pressure pattern; arrangement of pressure systems
The arrangement of high- and low-pressure areas across a region, as shown on a weather map. It determines wind direction and overall weather conditions.
冬型の気圧配置になった。
A winter-type pressure pattern has set in.
天気図で気圧配置を確認する。
I check the pressure pattern on the weather map.
西高東低の気圧配置が続き、強い北風が吹いた。
A high-west, low-east pressure pattern continued, bringing strong northerly winds.
Composed of 気圧 (atmospheric pressure) + 配置 (arrangement, layout). A weather-forecast term for how high- and low-pressure systems are positioned.
COMMON COLLOCATIONS:
- 冬型の気圧配置: winter-type pressure pattern
- 気圧配置が緩む: the pressure pattern weakens
NOTE:
A frequent phrase in TV and newspaper forecasts. 西高東低 (high pressure to the west, low to the east) is the classic winter pattern that brings cold northerly winds to Japan.
