Formation and Types

Clouds in Kiryu, Japan, are primarily formed by the condensation of water vapor in the atmosphere. The city’s location in a humid subtropical climate provides ample moisture for cloud formation. During the summer months, warm, moist air from the Pacific Ocean rises, cools, and condenses to form cumulus clouds. These clouds are often puffy and have a distinct cauliflower-like shape. As they develop vertically, they can transform into towering cumulonimbus clouds, which are associated with thunderstorms and lightning.

In the winter months, cold air from the northwest brings clear skies and fewer clouds. However, when the air mass is unstable due to the presence of warm and cold fronts, stratus clouds or nimbostratus clouds may form. These clouds are characterized by their uniform gray appearance and can cover the entire sky, leading to overcast conditions and drizzle or rain.

Seasonal Humidity Patterns

Throughout the year, Kiryu, Japan, experiences significant variations in humidity levels. During the summer months of June to September, the city is characterized by high relative humidity, ranging from 70% to 85%. This is due to the combination of warm temperatures and moist air from the Pacific Ocean. In contrast, the winter months of December to February are much drier, with humidity levels typically between 45% and 60%. The cold temperatures and reduced precipitation during this time contribute to the lower humidity.

Factors Influencing Humidity

The humidity in Kiryu is primarily influenced by several key factors. One of the most significant factors is the prevailing weather patterns. During the summer, the city is often affected by warm fronts and moist air masses moving across the Pacific Ocean. These conditions result in increased cloud cover and precipitation, which contribute to higher humidity levels. In winter, however, prevailing cold fronts and dry air masses from the Siberian interior bring colder, drier conditions, leading to lower humidity. Additionally, the proximity of Kiryu to the ocean plays a role in its humidity levels. The city’s location on the edge of the Kanto Plain allows moist ocean air to easily reach the area, especially during the warmer months.

Wind Patterns and Speed

Kiryu, Japan, is located in the Kanto region of central Japan and experiences a humid subtropical climate with distinct seasonal changes. The wind patterns in Kiryu are primarily influenced by the seasonal shift of the prevailing wind systems and the local topography. During the winter months, the strong northwesterly winds, known as the “winter monsoon,” bring cold, dry air from Siberia across the country. These winds tend to be stronger in the morning and evening and can reach speeds of up to 15 meters per second (33 miles per hour).

In contrast, during the summer months, the prevailing wind direction shifts to the southeast, bringing warm, moist air from the Pacific Ocean. These winds, known as the “summer monsoon,” are generally weaker than the winter winds and typically reach speeds of around 10 meters per second (22 miles per hour). The summer monsoon winds contribute to increased humidity and precipitation in Kiryu.

Seasonal Variations

The wind speed and direction in Kiryu vary significantly throughout the year. In January, the coldest month, the average wind speed is approximately 12 meters per second (27 miles per hour), with strong gusts reaching up to 20 meters per second (44 miles per hour). In contrast, in August, the warmest month, the average wind speed drops to around 9 meters per second (20 miles per hour), and gusts are generally weaker. The seasonal variations in wind speed and direction are primarily driven by the changes in the prevailing wind patterns and the temperature gradients between different regions of Japan.
