从天气形势来看，虽然近期高温在线，但强度总体不如月初，这是为什么？市气象台解释，其实， 这几天虽然热，但杭州并不在副高控制之下，高温完全是靠阳光这把"火"给"烧"出来的。周三的高温橙 色预警也是因为近来连续的晴热天气导致地表热量累积，同时副热带高压范围略微扩张、杭州上空西北 风力减弱。 这几天，高温肆无忌惮，杭城持续处于"烧烤模式"。周三，杭州市气象台发布高温橙色预警信号， 主城区最高气温达36.5℃，"热"力四射。好在，这轮高温不打"持久战"，转折在即，周四起雨水上线。 值得注意的是，虽然未来一段时间高温并不凶猛，但体感也达不到"凉爽"的程度。尤其是，偏东气 流以及雨水会使空气湿度增加，体感变得潮湿闷热，不利于体表排汗，警惕可能引发中暑等一系列疾 病。 高温消退，接下来的天气重点可能要转向台风。据中央气象台消息，菲律宾以东热带低压已于周三 下午2点钟生成，预计该低压将以每小时15-20公里的速度向西偏北方向移动，强度逐渐增强，将于24小 时内加强为今年第6号台风"韦帕"，19日下午移入南海东北部海面，强度继续加强，最强可达台风级或 强台风级（13-14级，38-45米/秒），并逐渐向海南岛东部到广东中西部一 ...
