In other words, the increased solar wind at sunspot
maximum keeps cosmic radiation out of the solar
system and away from the earth. During the years of
sunspot minimum, cosmic radiation is strong enough to
penetrate the solar aura and reach the earth's
atmosphere.


Thunderstorms and the Moon: It has been shown that
the maximum in thunderstorms coincides with maximum
geomagnetic activity. In addition, it has been shown that
thunderstorm activity is modulated by lunar position.
The greatest numbers of thunderstorms occur after
either a New or a Full Moon. Thunderstorm frequency
reaches a maximum two days after a Full Moon and
remains high for most of the third quarter.


The Moon and Geomagnetic Activity


The Kp-geomagnetic index varies with the lunar phases.
