冬半年磁扰与磁静后我国温度的变化

THE TEMPERATURE VARIATION AFTER THE MAGNETIC DISTURBED AND QUIET DAYS DURING SOME WINTER-HALF YEARS IN CHINA

  • 摘要: 本文应用1956-1959和1953-1955两个时期内冬半年各月逐日国际磁情Ci指数,按照一定标准挑出磁扰和磁静两类关键日期,然后用重迭时序法分析我国若干气象台站在两类关键日期前后的温度变化。结果得到在磁扰和磁静后十天内我国温度演变的具体过程,可以在我国冬半年中期温度预报中参考。

     

    Abstract: In this paper the daily magnetic Ci-indices during the winter-half years of the period of 1956-1959 and 1953-1955 are used to ascertain the magnetic disturbed and the magnetic quiet days.The total number of each kind of the key-days at different periods is around 30.Hence in any month the number of key-days is always less than three.The method of superposed epoch is used to analyze the temperature variations after those key-days at 28 stations in 6ina.The results thus obtained are shown by statistical methods to be useful in the medium-range temperature forecasting in China during the winter-half year.
