Cut-off high pressure - Cut-off high pressure

Japanese: カットオフ高気圧 - かっとおふこうきあつ

…However, sometimes it appears in high latitudes, and the upper atmospheric pressure distribution is reversed from normal, with high pressure in the north and low pressure in the south. In this case, it almost always occurs together with a blocking phenomenon, and the high pressure in the upper atmosphere isolated in high latitudes is also called a cutoff high. [Naosuke Saito]. …

From [Cutoff]

...It is also called cut-off. In this way, the high and low pressure systems in the upper atmosphere that are separated from the main westerly wind and arranged in the opposite direction to the usual arrangement (high pressure to the south of the main westerly wind and low pressure to the north) are called cut-off high and cut-off low, respectively. Cut-off refers to the deformation of the upper atmosphere flow, and the process is explained in the attached diagram.

*Some of the terminology that refers to "cutoff high pressure" is listed below.

…しかし時には高緯度地方に現れ，上層の気圧配置が通常と逆で，北方で気圧が高く，南方で低いことがある。この場合はほとんどブロッキング現象とともにおこり，高緯度地方に孤立した上空の高気圧はカットオフ高気圧とも呼ばれる。【斎藤直輔】。…
