西部地区冬春季节雨雪稀少，所以在冬春季开展增雪作业是一项重要的抗旱减灾措施。由于冬、春2季降水天气过程少，为了弥补冬春季飞机、火箭作业费用较高的不足，开发出新型延时自动点火焰弹。它是利用气球将焰弹携带到云层中，通过自动点火使焰弹在云中燃烧后产生的冰核催化来增加降雪量。试验表明：与同类产品相比，新型延时自动点火焰弹通过科学定时装置能够控制最佳作业时机，具有成本低、机动灵活性高、催化效果好、科学安全等特点，能够提高人工增雪的科技水平。

There is a little of rain and snow in winter and spring at Gansu Province ,therefore artificial snowfall enhancement in the two seasons is a significant measure to fight against natural disasters.Due to less precipitation in winter and spring ,if we use aircraft and rockets to enhance the precipitation,it will cost too much.As a result,using pyrotechnic flares carried by balloons is a good supplement of working by aircraft and rockets.The pyrotechnic flare igniting when the balloon carries it rising up to the clouds.When the pyrotechnic flares burning ,the ice nucleus formed at the same time,this process enhances the snowfall.The new delayed auto-ignition pyrotechnic flare can grasp the best working opportunity ,so that it can make the artificial snowfall enhancement more directly ,scientifically and safely.
