AN INVESTIGATION OF FORECASTING THE CROP YIELD WITH SEA SURFACE TEMPERATURE DATA

In this paper, the relationship between the crop yield in three different regions, the northern part of China, the northeast China and Heilongjiang Province, and the monthly mean sea surface temperature (SST) in the northwest Pacific Ocean is analysed preliminarily; the time and space distribution of the sea areas with high value correlation coefficients (HVCC) between the meteorological crop yield (MY) and the monthly mean SST is given; and crop yields in these regions are simulated by the monthly mean SST. Results obtained show that the stabler relationship between the crop yield in some large regions and the monthly mean SST is presented, so that we can forecast the crop yield in these regions using the monthly mean SST of the sea areas with HVCC.
