cold anticyclone
cold high
cold-core high
Examples
- ( 5 ) . winter air temperature in north china has important relationship with the mongolia high anomaly , the east asian trough anomaly and the acreage of polar vortex anomaly
( 5 )华北冬季气温与蒙古冷高压异常、东亚大槽异常、极涡面积异常密切相关。 - 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 diagnostic analysis for the sandstorm process on the base of height , temperature , pressure and wind etc output from the model shows that the upper cold trough , low - level wind shear , surface cold anticyclonic ridge , mesoscale cyclone and cold front are the main synoptic systems , surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather , the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen , moreover , and it increases obviously the temperature of the controlled area , as a result , the updraft movement caused by convergence before front strengthens
500hpa强锋区、 700hpa切变和锋前中尺度系统的强弱及位置变化是沙尘暴天气发生发展到减弱的直接原因。地面冷高压、地面气旋及冷锋是造成本次沙尘暴天气的主要地面天气系统。地面冷高压及冷锋为沙尘暴天气的发生提供了风力条件，而中尺度气旋使冷锋前后气压梯度明显增强外，又使所控制的区域增温明显，使锋前辐合上升运动加强，为沙尘暴天气的发生提供了热、动力条件。
