一 | 第20号台风生成，海上“三台共舞” 今天，我们迎来24节气中的第14个节气处暑。进入处暑，通常三伏天已过或接近尾声，今年比较巧，刚好是三伏的最后一天，明天就是出伏的日子。往年这个时候，杭州暑热并未完全消退，最高气温都在30℃以上，甚至出现35℃以上的高温天气。这几天因为下雨的原因，气温不算太高，并未触及高温线，杭州市气象台说，今天我市仍有较明显降雨过程，局部雨量可达大雨级别，最高气温大约在33℃。

A Chinese delegation proposed establishing an International Grassland Day at the 17th Session of the Conference of the Parties (COP17) to the United Nations Convention to Combat Desertification (UNCCD), which opened in Ulan Bator of Mongolia on Monday. China also pledged to share its expertise and experience in combating desertification with other countries during the event.
China shared its experience in science-based desertification control, grassland restoration, technological innovation and livelihood development at the event, while highlighting regional achievements under China-Arab States, China-Mongolia and China-Central Asia cooperation mechanisms on desertification control, the Global Times learned from China's National Forestry and Grassland Administration (NFGA).
China has contributed about 25 percent of the world's newly added green areas and taken the lead in achieving zero growth in land degradation.
Held under the theme "Restoring Land, Restoring Hope," COP17 brings together representatives from 197 parties, as well as UN agencies, international organizations, research institutions and businesses, to discuss issues including the restoration of degraded land, sustainable land management, drought resilience and grassland conservation.
The conference will also feature plenary sessions, implementation review meetings and high-level ministerial dialogues, with a focus on innovative financing, drought resilience, grassland restoration and pastoralists' well-being. Interactive forums on water resources, food systems and other topics will also be held.
Hosting COP17 in Ulan Bator is expected to place an international spotlight on Mongolia's land restoration priorities, including approaches that safeguard livelihoods, strengthen food security and protect ecosystems in dryland regions.
The conference is also taking place during the United Nations International Year of Rangelands and Pastoralists 2026 (IYRP 2026), declared by the UN General Assembly and championed by Mongolia. The year provides an important opportunity to advance the sustainable management, restoration and conservation of rangelands and to highlight the needs of pastoralist communities whose livelihoods depend directly on these ecosystems, according to Xinhua News Agency.
Desertified land accounts for about one-quarter of China's total land area. After more than half a century of sustained efforts, China has achieved a historic shift from "advancing sands and retreating people" to "expanding greenery and retreating deserts," with both desertified and sandy land areas continuing to decline, according to the NFGA.

China has become the first country in the world to achieve zero growth in land degradation, with 53 percent of its treatable sandy land effectively restored.
Over the past five years, China has completed 36.6 million hectares of land greening, raising its forest coverage rate to more than 25 percent and contributing about 25 percent of the world's newly added green areas, statistics from the NFGA show.
Moreover, China attaches great importance to international cooperation on desertification control. It has established the China-Mongolia Desertification Prevention and Control Cooperation Center, the China-Arab International Research Center for Drought, Desertification, and Land Degradation, and the China-Central Asia Desertification Prevention and Control Cooperation Center, providing Chinese solutions and expertise to the global fight against desertification, according to China's National Forestry and Grassland Administration.
For example, hundreds of wells drilled by Chinese teams have turned sandy areas into farmland in Egypt, supporting desert reclamation. China has supplied drought-resistant saplings to Mongolia's "Billion Trees" campaign. Africa's own "Great Green Wall" initiative, inspired by China's National Forestry and Grassland Administration, has also gained support from China, Xinhua reported last year.
。明天开始雨水逐渐减弱，以午后分散性阵雨或雷雨为主。虽然和之前的高温天相比，现在的气温已经缓和了许多，但叠加高湿度，闷热感难免，同样要注意防暑。进入8月后，海上的动静几乎没停过。目前有三个台风在活动，天气形势越发复杂，提醒大家随时关注相关信息。台风“简拉维”将给浙江带来风雨昨天，今年第20号台风“简拉维”生成，海上进入“三台共舞”时段（另外两个是第18号台风“沙德尔”和第19号台风“紫檀”）。

二 | 对浙江影响最大的是最新生成的“简拉维”。据中央气象台，“简拉维”（热带风暴级；英文名称：Gaenari）于昨天下午在西北太平洋洋面上生成，浙江省气象服务中心预计，“简拉维”将以每小时5~10公里的速度向偏西方向缓慢移动，逐渐向浙闽沿海靠近，强度变化不大（或逐渐减弱）。受“简拉维”影响，昨天夜里沿海和浙南地区有阵雨或雷雨，局部暴雨。

三 | 23日—25日雨势增大，东南沿海和浙南部分地区有大雨暴雨，局地大暴雨。除了雨还有大风，昨天下午至24日夜里东海中南部部分海域有8~10级局部11级阵风；昨天夜里至25日沿海海面和杭州湾水域有8~10级阵风，建议沿海渔场、海上养殖、渔业捕捞、滨海旅游等做好大风防范。浙江省气象服务中心提醒，此次台风影响下，东南沿海累计雨量大，并与前期强降雨区重叠，暴雨致灾风险较高，需重点防范可能引发的地质灾害、小流域山洪、城乡积涝等次生灾害。因第20号台风“简拉维”对浙江地区的影响，为确保铁路运输和旅客出行安全，铁路部门计划对8月23日途经杭深铁路G7667次等列车、杭台高铁G7713次等列车，采取临时停运、缩短区段和限速运行等措施。下一步，铁路部门将密切关注台风天气变化，根据风速、雨量和影响程度等实际情况，动态调整列车开行方案，保障旅客安全出行需要。具体列车开行信息，请关注车站公告或致电铁路12306客服热线查询，以便妥善安排行程。“沙德尔”可能升级为超强台风对我国影响较大的还有19号台风“紫檀”。昨天18时，“紫檀”中心位于距离广西东兴市东南方向约65公里的北部湾上，强度为热带风暴级，中心附近最大风力为8级（18米/秒），中心气压992百帕，七级风圈半径100~150公里。预计“紫檀”将原地少动，强度逐渐增强。

四 | 气象专家提醒，“紫檀”将在北部湾海面长时间滞留，海南、广西、广东、福建等地将有持续性强降雨天气，部分地区累计雨量有一定极端性，需做好提前防御工作。生成最早的18号台风“沙德尔”目前离我们最远。“沙德尔”昨天14时位于我省东南方向约2800公里的西北太平洋洋面上，当时强度还是台风级，中心位置最大风力13级（40米/秒），最低气压960百帕。15时中央气象台发布的台风快讯显示，它已经成为强台风级，中心附近风力也达到了14级（42米/秒）。
