Agitated Sunspot Cause Trouble If the lights in your
house keep flickering, blame frequent sunspots. A sunspot is
actually charged particles flying at the speed of 3 million kilometers an hour
out of the surface of the sun to form sun storms. (1)
The earth, which is directly energized by the sun, is
influenced by sun storms in a number of ways. (2)
Wireless short-wave communication, which depends on the wave’s
reflection against this layer of atmosphere, is likely to be jammed. It is said
that mobile phone communication may be affected too.
(3) According to a research conducted by the Russian scientists
from 1957 to 1960, the frequency of earthquakes can be linked to the movement of
the sunspots. Though little research has been carried out about
how exactly the sunspot will negatively harm the health of the people, a paper
published by a North Korea observatory says that sun storms may cause an
increase in the incidence of heart disease and skin disease. (4)
. Besides, the nervous system is also affected, and
traffic accidents are more frequent when sunspots are active. It
is hard to say when the sunspots are most violent during their active year, but
generally one active period is believed to last possibly eight days. Not long
ago there were two violent sun storms breaking out, which seriously affected
mobile phone communication, etc. in many parts of the world. (5)
. A. Ionosphere is high above the earth.
B. One is that the magnetic filed of the earth is much disturbed because
of the sun’s interference in the ionosphere which is 80 to 500 kilometers above
the earth. C. Scientists also say that the active movement of
the charged sun storm also has effects on earthquakes. D. Every
11 years, the sun, as its energy accumulate inside up to a certain point, will
send out streams of charged particles, which affect the earth in different
ways. E. But the communication situation in each case returned
to normal in about 24 hours. F. So, scientists warn that people
going outdoors should be careful to protect their exposed skin and eyes with
clothes, umbrellas and sunglasses from the strong sunlight rich in ultraviolet
rays.
