According to the relationship analysis between tropical cyclones landing in China and El Nino years and La Nina years, some results are obtained as follows: (1) There are less frequen.
On the basis of climate data of 10 cities in recent 46 years, the relation between climate change in Shaanxi province with E1 Nino and La Nina is studied.
Based on temperature and salinity data from 17 cruises along the 165°E section during 1984-1988 which were attained by the Sinuo-US cooperative air-sea interaction study and ORSTOM center in Noumea, the anomalous variations of temperature and salinity structures in the upper layer of the ocean in the periods of 1986-1987 E1 Nino and 1984-1985, 1988-1989 La Nina events were analyzed.
Bas ed on the observational records covering the period from 1951 to present, the ch aracteristics of precipitation changing over North China and its possible connec tion to El Nio were studied using tendency analysis, correlation analysis and wavelet analysis.
厄尔尼诺对华北降水的变化有重要影响,发生厄尔尼诺时,华北春季降水偏多,夏季和秋季降水显著偏少。
2.
The possible influences of El Nio events on precipitation of Henan are discussed by comparing the period variation of SST cold or warm structures with dry or wet changes of Henan precipitation.
