The rainy season typically lasts from May to September, with June and July being the wettest months.
Distribution and Types of Clouds in Nantou
Nantou, a county in central Taiwan, experiences a wide range of cloud formations due to its mountainous terrain and subtropical climate. The mountainous regions of the county are particularly prone to orographic clouds, which form when moist air is forced to rise over a mountain barrier. As the air rises, it cools and condenses, forming clouds such as stratocumulus and altocumulus. These clouds often appear as layers or sheets and may have a patchy or broken appearance.
In the lower-lying areas of Nantou, cumulus and cumulonimbus clouds are common. Cumulus clouds are characterized by their puffy, cauliflower-like shape and are typically associated with fair weather. However, when these clouds grow vertically and develop an anvil-shaped top, they become cumulonimbus clouds, which are associated with thunderstorms and precipitation. In the summer months, towering cumulus clouds often form over the county, particularly in the afternoons, and can sometimes produce brief but intense thunderstorms.
Annual Precipitation Patterns
Nantou, Taiwan experiences a subtropical climate characterized by abundant rainfall throughout the year. Annual precipitation averages around 2,500 mm, with the rainy season typically extending from May to September. During this period, heavy downpours are frequent, often caused by the arrival of typhoon systems from the Pacific Ocean. The monsoon winds bring moisture-laden air, resulting in higher precipitation levels during the summer months. In contrast, the winter months (December to February) witness relatively less rainfall due to the prevalence of cold, dry air masses.
Seasonal Variations
The monthly distribution of precipitation in Nantou shows a distinct pattern. June and July are the wettest months, with average rainfall exceeding 400 mm. September and October also receive significant rainfall, while November and December mark a transition to drier conditions. From January to April, precipitation levels are relatively low, averaging around 100-150 mm per month. This seasonal variation in rainfall influences the region’s agriculture and water resources, with farmers relying on irrigation during the drier months. Additionally, the monsoon season can bring heavy rainfall and flooding, which requires proper infrastructure and disaster preparedness measures to mitigate potential hazards.
Seasonal Distribution of Rainfall
Nantou, located in central Taiwan, experiences a subtropical monsoon climate characterized by abundant precipitation throughout the year. The rainfall pattern exhibits distinct seasonal variations, with the wettest months occurring between May and September. During this period, the southwest monsoon brings warm, moist air from the ocean, resulting in frequent and heavy rainfall. The average monthly precipitation during these months ranges from 150 to over 300 mm.
In contrast, the winter months (December to February) are relatively dry due to the prevailing northeast monsoon. This wind direction brings colder and drier air from the Eurasian continent, leading to fewer precipitation events and lower monthly rainfall amounts ranging from 50 to 100 mm. The transitional months of March, April, and October receive moderate rainfall, typically between 100 and 150 mm per month.
Annual Rainfall Variation
The annual rainfall in Nantou varies significantly from year to year. This variability is primarily influenced by the strength and duration of the monsoon winds and the occurrence of tropical cyclones. In years with strong monsoons and frequent typhoons, the total annual precipitation can exceed 2,500 mm. However, in drier years, it may fall below 2,000 mm. Long-term rainfall data indicate that the average annual precipitation in Nantou is around 2,200 mm.
Snowfall in Nantou
Nantou, a mountainous county in central Taiwan, experiences occasional snowfall during the winter months. The highest mountain in Nantou, Hehuanshan, often receives a blanket of snow as temperatures drop below freezing. In recent years, snowfall has become increasingly common in Nantou, thanks to a combination of factors, including climate change and the rise of cold fronts from the north.
The snowfall in Nantou has significant implications for the local economy and infrastructure. The influx of tourists seeking to witness the rare sight of snow in Taiwan has boosted tourism revenue in the county. However, snowfall can also cause disruptions to transportation and power lines, particularly in remote mountainous areas. The local government has implemented measures to mitigate these risks, such as snow removal teams and emergency response plans.
Climate Patterns
Nantou, nestled in the mountainous heart of Taiwan, experiences a subtropical monsoon climate, characterized by abundant rainfall and warm temperatures year-round. The sun shines generously throughout the year, casting its golden rays upon the picturesque landscapes. However, the region’s subtropical location makes it prone to typhoons and heavy precipitation, particularly during the monsoon season in the summer months. During this period, rainfall can be intense, causing occasional flooding and landslides.
Seasonal Sun Exposure
The duration and intensity of sunlight vary depending on the season. In the summer months (June to August), the sun is at its peak, with an average of over 9 hours of daylight. The intense heat and high humidity make for sweltering conditions, with temperatures often exceeding 30°C (86°F). In contrast, the winter months (December to February) offer a milder climate with shorter daylight hours, averaging around 6 hours. The sun’s rays are less intense during this time, providing a more pleasant temperature range. The spring (March to May) and autumn (September to November) seasons offer a balance between sunshine and milder temperatures, making them ideal for outdoor activities.

Annual Humidity
Nantou, Taiwan experiences a humid subtropical climate characterized by high levels of humidity throughout the year. The average annual relative humidity hovers around 80%, with fluctuations occurring between seasons. During the hot and humid summer months (June to September), humidity levels soar, often exceeding 90%. In contrast, winter (December to February) brings slightly lower humidity levels, typically ranging from 75% to 85%. However, even during the drier months, humidity remains relatively high.
Seasonal Variations
Humidity levels in Nantou vary significantly based on the monsoon winds. During the summer months, the prevailing southwest monsoon carries warm, moist air from the ocean, contributing to the high humidity levels. Conversely, during winter, the northeast monsoon brings cooler, drier air, resulting in a slight decrease in humidity. As a result, summer nights in Nantou are often muggy, while winter evenings tend to be more comfortable. Additionally, humidity levels can fluctuate dramatically within a single day, particularly during the summer months. Sudden rainfall or thunderstorms can cause humidity levels to spike, creating a stifling atmosphere.
Seasonal Wind Patterns
Nantou, a county in central Taiwan, experiences distinct seasonal wind patterns. During the summer months, the prevailing wind is the southwest monsoon, which brings warm and humid air from the south. This wind is often accompanied by heavy rainfall, especially in the mountainous regions of Nantou. In contrast, during the winter months, the northeast monsoon dominates, bringing cooler and drier air from the north. This wind can be strong at times, especially in the coastal areas of the county.
Mountain-Valley Winds
Due to Nantou’s mountainous terrain, local wind patterns are also influenced by mountain-valley winds. During the day, when the air near the mountain slopes is heated by the sun, it rises, creating an upslope wind. This wind carries warm air up the slopes and into the valleys. At night, when the air cools, the downslope wind takes over, carrying cool air down the slopes and into the valleys. These mountain-valley winds can have a significant impact on local temperatures and precipitation patterns.
