Formation and Characteristics

The clouds in Nagasaki, Japan, are typically formed by the warm and humid air from the East China Sea rising, cooling, and condensing.

Influence on Weather and Climate

During the summer, the clouds help to regulate temperatures by providing shade and reducing the intensity of the sun’s rays. However, the clouds can also trap heat and moisture, which can make the air feel muggy and uncomfortable. The clouds are also responsible for the frequent rainfall in Nagasaki, which can bring heavy downpours and contribute to the area’s overall humidity.
