Common cloud formations include cumulus, stratus, and cirrus clouds. Cumulus clouds are puffy and white, and they are often seen on sunny days. Stratus clouds are flat and gray, and they can cover the entire sky. Cirrus clouds are thin and wispy, and they are often seen high in the atmosphere.

Impact on Local Weather

Clouds have a significant impact on the local weather in Shirayamamachi. Cumulus clouds provide shade and can help to cool the air. Stratus clouds block sunlight, which can lead to cooler temperatures and precipitation. Cirrus clouds are thin and do not have much of an impact on the weather. In general, the presence of clouds in Shirayamamachi can lead to cooler temperatures, increased humidity, and precipitation.

Seasonal Variations

Shirayamamachi’s precipitation patterns are influenced by the monsoon winds. During the summer monsoon, which runs from June to August, moisture-laden air from the Pacific Ocean brings heavy rainfall to the region. This is also the period when typhoons, or tropical cyclones, often affect Shirayamamachi, contributing to the high rainfall. During the winter monsoon, which occurs from December to February, the prevailing winds are from the northwest, bringing cold and dry air from Siberia.

Winters tend to be dry, with snowfall uncommon in the lower elevations of Shirayamamachi.

Annual Precipitation and Variability

The average annual precipitation in Shirayamamachi is approximately 1,500 mm. However, the town experiences considerable interannual variability in rainfall, influenced by factors such as the strength of the East Asian monsoon and the frequency of typhoons. In wet years, the town can receive up to twice its average annual rainfall, leading to increased risk of flooding and landslides. Conversely, during dry years, rainfall can fall significantly below the average, resulting in drought conditions. Recent climate change projections suggest that the town may experience more frequent and intense extreme rainfall events in the future, posing additional challenges for water management and flood risk mitigation.
