"目前来看，副热带高压要到8月底才会明显南退，整个8月下旬浙江还是以热为主，早晚气温也不 低。不过，白天温度高、近地面气流上升，海洋气流会有补充，傍晚或有些海陆风。"浙江省气象局宣 传科普首席专家楼茂园补充道。 按照以往来说，"出伏"标志着伏天结束，暑热逐渐消退、天气开始转凉，但今年的天气却很是"反 常"，"出伏"反而像"入伏"，这是为什么？市气象台解释，由于副热带高压的"强势"，在其控制下，晴 热高温天气持续，甚至愈演愈烈。周三周四两天杭州最高气温甚至直冲40℃，除了白天暑热，夜间闷热 也不下线，最低气温直逼30℃，全天候暑热袭扰。 周二是"出伏"的第一天，但高温却丝毫没有"歇业"的意思，杭州市气象台发布了今年8月以来首个 高温橙色预警信号，主城区最高气温达38.9℃创今年入夏以来新高，余杭区更是跃上40.5℃，酷热难 耐。接下来，"火辣辣"的暑热感还会持续，高温强度直至近期巅峰。 短期内高温并不会结束。其实，8月以来，杭州连续高温日已达到17天，本周高温会继续保持"全 勤"，若下周高温持续或打破2022年创下的8月最长连续高温纪录。 如此漫长又"凶悍"的高温期，会不会有"降温利器"前来灭灭火？这还得看天气 ...
