blocking anticyclone
blocking high
Examples
- ( 3 ) obviously differences exist in the location of east - asia block high , the area of subtropical high and its position between extreme flood year and flood year in sxsp
( 3 )三峡库区夏季特涝年及偏涝年中高纬度东亚阻塞高压位置、副热带高压偏西程度及面积大小存在明显差异。 - 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。 - As a result , we find that in winter when the kuroshio is cooler than the normal , at following summer , the continental cyclone deepen and the east asia monsoon strengthen , that the mid - latitude blocking high weaken and zonal circulation develop , the east asia teleconnection of " - + - " is stired up , so that subtropical high weaken and diminish , and tend to east north , tropical monsoon trough strengthen and mei - yu front weaken , and tend to north , meanwhile south asia high weaken and diminish , and tend to eastvnorth , is easy to form eastern region type
结果发现当黑潮海温冷异常时，后期夏季大陆热低压加深，东亚夏季风偏强。中纬度阻塞高压减弱，东亚地区纬向环流发展，在东亚-西太平洋地区激发“ - + - ”的东亚遥相关型，从而西太平洋副高强度偏弱，面积偏小，位置偏东、偏北，东亚梅雨锋也偏弱，季风槽则变强，位置偏北。同时南亚高压偏弱，位置偏北、偏东，易形成东部型。 - In dry ( wet ) year , mongolia high was stronger ( weaker ) , indian low was later ( sooner ) and weaker ( stronger ) , baikal blocking high was stronger ( weaker ) , asian summer monsoon was weaker ( stronger ) , west pacific subtropical high leaned toward north ( south ) , east ( west )
这些异常表现为：旱(涝)年蒙古高压异常偏强(弱) ，印度热低压建立晚(早)且较弱(强) ，贝加尔湖阻塞高压较强(弱) ，亚洲夏季风偏弱(强) ，西太平洋副热带高压偏南(北) ，偏东(西) 。 - In 1999 , the dipole existed in between the okhotsk high and the depression in the north of northeast china , thus the okhotsk high became active and maintained , the subh was located to an area quite further south than usual . the high persisted in the east region of nw china , the cold air flowed to the mid - lower reaches of the yangtze river along the high . in the east region of nw china , air steam under troposphere was strong sinking motion , and formatted the negative vorticity region , the vapour flux divergence was divgence . lt was apparently that the rain could n ' t occur in the eastern portin of nw china . in 2000 year , okhotsk high was very weak or did n ' t exist in , there was high in the east asia - japan , the subh is located to an area further north than usual . in the east region of nw china , the trough maintained , air stream under troposphere was strong ascending motion , the cycolonic circulation was prevailing , the vapour flux divergence was intensive convergences the rain easy happened in the east areas of northwest china
4多梅雨1999年鄂霍茨克海阻塞高压与我国东北北部低压形成偶极子，使得阻塞高压稳定少动，西太副高位置偏南，西北地区东部持续受高压控制，冷空气沿此高压流经长江中下游地区上空；在西北地区东部对流层中下层气流下沉运动较强，呈反气旋涡度，水汽通量散度辐散，不利于西北地区东部降水。空梅雨2000年相反，鄂霍茨克海高压减弱甚至不存在，东亚-日本为高压，西太副高位置偏西偏北，西北地区东部处于西风槽中，对流层中下层气流上升运动增强，盛行低压环流，水汽通量散度强烈辐合，有利于降水生成。
