During 19–20 January 2020, the rapid intensification of an anticyclone over the British Isles resulted in the mean sea level (MSL) barometric pressure surpassing 1050hPa over south Wales and southern districts of England, for the first time anywhere in England or Wales since 1932. New long‐period records for high barometric pressure were established across south‐east Ireland, all of Wales and all of England except the north. In south‐west England, this event resulted in the highest pressures since 1905; in south‐east and central southern England, including London, the peak barometric pressure was unprecedented on a near‐continuous daily record for the London area extending back well over 300 years.

伦敦300多年来的最高气压

2020年1月19日至20日，不列颠群岛上空的反气旋迅速增强，导致英格兰南部威尔士和英格兰南部地区的平均海平面气压超过1050hPa，这是自1932年以来英格兰或威尔士地区的首次。在爱尔兰东南部，整个威尔士和除北部以外的整个英格兰都建立了新的高压大气层长期记录。在英格兰西南部，这一事件造成了自1905年以来的最高压力。在包括伦敦在内的英格兰东南部和中南部地区，大气压力的峰值是前所未有的，连续300多年的伦敦地区每日记录几乎连续。
