Due to the ongoing impact of the strongest heatwave since the beginning of 2025, a high-temperature orange alert was issued in Yuncheng, Shanxi, on July 5, with temperatures reaching up to 39°C.

To alleviate the effects of the heat on residents’ daily lives, the Tianmao Guobinfu residential community in Yuncheng has creatively adopted an “artificial rainfall” system. By spraying mist from the tops of high-rise buildings at scheduled times, the system helps lower local temperatures and improve the living environment.

The property management has installed multiple nozzles on rooftops, using high-pressure pumps to deliver water to the nozzles, forming a fine curtain of mist. This system is similar to the cooling mist devices used in gardens.

According to staff, the cost of the misting system is covered by the property fees, and the spraying schedule can be adjusted based on weather conditions and residents' needs. The mist falls from above, covering the community’s public areas like rain, effectively lowering local temperatures and improving comfort during the hot weather. Residents expressed high satisfaction, saying it felt “cool like a waterfall.”

受2025年以来最强高温过程持续影响，7月5日，山西运城发布高温橙色预警，最高气温达39℃。

为缓解高温对居民生活的影响，运城市天茂国宾府小区创新采用人工降雨模式，通过从高楼顶部定时喷洒水雾降低局部温度，改善居住环境。

该小区物业在楼顶安装了多个喷头，通过高压水泵将水输送至喷头，形成细密的水帘，这种系统类似于园林中的喷雾降温装置。

小区物业工作人员表示，该喷淋系统的费用纳入物业费，喷淋时间上可根据天气和居民需求进行调整。水雾从高处洒落，覆盖小区公共区域，像下雨一样降低局部温度，提升了居民高温天气下的生活舒适度，业主们都表示很满意，“像瀑布一样凉快”。
