本周上海主打阵雨雷雨，前半周，上海高温多，加速水汽蒸发，水汽凝结成云释放能量，加剧空气 的上升运动，为雷暴、暴雨等强对流提供动力。后半周，上海位于副热带高压边缘，容易触发或增强降 水。 记者 戚颖璞 上海中心气象台预报，今天至周三，天气基本保持"35℃+午后短时阵雨或雷阵雨"的配置。今天最 高气温35℃，北部地区有降水回波活动，出现较为明显的短时降水。 台风影响结束，高温无缝衔接，上海的盛夏回来了。 ...

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 ...
