Core Points - The end of the "Sanfu" period this year is marked as a "short Sanfu," concluding 30 days earlier than the previous years, with an early end by 5 days compared to last year, 1 day compared to the year before, and 6 days compared to the year before that [1] - The "Sanfu" period consists of three phases: the initial phase, the middle phase, and the final phase, with the initial and final phases fixed at 10 days each, while the middle phase can vary between 10 to 20 days [1] - The determination of the duration of "Sanfu" is based on the ancient Chinese calendar system, specifically the "Geng" days following the summer solstice and the first "Geng" day after the beginning of autumn [1][3] - The current "Sanfu" period breaks a 10-year streak of 40-day durations from 2015 to 2024, initiating a new cycle of alternating 30 and 40-day durations from 2025 to 2036 [3] - Weather conditions post "Sanfu" are characterized by a gradual temperature decline, but the "autumn tiger" phenomenon may still persist, indicating a slow transition from summer heat [5]

Weather Conditions - The current weather in Zhejiang is influenced by the strengthening of the subtropical high pressure, leading to increasingly high temperatures, with some areas like Chuzhou and Lishui expected to reach 40°C to 41°C [1][3] - The Zhejiang Meteorological Observatory has issued high-temperature reports, predicting maximum temperatures of 35-38°C across most regions, with some areas exceeding 39°C [3][6] Forecast - The weather forecast for the upcoming week indicates a pattern of sunny to partly cloudy conditions with localized thunderstorms in the afternoons [4][8] - Specific forecasts include: - August 9: Partly cloudy with possible thunderstorms in northern Zhejiang [7] - August 10-12: Generally sunny to partly cloudy with afternoon thunderstorms [8] - August 13-15: Coastal areas may experience occasional rain or thunderstorms, while other regions remain mostly sunny [9] Health Recommendations - Due to the rapid rise in temperatures, there is a warning for potential strong convective weather in the afternoons, which may include short-term heavy rain and strong winds [5][11] - Health advisories suggest continuing heat prevention measures, such as reducing outdoor activities during peak heat hours and staying hydrated [6][15]

Core Viewpoint - The arrival of the "Autumn Tiger" signifies a continuation of high temperatures and humidity, despite the onset of the autumn season [1] Weather Forecast - The main precipitation in Suzhou is expected from the night of August 9 to the daytime of August 10, with other periods characterized by cloud changes and localized afternoon thunderstorms [1] - Early in the week, temperatures are predicted to be high, but will decrease later due to rainfall [1] - The current weather conditions are still influenced by the subtropical high pressure, leading to poor conditions for afternoon thunderstorms and persistent heat [1] - A rainfall event is anticipated from Saturday night to Sunday daytime, which will help lower temperatures [1] - The overall weather will remain humid and hot, with citizens advised to remain vigilant against heat [1]
