷空气侵入导致了阻塞高压的崩溃，而上游来自西南方向的强暖流则导致高压脊迅速发展，使阻塞高压重新建立。 - The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation
结果表明：在中高层暖性高压脊及地面变性冷高压稳定维持的大尺度背景条件下，地表净辐射引起的近地层冷却是大雾过程的触发和加强机制；中低空下沉气流的存在有助于近地层的弱风条件和稳定层结的建立；低层暖平流的输入和边界层的浅层抬升是大雾长时间持续的原因；伴随冷空气南下的偏北大风是驱使大雾消散的动力因子。 - The findings show that there exists overlap between macroscale convergence and warm advection if the degree of clock - wise turn dosen " t keep constant on both sides of zero doppler velocity contour about the near range of the observational site . the overlap produces vertical vapor transport and upward convergence movement favorable for formation and continuation of rain gush
结果表明：零速度带在测站近距离两侧的弯曲程度不一致是暖平流与大尺度辐合运动的迭加所造成，这一结构为暴雨产生和维持提供了有利的水汽垂直输送和辐合上升运动。
