Group 1 - The weather in Hangzhou has been characterized by a surprising appearance of rainbows due to rich low-level moisture, creating a pleasant atmosphere despite temperatures reaching a maximum of 34.8°C, which is below the high-temperature threshold [1] - The upcoming weather forecast indicates that Hangzhou will continue to experience relatively low temperatures, with maximum temperatures expected to remain below 35°C, particularly over the weekend [1] - There is a potential for short-term heavy rainfall, and residents are advised to carry rain gear and be cautious of localized flooding [1] Group 2 - Data shows that the number of high-temperature days this year is significantly higher than in previous years, with a total of 20 high-temperature days recorded so far, compared to the average of 12 days [2] - The perception of a milder summer is attributed to the earlier departure of the plum rain season, which has shifted concentrated high-temperature weather to earlier in the season, while recent influences from typhoons and easterly airflows have kept temperatures in check [2] - The forecast suggests that the current unusual weather pattern, with the absence of the subtropical high and the frequent occurrence of typhoons, may prevent temperatures from rising significantly in the near future [2]

央视网消息：台风"韦帕"未来对我国的风雨影响范围有多大？一起来了解。 中国气象局气象分析师周丽贤称："7月20日，台风'韦帕'沿着粤西沿海一路西行，给华南多地制造了狂风暴雨。21日，它将在北部湾内继 续向西偏南方向移动，强度还将略有加强。21日依然是它影响我们国家最主要的时段。风最大的地方主要是在北部湾，台风中心的最大风力可 达12~13级。同时在广西沿海、广东西部沿海以及海南岛沿海风也不小，普遍有8~9级，阵风可达10~11级，建议大家要尽量避免户外活动。21 日雨最大的地方集中在广西南部、海南岛的西部，这里普遍是暴雨、大暴雨，局地甚至有特大暴雨的天气。而广东处于台风'韦帕'的东侧，在 偏南气流的影响之下，21日也会有一些分散的强降雨天气。与此同时，'韦帕'的环流非常大，在它的外围环流和副热带环流的共同作用之下， 21日福建还有浙江等地也会有一些强降雨。建议大家在雨大的时候，要远离像地下通道以及地下停车场等容易积水的区域。22日，'韦帕'对于 我们国家的影响会逐渐减小，尤其是'韦帕'在越南北部再次登陆之后，对于我们国家的影响会明显减小。像北海，22日白天的风力可达7~8 级，但是到晚上就会减弱到3~4级。预 ...

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 ...

Core Viewpoint - The upcoming summer heat during the Sanfu period is expected to be intense, with predictions of extreme weather events, including both droughts and floods, particularly in eastern China [2][4]. Group 1: Weather Predictions - The National Climate Center forecasts an increase in extreme weather events during this period, with a notable distribution pattern of rainfall being more abundant in the north and less in the middle regions [2]. - Jiangsu Provincial Climate Center predicts that the Sanfu period will be characterized by high temperatures, with the onset of high heat becoming increasingly delayed into late summer [2][4].
