cloud modification
1.It is considered that:(1) The structure of the return current process precipition, NE cold flow at low level and SW warm and wet flow above, form the warm front precipitation cloud system in favour of the weather modification cloud seeding;
2.he idea and procedure for developing high efficient AgI pyrotechnics used in weather modification are given in this paper. Two formulations (BR-88-5 and BR-91-Y) of pyrotechnic with high nucleating effectiveness have been obtained after a number of screen tests carried out in 2m3 cloud chamber.
