METHOD OF ACTIVE INFLUENCE ONTO HAIL PROCESSES Russian patent published in 2008 - IPC G01W1/00 

FIELD: agriculture.

SUBSTANCE: method can be successfully used for protection of crops against hail beating. Hail processes are separated to objects of influences of 1^st, 2^nd, 3^rd and 4^th categories and active layer of cloud medium is selected due to radiolocation probing of hail cloud in it. Active layer of cloud medium is restricted from the bottom by level of crystallization temperature of reagent at -6°C and it is restricted by isocontours of values of radiolocation reflectivity at sides within 0-35 dBZ achieved due to cyclical measurement of radar signals on base of discrete spatial points. Value of height of disposition of maximal radio-location reflectivity H_zm is introduced additionally into 2^nd category, which height is determined from data of radar station and continuous sawing of crystallizing reagent twice for any new observation for objects from 2^nd category, three times for objects from 3^rd category and four times for objects fro, 4^th category. Crystallizing agent is introduced once more onto same area, moreover for objects from 3^rd and 4^th categories, pre-cloud atmosphere is preliminary sowed from side of invasion of objects mentioned before, the pre-cloud area is disposed among those objects and radiuses of action of rocket assemblies at protected territory.

EFFECT: improved efficiency of influence onto hail processes.
