Yi. Stozhkov et al., RAINFALLS DURING GREAT FORBUSH DECREASES, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 18(3), 1995, pp. 335-341
The changes of rainfall values during great Forbush decreases recorded
by the low-latitudinal neutron monitor of Huancayo (47 events from 19
56 through 1992) were examined. The data on precipitations were taken
from the State of Sao Paulo and from the Amazonian region, Brazil. As
a rule, the data from more than 50 meteorological stations were used f
or each events. The main result is the following: during strong decrea
ses of cosmic-ray flux in the atmosphere (great Forbush decreases) the
precipitation value is decreased. The effect of rainfall changes is s
een more distinctly if wet seasons are considered.
