本周杭州晴雨交替频繁超强台风“沙德尔”或直奔东南沿海_我的网站

主君的太阳

A | 昨天，秋天的第二个节气——处暑如约而至。

B | A powerful Monday morning earthquake has killed at least 111 and injured 87 in the west part of Colombia. Colombia's President Abelardo de la Espriella, who came to office just three days before the earthquake, declared a state of emergency to expedite funding for the quake recovery with a plan to visit the disaster zone. "I am at the forefront of the situation. It pains me deeply what the families and affected regions are going through," he posted on X. According to information provided by Colombian officials by mid-afternoon, the destruction included 1,575 damaged homes, 37 homes completely destroyed, 61 collapsed buildings, scores of damaged centers of health, education and community, as well as 18 damaged roads and six airports. Airports in Pereira, Manizales, Quibdo, Armenia, Cartago and Buenaventura suffered structural damage, and their flight operations were suspended, according to Colombia's Civil Aviation Authority. The tremor was felt in Colombia's capital Bogota, which is about 400 kilometers from the epicenter, setting off alarms that prompted people to evacuate many buildings as a precaution. "At this time there are no reports of injuries or structural damage, only some cracks in buildings," Bogota Mayor Carlos Galan posted on X. The earthquake damaged the region's major cities including Pereira, Quibdo, Manizales and Cali. Nubia Carolina Cordoba-Curi, governor of the Choco region, posted on X on Monday morning that "in the capital Quibdo there are injuries and severe damage to buildings". She posted an update at 2 pm that 12 people were confirmed dead and 84 injured in Choco. Other local authorities reported at least 40 deaths in the Risaralda region and 27 deaths in the Valle del Cauca region. Rescue efforts to save people buried under the debris is ongoing. According to the Colombia Geological Service, the earthquake epicenter was in San Jose del Palmar, Choco. It had a magnitude of 7.4 and a depth of approximately 103 km, making it the strongest earthquake recorded in Colombia in the last decade. The earthquake was felt by neighboring countries Venezuela, Ecuador and Panama. It was followed by several aftershocks with magnitudes between 2.8 and 4.8, according to the agency. The agency said that it's common for this region to experience earthquakes of considerable magnitudes due to activities associated with the subduction of the Nazca Plate beneath the South American Plate. Near the end of June, Venezuela was struck by two earthquakes — with magnitudes of 7.2 and 7.5 — that were only 39 seconds apart. More than 6,000 people were killed, and tens of thousands of people remain missing under the debris. 。“处，止也，暑气至此而止矣。”处暑的到来，意味着暑气开始消退，酷热难熬的天气接近尾声。不过，对于杭州来说，当前副热带高压“余威”尚存，昨天主城区最高温仍有32.8℃、余杭区则跃上35.3℃，闷热不减。

C | 接下来，天气舞台上还有“捣蛋鬼”动作频频，本周“天气大戏”即将开演。

D | 处暑至闷热不减杭州开启晴雨交替模式当前，虽然暑热最盛阶段已过，但副热带高压仍“不甘示弱”，持续发威。

E | 据杭州市气象台消息，由于副高再度回归，杭州天气转为多云为主，出太阳的时间逐渐增多。不过，这段时间副热带高压的实力并不强，高压环流浅薄，无法彻底阻断低层水汽输送，在午后气温较高的时段，容易引发降雨甚至强对流，午后有分散性阵雨或雷雨的天气模式将持续到本周四（27日）。处暑期间，往往台风活跃。

F | 当前，西北太平洋和南海海域正上演着“三台共舞”——今年第18号台风“沙德尔”、第19号台风“紫檀”和第20号台风“简拉维”同时活跃。对浙江来说，上周日，“简拉维”和“紫檀”两个台风的环流，形成双涡轮的水汽传送带，上演了“急雨倾盆”的戏码。今明两天，强降雨“主战场”仍锁定在浙南地区，部分地区雨势持续强劲。

G | 据浙江天气网消息，今天东南沿海和浙南地区雨势较强，部分暴雨，局部大暴雨；明天主攻浙南沿海，依旧部分暴雨，局部大暴雨。

H | 有雷雨地区局部还可能伴有短时强降水，雨势汹汹。

I | 在此提醒大家，近期晴雨交替频繁，洗晒衣物建议优先选择室内晾晒，日常外出记得随身携带雨具，及时关注当地预警信息，防范突发降雨。超强台风“沙德尔”或奔向东南沿海为什么今年的台风这么多？当前，远在西北太平洋还有一个超强台风“沙德尔”不容小觑。中国天气网显示，昨天上午，“沙德尔”已升级为超强台风，从卫星云图来看，“沙德尔”环流庞大，直径约1000公里，结构对称、眼区清晰，对流旺盛。预计周二（25日）前“沙德尔”对我国无影响，但后期路径存在较大变数，不排除登陆我国东南沿海的可能性。“沙德尔”会不会影响杭州？市气象台预计，其走势完全取决于副热带高压的强弱，高压强势则台风南压、对杭州影响较小，高压减弱则台风北调，或将影响杭州周四（27日）后的天气走势。值得注意的是，无论“沙德尔”未来怎么走，都将给我国带来明显的风雨影响，浙江天气网预计周四至周六（27日—29日），受其外围影响，沿海地区将再次迎来中到大雨、局部暴雨。另外，西北太平洋上还有一个热带低压正在活动。

J | 中央气象台首席预报员张玲表示，这个热带低压存在成为下一个编号的台风的可能，并且在“沙德尔”逐渐靠近我国的过程中，它可能与台风“沙德尔”产生互旋，并为台风“沙德尔”提供更多水汽，成为影响台风“沙德尔”进入东海后的路径和强度的重要因素之一。若其正式生成，海面上将出现“四台共舞”的现象。

K | 中国天气网数据显示，今年1月至8月，每个月都有台风生成，且数量均多于常年同期。常年1月至8月平均生成13.4个台风，而今年8月尚未结束，生成总数已达20个，较历史同期偏多8个。为什么今年的台风这么多？“这与当前的厄尔尼诺状态密切相关。”张玲解释，在厄尔尼诺背景下，容易导致大西洋飓风生成受到抑制、个数偏少，但西太平洋的台风活动则会更加活跃。从目前台风生成个数来看，符合厄尔尼诺年的台风活动特点。目前，三个台风对我国华东和华南地区的影响是一个连续过程，无明显间歇期，未来需警惕持续强降雨引发的次生灾害及风雨叠加效应，同时“沙德尔”将正面影响我国华东沿海地区，强度较强、致灾风险高，需密切关注“沙德尔”的路径变化。
