The possibility of creating artificial clouds based on theoretical modeling of a vertically directed buoyancy jet was analyzed considering vertical temperature lapse rate, wind speed, relative humidity of the near-ground atmospheric layer, and thickness of the inversion layer. Numerical experiments demonstrated that a jet with an initial velocity of 300 m/s, the temperature of 300 °C, and flow volume of 240 m3/s without additional energy feeding can reach the condensation level in certain conditions, namely, absence of an inversion layer, vertical temperature lapse rate >8 °C/km, and humidity >85%. The introduction of three types of hygroscopic aerosols with different hygroscopic points into the jet and the replenishment of the jet energy with heat from the condensation of water vapor can expand the boundaries of favorable conditions for stimulating thermal convection and creating artificial clouds. The results can be used to develop criteria for choosing days with favorable conditions for conducting field experiments.

有利于通过吸湿气溶胶饱和射流产生人造云的大气条件

考虑垂直温度直减率、风速、近地层大气相对湿度和逆温层厚度,分析了基于垂直定向浮力射流理论模型创建人造云的可能性。数值实验表明,射流的初速度为 300 m/s,温度为 300 °C,流量为 240 m 3/s 在没有逆温层、垂直温度递减率 >8 °C/km、湿度 >85% 的特定条件下可以达到冷凝水平。将三种不同吸湿点的吸湿气溶胶引入射流,并利用水蒸气冷凝产生的热量补充射流能量,可以扩大刺激热对流和形成人造云的有利条件边界。结果可用于制定标准,以选择具有有利条件的日子进行现场实验。
