Cloud Distribution and Seasonal Patterns

The distribution of clouds in Maebashi varies with the season. During the summer months, cumulus clouds are predominant, while cirrus clouds are more common in the winter due to the drier air. Stratus clouds are prevalent during the spring and autumn, often associated with fronts and precipitation. The amount of cloud cover also varies throughout the year, with the cloudiest months being January and February and the clearest months being July and August.

Annual Precipitation

Maebashi, Japan, experiences ample annual precipitation, averaging around 1,200 millimeters (47 inches). The precipitation is relatively evenly distributed throughout the year, with slightly higher rainfall during the summer months from June to August. The summer months also tend to bring more frequent and intense rainfall due to tropical storms and typhoons.

Influence of Topography

The topography of Maebashi plays a significant role in its precipitation patterns. The city is located in the Kanto Plain, which is surrounded by mountains on three sides. This creates a “rain shadow” effect, sheltering Maebashi from some of the precipitation that falls in the surrounding mountainous regions. As a result, Maebashi typically receives less precipitation than neighboring areas at higher elevations.

Rainfall Patterns

Maebashi, Japan, experiences a temperate climate with distinct seasonal rainfall patterns. The city receives an average of 1,300 millimeters (51 inches) of precipitation annually, distributed fairly evenly throughout the year. However, certain months stand out as particularly wet or dry.

Conversely, the driest months are December and January, with average rainfall below 50 millimeters (2 inches).

Seasonal Variations

The seasonal variations in rainfall in Maebashi are primarily driven by the East Asian monsoon system. During the summer months, the warm, moist air from the Pacific Ocean flows over the Japanese Islands, bringing heavy rainfall. In contrast, during the winter months, the cold, dry air from Siberia brings less precipitation. Additionally, the city’s location near the Sea of Japan contributes to the higher rainfall during the summer months, as the moist maritime air from the ocean condenses as it rises over the mountains surrounding Maebashi.

Snowfall Patterns

Maebashi, the capital city of Gunma Prefecture in Japan, experiences significant snowfall during the winter months. Snowfall typically begins in December and continues until March, with the peak season occurring in January and February. The city is located in a mountainous region of central Japan, which contributes to its high snowfall totals. On average, Maebashi receives around 100 centimeters of snowfall annually. However, snowfall can vary considerably from year to year, with some winters receiving much more or less snow than average.

The heavy snowfall in Maebashi can have a significant impact on the daily lives of its residents. Snow and ice can accumulate on roads and sidewalks, making travel hazardous.

The combination of heat and humidity can be particularly challenging for outdoor activities and can also contribute to various health issues.

Seasonal Variations in Humidity

The seasonal variations in humidity in Maebashi are closely tied to the prevailing weather patterns. During the spring months, the city is influenced by the movement of dry air masses from the Asian continent, resulting in relatively low humidity levels. In contrast, the summer months are dominated by the Pacific high-pressure system, which brings warm and moist air from the south. This tropical air mass is responsible for the high humidity during this period.

In the autumn, humidity levels gradually decrease as the influence of the Pacific high-pressure system weakens. By October and November, the relative humidity typically falls back to around 60%, making the weather more comfortable once again. During winter, humidity levels are generally low, although occasional periods of higher humidity can occur due to passing weather fronts.
