Winter in Jinan, the capital city of Shandong Province in eastern China, primarily focuses on cold temperatures and dry conditions. The winter season, which typically spans from December to February, is characterized by low humidity and minimal precipitation, making it a relatively dry and chilly period.

The reason for this focus on cold temperatures and dry conditions lies in Jinan's geographical location and the influence of the monsoon system. Jinan is situated in the temperate zone, where the winter monsoon brings cold, dry air from Siberia. This results in a significant drop in temperatures, often below freezing, and a lack of moisture. According to data from the National Meteorological Center, the average temperature in Jinan during the winter months ranges from 0°C to 5°C, with the lowest recorded temperature reaching as low as -18°C.

Moreover, the city's proximity to the Yellow Sea contributes to its dry winter climate. The sea's moderating effect on temperatures is minimal during the winter, as the sea is also cold and does not provide much moisture. This lack of humidity exacerbates the dryness and coldness of the winter season in Jinan.

The dry conditions are further compounded by the absence of significant precipitation during the winter months. The city receives only a small amount of snowfall, and the majority of the precipitation occurs in the form of light rain or drizzle. This lack of moisture can lead to discomfort for residents, who may experience dry skin and respiratory issues.

In conclusion, winter in Jinan focuses on cold temperatures and dry conditions due to its geographical location and the influence of the winter monsoon. The city's proximity to the Yellow Sea and the absence of significant precipitation contribute to the dryness and coldness of the winter season. Data from the National Meteorological Center supports the average winter temperature range of 0°C to 5°C, with occasional drops below freezing.
