Japan Barometric Pressure Map
Depending on how many places we monitor in Japan, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Weather Systems
Japan is affected by large weather systems like the Siberian High in winter and the Pacific High in summer. These systems create areas of high or low air pressure that move across the country, causing changes in wind, clouds, and rain.
Geography
Japan’s mountains and long, narrow islands change how air pressure spreads. Mountains block or channel winds, so air pressure can be higher on one side and lower on the other. Coastal areas feel changes faster than places sheltered by mountains.
Seasonal Cycles
In winter, cold air from Siberia creates high pressure over northern Asia and pushes cold winds toward Japan. In summer, warm air from the Pacific forms high pressure and brings hot, humid weather. Spring and autumn have shifting pressure as these systems switch places.
Climate Change
Climate change is making air pressure patterns less predictable. Warming oceans and air lead to stronger storms and heavier rainfall. High and low pressure areas may last longer or move differently than before, which can cause more extreme weather in Japan.
