Rain enhancement is the main activity field of weather modification in the countries that suffer from water stress. The charged aerosol is a new man-made condensation nucleus to enhance the water vapor condensation. In this article, the negative-polarity air plasma jet array with plasma volume larger than 2 cm ³ was used to generate the charged aerosols. Aerosols are mainly charged in the unipolar atmosphere. The averaged charge number of charged aerosols was measured to be 5818e. The attractive electric force of charged aerosols was more than ten times higher than the sum of thermophoretic forces and diffusophoretic forces. These charged aerosols accelerated the collision–coalescence process inside the cloud chamber, generated large droplets in the range of 40– $70~\mu \text{m}$ , and increased the settling amount of moisture by 58.8%.

负空气等离子射流阵列增强的水蒸气冷凝

在遭受缺水压力的国家，增雨是气候变化的主要活动领域。带电的气溶胶是一种新的人造凝结核，可增强水蒸气的凝结。在本文中，使用等离子体体积大于2 cm ³的负极空气等离子体射流阵列 来生成带电气溶胶。气溶胶主要在单极性大气中带电。带电气雾剂的平均电荷数经测量为5818e。带电气雾剂的吸引力比热泳力和扩散热力之和高十倍以上。这些带电的气溶胶加速了云室内的碰撞-凝聚过程，产生了40- $ 70〜\ mu \ text {m} $ ，使水分的沉降量增加了58.8％。
