METHOD OF ACTIVE IMPACTS ON CITY PROCESSES

摘要

FIELD: agriculture. ^ SUBSTANCE: method can be successfully used for protection of crops against hail beating. Hail processes are separated to objects of influences of 1st, 2nd, 3rd and 4th 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 Hzm is introduced additionally into 2nd category, which height is determined from data of radar station and continuous sawing of crystallizing reagent twice for any new observation for objects from 2nd category, three times for objects from 3rd category and four times for objects fro, 4th category. Crystallizing agent is introduced once more onto same area, moreover for objects from 3rd and 4th 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. ^ 6 dwg
