台风“格美”预计将于7月31日移入吉林省，当地气象部门提醒民众需警惕降水叠加影响，当前吉林省已出现大范围中到大雨，部分地区暴雨或大暴雨，过程降水量超过100毫米。台风“格美”带来的降水与前期降水基本无缝衔接，加剧了当地水文条件的紧张状态，土壤含水量和水库河道的蓄水能力相对往年偏低，这使得降水叠加影响更为显著。
吉林省气象台台长陈长胜表示，台风“格美”正以每小时15公里至20公里的速度向北偏西方向移动，强度逐渐减弱。预计30日台风倒槽将到达吉林省，31日台风中心移入，届时将带来明显降水天气，并伴随短时强降水等强对流天气。从当前的天气形势图分析，台风“格美”与副热带高压之间形成了一个宽广且强势的水汽输送带，将大量水汽由南向北输送，这为吉林省带来了大量的降水条件。
陈长胜强调，由于本次台风体积较大，虽然中心移动至吉林时强度已经减弱，但仍能观察到一个相对完整的旋转环流。台风移动的前沿或右侧降水将偏强，而左端可能产生对流性降水，这也是台风北上降水时间持续较长的原因之一。
鉴于此，吉林省气象台已发布暴雨橙色预警，洪涝灾害气象风险预警、山洪气象灾害等预警也均升级为橙色，提醒相关部门和社会公众做好防御措施，加强安全防范，确保人员和财产安全。同时，也呼吁社会公众保持关注气象信息，及时采取应对措施，共同应对即将到来的台风影响。

News Title: Typhoon “Geme” Approaches Jilin, Local Authorities Alerted for Overlapping Rainfall Impact
Keywords: Typhoon Geme, Overlapping Rainfall, Jilin Warning
News Content: Typhoon “Geme” is forecasted to enter Jilin Province by July 31st, with the local meteorological department advising the public to be vigilant against the impact of overlapping rainfall. Currently, Jilin Province has experienced widespread moderate to heavy rain, with some areas experiencing torrential or extremely heavy rain, with precipitation exceeding 100 millimeters in some regions. The rainfall brought by Typhoon “Geme” is seamlessly connected to the previous rainfall, exacerbating the local hydrological conditions. The water content in the soil and the storage capacity of reservoirs and rivers are relatively lower than in previous years, making the impact of overlapping rainfall more pronounced.
Director Chen Changsheng of the Jilin Meteorological Observatory stated that Typhoon “Geme” is moving in a north-west direction at a speed of 15 to 20 kilometers per hour, with its intensity gradually diminishing. It is expected to reach Jilin Province by the 30th, and the typhoon center will move in on the 31st, bringing significant rainy weather accompanied by short-term heavy downpours and other strong convective weather. Analyzing the current weather pattern, the wide and powerful moisture transport channel formed between Typhoon “Geme” and the subtropical high-pressure system is delivering large amounts of moisture from south to north, providing substantial conditions for rainfall in Jilin Province.
Chen emphasized that despite the weakening of the typhoon when its center moves to Jilin, it is still possible to observe a relatively complete rotating circulation. The leading or right flank of the typhoon’s movement is likely to experience stronger rainfall, while the left end may generate convective rainfall. This is one of the reasons why the rainfall lasts longer as the typhoon moves northward.
Given this situation, the Jilin Meteorological Observatory has issued a severe rainstorm warning, with flood disaster meteorological risk and mountain torrential rain meteorological disaster warnings also elevated to severe. This is a reminder to relevant departments and the public to take preventive measures, strengthen safety precautions, and ensure the safety of personnel and property. It also calls on the public to stay informed about weather information and take timely actions to jointly cope with the upcoming typhoon impact.
