Core Points - The arrival of the Frost Descent solar term marks the end of autumn and the beginning of winter in China, with significant temperature fluctuations expected [1] - Cold air is forecasted to impact northern regions from October 25 to 27, bringing temperature drops and strong winds [2] Weather Conditions - The Frost Descent period is characterized by the largest temperature differences between day and night, with initial frost already observed in several regions before the solar term [1] - Areas such as Hebei, Shandong, Shanxi, and Henan are expected to experience initial frost during the Frost Descent [1] - Rain and snow are primarily affecting the eastern part of the Tibetan Plateau, with forecasts of light to moderate snow in several provinces [1] Temperature Changes - The strongest cold air mass of the second half of the year has already caused temperatures to drop to levels typical of November and December across much of the country [2] - Specific regions, including Inner Mongolia and Northeast China, are expected to see temperature drops of 4°C to 6°C, with local areas experiencing drops exceeding 8°C [2]

Core Viewpoint - The recent significant drop in temperatures across Shandong province is attributed to the influence of cold air masses, marking a shift from previous weather patterns characterized by persistent rainfall to a drier and colder climate [2][3]. Summary by Sections Current Weather Conditions - Shandong province has experienced a dramatic decline in temperatures, with the lowest recorded temperature at -0.2℃ on October 21, marking a new low for the second half of the year [2]. - The average temperature for October in Shandong is typically around 15.2℃, but current temperatures have fallen below this average, approaching the climate levels expected in November [2]. Causes of Temperature Drop - The primary reason for the ongoing low temperatures is the intensified cold air activity from Siberia, which has been able to penetrate the province due to the retreat of the subtropical high pressure [3]. - This cold air has not only caused a drop in temperatures but has also led to a shift from a "wet cold" to a "dry cold" climate, resulting in clearer skies as moisture is dispersed [3]. Short-term Weather Forecast - A gradual warming trend is expected from October 22 to 24, although the increase in temperatures will be slow [3]. - Following this brief warming period, a weak cold air mass is anticipated to bring light rain and a subsequent drop in temperatures around October 25 to 26 [3]. Long-term Weather Predictions - For November, the average temperature is projected to be between 7.5℃ and 8.5℃, slightly above the normal average of 7.5℃, with precipitation expected to be 20-50% lower than usual [4]. - The winter of 2025 is forecasted to have an average temperature of 1.0℃ to 2.0℃, which is also above the normal average of 0.6℃, with overall precipitation expected to be lower than average [4].
