Group 1 - The high temperature in Hangzhou reached 39.3℃, making it the highest in the province and the second highest in the country on August 21 [1] - The weather conditions included not only high temperatures but also strong convective weather, with multiple weather warnings issued for thunderstorms and heavy rain in various districts [1] - The forecast indicates that the high temperatures will persist, with maximum temperatures remaining between 37℃ and 39℃ for the upcoming week, and the perceived temperature may exceed 40℃ [1] Group 2 - Although artificial rain is not expected, localized thunderstorms are likely to occur in the coming days, providing brief and uneven rainfall in Hangzhou [2] - Typhoon "Lingling" formed on August 21 and made landfall in Japan, but it is not expected to alleviate the high temperatures in the region [2]

Summary of Key Points Core Viewpoint - The article discusses the weather conditions in Shanghai, highlighting the transition from typhoon effects to high temperatures, with forecasts indicating continued high temperatures and potential thunderstorms in the coming days [1]. Weather Forecast - Shanghai is expected to experience temperatures around 35°C from today until Wednesday, with afternoon short-term rain or thunderstorms [1]. - The highest temperature today is forecasted to reach 35°C, with northern areas experiencing notable short-term precipitation [1]. Weather Dynamics - The first half of the week will see high temperatures in Shanghai, which will accelerate water vapor evaporation, leading to cloud formation and energy release, thus enhancing the potential for thunderstorms and heavy rain [1]. - In the latter half of the week, Shanghai will be positioned at the edge of the subtropical high pressure, making it susceptible to triggering or intensifying precipitation [1].

Group 1 - The weather in Hangzhou experienced a dramatic shift with a maximum temperature of 37.5°C followed by thunderstorms and heavy rain due to a clash of cold and warm air masses [1] - The Zhejiang Meteorological Bureau explained that the weather pattern was influenced by a typical "bowl-shaped" distribution of high and low pressures, leading to increased chances of strong convective weather [1] - The forecast indicates that thunderstorms will continue in Hangzhou, with potential for short-term heavy rain and strong winds [1] Group 2 - The influence of high-pressure systems is diminishing, leading to a decrease in high temperatures and increased humidity in Hangzhou [2] - The development of Typhoon "Wipha" is expected to impact the region, with potential for multiple typhoons to approach the coast [2] - The forecast suggests that the next typhoon may target areas including Taiwan, Fujian, and Zhejiang, although the timing remains uncertain [2]
