| 1000-2000 | 0-10°C |
| 2000+ | -5 to 0°C |
Wind Patterns in Japan’s Mountains
The wind patterns in Japan’s mountains play a crucial role in shaping the country’s climate. As winds flow over the mountain ranges, they are forced to rise, resulting in an increase in speed and a decrease in temperature. This phenomenon creates an area of low pressure on the windward side of the range, leading to precipitation. On the leeward side, the air sinks, resulting in a region of high pressure, and a decrease in precipitation.
The following diagram illustrates the wind patterns in Japan’s mountains, showing the areas of low and high pressure created by the orographic lift:
In this diagram, the wind flows from the west, over the Japanese Alps, creating areas of low pressure on the windward side and high pressure on the leeward side. As a result, the leeward side experiences a reduction in precipitation, while the windward side receives significant amounts of precipitation.
