Some Relationships between the El Nino and the Summer Chilling Damage in Northeast of China in Association with the Planetary Motion
The relationship between the planetary motion and El Nino was used to classify El Nino. It was found that some types of El Nino could cause the summer chilling damage (SCD) in northeast of China,but other types could not. Statistically,SCD happens easily in the next years when one of the three planetary (Mars,Jupiter,Saturn) was opposite to sun at the extreme negative value of helocentric celestial latitude,or in the years when Jupiter was opposite to sun at the extreme positive value of helocentric celestial latitude. A series of SCD can happen when Saturn moves ranging from 19 to 121 degress of celestial longtitude. The time that SCD will happen in future can be predicted.
