中新网8月5日电 国家防灾减灾救灾委员会办公室、应急管理部5日举行汛期安全知识发布会。会 上，应急管理部新闻发言人、新闻宣传司司长申展利通报8月份全国自然灾害风险形势。申展利表示，8 月份，我国七大江河流域全面进入主汛期。华北、东北、华东、华南、西南部分地区洪涝和风雹灾害风 险高，海河流域、松辽流域部分河流可能发生较大洪水；预计有2到3个台风登陆或影响我国，1个台风 影响长江以北地区；大兴安岭、新疆北部、中南、西南局部地区森林火灾风险较高；云南西部局部地区 地质灾害风险高；长江中下游、江淮、新疆中北部局部地区存在高温干旱风险。 申展利指出，近年来，受全球气候变化影响，灾害性天气的突发性、极端性、不确定性愈加明显， 特别是进入汛期，突破历史纪录和传统认知的灾害频繁发生。当前，正处于"七下八上"防汛关键期，这 是一年中防汛形势最复杂、最严峻的时期。同时，暑期外出旅游、野外施工作业处于旺季，安全风险较 为突出。 ...

自7月23日以来，北方多地持续遭受强降水影响，内蒙古、河北北部、北京及太行山前区域成为强 降水核心区。"高温和强降雨多发、分散、影响范围大是近期全国天气形势的特点。"中央气象台首席预 报员张涛介绍，目前，一条西南至东北向雨带稳定维持在华北北部和东北中南部，给内蒙古东南部、河 北北部、北京、辽宁、吉林等地带来集中降雨。雨带目前正缓慢向南压且强度减弱，上述地区降雨强度 也将明显减弱。 截至7月26日，我国北方共有19个站点打破同期历史月极值，其中13个站点刷新历史极值。在此轮 降水过程期间，陕西北部、内蒙古、河北北部、北京等地累计降水量普遍超过100毫米，石家庄北部、 保定西部等区域累计降水量突破400毫米，充分展现此次过程的极端性。 近期，我国天气形势复杂多变，华北地区遭遇连续强降雨天气。目前正值"七下八上"防汛关键期， 全国呈现强降雨与大范围高温天气并存的典型汛期格局。本轮华北降水总体情况如何？未来发展趋势怎 样？公众又该如何有效防范？记者就此采访了相关专家。 未来三天，多雨、大范围高温仍是华北天气主要发展趋势。张涛表示，北方地区将会有两次降雨天 气过程，一是目前华北北部到东北中南部的雨带维持带来叠加降雨；二 ...

新华社北京7月29日电 连日来，北京遭遇连续极端强降雨，造成重大灾害。此次降雨有哪些特点？降雨是如何形成的？后续还有哪些需要注意的 情况？专家与相关部门为您一一解读。 降雨有何特点？ 降雨如何形成？ 漫长降雨如何形成？从宏观上看，西太平洋副热带高压是影响我国天气的关键系统，其季节性活动直接关系各地雨季进程。中国气象服务协会会 长许小峰介绍，从整体情况来看，目前正值"七下八上"防汛关键期，副热带高压稳定影响到华北地区，北京已进入强对流天气多发的多雨水时 段。 具体而言，近期北京降雨可分为两个时期。记者梳理北京市气象部门发布的信息，24日至27日期间的降雨，系受副热带高压影响产生。许小峰介 绍，这一时期北方恰有弱冷空气不断南下，与副热带高压边缘暖湿气流交汇，形成降雨带，也就是典型的华北雨季形势。而28日夜间至29日上午 的降雨则是因为受高空槽及台风外围水汽远距离输送影响产生，自西向东给北京带来了相对均匀的大面积降雨。 7月27日在北京市密云区冯家峪镇西庄子村拍摄的河道。新华社记者 鞠焕宗 摄 接下来如何防范？ 气象部门介绍，29日14时30分许，影响北京市的强降雨云团已移出。北京市气象台7月29日14时30分解除 ...

Core Viewpoint - The recent extreme rainfall in northern China, particularly in regions like Beijing and Hebei, has led to significant flooding and infrastructure damage, with the current weather patterns attributed to the seasonal "Seven Down, Eight Up" period, which is characterized by concentrated rainfall and severe weather events [1][3][6]. Summary by Sections Rainfall and Flooding Impact - From July 23 to 28, 41 rivers in Tianjin, Hebei, and Inner Mongolia experienced flooding above warning levels, with the maximum exceeding 2.39 meters [1] - Beijing's emergency response was activated on July 28 due to heavy rainfall, with predictions of over 150 mm of rain in most areas and localized amounts reaching 300 mm [3][4] - The extreme rainfall has caused landslides and damage to infrastructure, prompting rescue operations in affected areas [9] Meteorological Analysis - The current heavy rainfall is linked to a strong subtropical high-pressure system that has been stable and positioned north of 25°N, facilitating moisture transport to northern China [7] - The interaction of warm moist air with cold air fronts has resulted in significant precipitation events [7][9] - The geographical features, such as the Taihang Mountains, have enhanced rainfall through orographic effects, leading to localized extreme weather [9] Historical Context and Predictions - The onset of the rainy season in North China began on July 5, marking the earliest start since 1961, although the overall precipitation from March 15 to July 22 was 303.9 mm, which is 6.2% below the historical average [10] - Forecasts indicate that during the "Seven Down, Eight Up" period, regions including Inner Mongolia, Beijing, and parts of Northeast China may experience 20-50% more rainfall than usual, with potential for extreme weather events [10]
