Cloud Types Observed in Itami, Japan

Itami, Japan, located in the south-central region of Honshu, experiences a wide variety of cloud formations due to its temperate climate and proximity to the sea. The city lies in a transition zone between the Köppen climate classifications of humid subtropical (Cfa) and humid continental (Dfa), resulting in distinct seasonal variations in cloud cover.

During the summer months (June to August), Itami witnesses frequent convective activity leading to the formation of cumulus and cumulonimbus clouds. These clouds often appear as puffy, white masses that can grow vertically into towering thunderheads, especially in the late afternoon and evening. During winter (December to February), the city experiences a shift towards stable air conditions, favoring the development of low-level stratocumulus and stratus clouds. These clouds often cover the sky with a uniform gray layer, reducing sunlight and creating a gloomy atmosphere.

Seasonal Variation and Cloud Cover

Throughout the year, Itami’s cloud cover undergoes significant seasonal variations. In winter, the city experiences the most significant cloudiness, with an average of 65% of the sky obscured by clouds. This is primarily due to the prevalence of low-level clouds and the frequent occurrence of precipitation. In contrast, summer brings the lowest cloud cover, averaging around 45%. The warm and unstable conditions during this season promote the development of convective clouds, which tend to be more isolated and allow for clearer skies.

Spring (March to May) and autumn (September to November) serve as transitional seasons, transitioning from the winter and summer cloud patterns, respectively. Spring exhibits moderate cloud cover, averaging 55%, and often features a mix of stratocumulus and cumulus clouds. Autumn, on the other hand, witnesses a decrease in cloudiness compared to spring, averaging 50%. This gradual decline in cloud cover reflects the shift towards more stable atmospheric conditions as winter approaches.

The average rainfall during this period is around 220-250 mm per month, with some years receiving even higher amounts.

In contrast, the winter months (December to February) are typically drier in Itami. The monsoon winds weaken during this time, and the city comes under the influence of continental air masses.

The dry season extends from December to February, with humidity levels typically dropping below 60%. These seasonal variations are primarily driven by the influx of moist air from the Pacific Ocean during the summer and the prevalence of cold, dry air masses originating from Siberia during the winter.

Diurnal Fluctuations

Humidity in Itami also undergoes diurnal fluctuations, with higher humidity levels typically occurring in the early morning and late evening. During the day, as the sun heats the air, it becomes less able to hold moisture, resulting in lower humidity. As the air cools at night, its capacity to hold moisture decreases, leading to higher humidity. These diurnal variations can be particularly pronounced during the summer months when the temperature difference between day and night is greatest.

Wind Patterns in Itami, Japan

These winds often carry moisture from the Pacific Ocean, leading to frequent rainfall.

Impact on Local Climate

The prevailing wind direction has a significant impact on Itami’s local climate. The strong southerly or southwesterly winds during summer contribute to the city’s humid and rainy conditions. During winter (December to February), the northeast monsoon brings cold and dry air from Siberia, causing winds to shift to the north or northeast. These winds can be strong and occasionally gusty, contributing to colder temperatures and clear skies. Additionally, Itami’s proximity to the Sea of Japan influences the city’s wind patterns, bringing occasional strong winds and precipitation associated with passing weather systems.
