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].

天气系统"乱成一锅粥"，成云致雨，让杭州被强对流"袭击"的概率变大。杭州市气象台预计，周五 仍有雷阵雨天气，不过不会覆盖全部地区，降雨云团往往如天女散花般分散在各处，能量却不一定弱， 雷雨时可能伴有短时暴雨和7-9级雷雨大风等强对流天气。在此提醒大家外出时记得带好雨具，做好防 御准备。 接下来，随着高压环流进一步分离，副高"势力"被分散，罩在头顶的"热锅"挪开，加上海上台风将 接二连三地发展，副高难以拿回杭州的"控制权"。在东风气流的影响下，之后杭州仍多雷阵雨，高温将 进一步削弱。今起，杭州的最高气温会在"高温线"徘徊，空气湿度大，闷热感加重。 为什么天气"说变脸就变脸"？其实，这都是"风"惹的祸。浙江省气象局宣传科普首席专家楼茂园解 释，从高空天气形势图来看，浙江上空呈典型的"鞍型场"分布，"东西有副热带高压和大陆高压，北面 （东北地区）有一个冷涡，南面菲律宾附近有一个热带低压在活动。"这样的形势让浙江上空吹来较冷 的偏北风，与近地面较热的偏南风"相遇"，便容易激发强对流，也就出现了周四下午的"一秒天黑"。 周四，杭州的天气舞台上演了"一出大戏"。主城区最高温达37.5℃，高温"冒头"，下午雷电、暴 雨、雷 ...
