阴天 (yīn tiān) vs 多云 (duō yún): use 多云 when there are clouds but some sun may still be visible, while 阴天 indicates overcast conditions with no sunlight.

Think of 多 (duō) as 'many' and 云 (yún) as 'clouds'. Imagine a sky filled with many clouds, blocking the sun. This can help you remember that 多云 means 'cloudy' and pronounce it as 'duo yun' with a duo of clouds up high.

多云 is typically used in weather reports and is considered neutral in register, suitable for both formal and informal contexts. Be mindful of tone; the first syllable (duō) is pronounced with a high level tone, while the second syllable (yún) has a rising tone. Common collocations include 多云天气 (duō yún tiān qì) meaning 'cloudy weather'.

多云 is relevant for HSK Level 2 learners, connecting with other weather-related vocabulary like 晴天 (qíng tiān, sunny day) and 下雨 (xià yǔ, to rain). Focus on recognizing and using it within the context of weather and daily conversations.

In Chinese culture, weather plays an important role in agricultural practices and daily life. The term 多云 may be used when discussing seasonal changes and their impact on farming, reflecting the agrarian roots of many communities.

Learners often confuse 多云 with 阴天 (yīn tiān), which means 'overcast' or 'gloomy' but indicates a different weather condition. Remember, 多云 means there are many clouds, not necessarily a lack of light.
