The characteristics of the ongoing season in Southwest China were excessive precipitation (17 percent above the twelve-year average),lower temperature (0.3°C below the average) and normal PAR accumulation. Allthese features led to an increase in biomass by 5 percent. In October, the dry weather inhibited the growth of the crops in southwest China. In early November, southeast Sichuan, southwest Chongqing, and northwestern parts of Guizhou all experienced excessive rainfall along with limited sunshine (lesst han 40 hours of bright sunshine per month) which reduced crop photosynthesis.Furthermore, lower temperature in December limited the growth of crops. In January, favorable temperature and adequate light boosted the growth of crops.The cluster and profiles of NDVI show that crop condition in the east of Sichuan province was better than in the other areas. The maximum VCI in mostregions of Southwest China was above 0.8 which indicates a positive outcome ofthe season is not unlikely.
