Group 1 - The clear blue sky in Hangzhou on August 28 is attributed to the strong subtropical high pressure, which prevents moisture from rising and forming clouds [2] - The subtropical high pressure leads to a significant increase in temperature, enhancing the air's capacity to hold moisture, resulting in a cloudless sky [2] - Hangzhou has experienced a record-breaking 26 consecutive days of high temperatures from August 3 to 28, marking the highest number of hot days in August's history [2] Group 2 - The weather pattern is expected to remain hot and sunny under the influence of the subtropical high pressure, but a weakening of this system is anticipated starting August 31 due to the impact of a westerly trough [2] - After September 1, the intensity of high temperatures is projected to decrease, with maximum temperatures dropping to between 35°C and 37°C [2] - Residents are advised to take precautions against heat and potential severe weather, including localized heavy rainfall and thunderstorms [2]
