Formation and Characteristics

The clouds in Nakatsu, Japan, are primarily affected by the city’s geographical location and subtropical climate. Nakatsu is situated on the coast of Kyushu Island, facing the warm Kuroshio Current. The interaction between the warm ocean waters and the cooler air above creates a favorable environment for cloud formation. Cumulus and stratocumulus clouds are common throughout the year, with their appearance and behavior influenced by the local topography and prevailing wind patterns.

During the summer months, the subtropical high-pressure system brings in warm and humid air from the Pacific Ocean. This creates an unstable atmosphere that promotes the formation of cumulus clouds. These clouds often develop into towering cumulonimbus clouds, which can produce heavy rain showers and thunderstorms. In contrast, during the winter months, the prevailing winds shift to the northwest, bringing in colder and drier air. This results in a more stable atmosphere and fewer clouds in the sky. Clear skies and calm winds are common during this time of year.

Monthly Precipitation Pattern

Nakatsu experiences distinct seasonal variations in precipitation throughout the year. During the wet season, which typically spans from May to September, the city receives substantial rainfall, with monthly precipitation often exceeding 200 mm (8 inches). The peak of the rainy season occurs in June and July, when heavy downpours are common. In contrast, the dry season, from October to April, brings significantly less precipitation, with average monthly rainfall dropping below 100 mm (4 inches). This season is characterized by relatively stable atmospheric conditions and fewer rainy days.

Interannual Variability

While Nakatsu’s monthly precipitation patterns are relatively consistent, there can be significant interannual variability. Some years experience extended periods of heavy rainfall during the wet season, leading to flooding and other water-related hazards. In contrast, other years may experience droughts, with below-average precipitation levels causing agricultural losses and water shortages. This variability is primarily influenced by large-scale climate patterns, such as the El Niño-Southern Oscillation (ENSO) and the Madden-Julian Oscillation (MJO), which can alter atmospheric circulation patterns and affect precipitation distribution.
