RESEARCH ON DROUGHT / FLOOD INFLUENCE FACTORS IN CHINA

  • Publish Date: 1993-03-20
  • In the fifth paper listed in the references, East China was divided into eight drought/ flood regions. But we, taking earth rotation velocity, sunspots, southern oscillation, etc. as the influence factors, through step-wise regression analysis and typical analysis, discussed drought/ flood influence factors of the eight regions. On the basis of them, applying spectrum analysis, we calculated the cycles of every influence factor variation and cycles of drought/ flood variations of every region as well as cycles of vibration between them. The results indicate that the drought/ flood influence factors of East China are southern oscillation, earth rotation velocity, etc. Specially, the influence of EL-Nino is more evident to drought/ flood in most regions than that of others. Generally, there are good correlations between the year of EL-Nino and the year of drought/ flood in most regions. The ways of these factors influencing drought/ flood are shown in lag correlation, by 2-5-year high-frequency vibration cycle.

RESEARCH ON DROUGHT / FLOOD INFLUENCE FACTORS IN CHINA

Abstract: In the fifth paper listed in the references, East China was divided into eight drought/ flood regions. But we, taking earth rotation velocity, sunspots, southern oscillation, etc. as the influence factors, through step-wise regression analysis and typical analysis, discussed drought/ flood influence factors of the eight regions. On the basis of them, applying spectrum analysis, we calculated the cycles of every influence factor variation and cycles of drought/ flood variations of every region as well as cycles of vibration between them. The results indicate that the drought/ flood influence factors of East China are southern oscillation, earth rotation velocity, etc. Specially, the influence of EL-Nino is more evident to drought/ flood in most regions than that of others. Generally, there are good correlations between the year of EL-Nino and the year of drought/ flood in most regions. The ways of these factors influencing drought/ flood are shown in lag correlation, by 2-5-year high-frequency vibration cycle.
