THE QUASI-PERIODIC FLUCTUATION OF LARGE-SCALE CIRCULATION AND GRAIN YIELD IN THE LOWER YANGTZE
Using monthly mean sea-level pressure field over the Eastern Hemisphere during 1871-1976,the data of yearly precipitation and of yearly grain yield in the Lower Yangtze are analyzed, and 36-yr. and 2-3-yr. quasi-periodic fluctuations in the circulation pattern-weather-yield system has been found. A fluctuation model is proposed.
