Precipitation enhancement methods are analyzed for comparison and combinations: acoustic treatment in clouds, heat up flow, powder introduction. Artificial air up flows are considered with account of initial overheating 30 - 70 C and heat flow power 2 - 200 MW in area up to 120 m2 on the ground. Proposed and reviewed analytical models describe the dynamics of air jets with introduced powder, in particular black powder for its sun heating to get additional jet altitude. Resulting mass or number concentrations of powder can be calculated inside whole jet volume using presented analytical equations. As a good heater, an acoustic siren resonator bell enables its double use and double its benefits. One of the main advantages of acoustic treatment in natural clouds method is negligible small sound losses at applied low frequency f = 40 - 300 Hz. The experiments are presented for optimized acoustic sirens using Bessel form resonator, which was successfully applied to get effective frequency selection. Proposed algorithms describe and optimize acoustical power with low frequency in real clouds for sure collision of droplet inside spectrum to precipitation enhancement.
