英文摘要	In this study, we examine the different seasonal precipitation anomaly patterns in Central Asia associated with the cold-tongue (CT) El Nino and warm-pool (WP) El Nino from the El Nino developing autumn to the decaying spring based on the Global Precipitation Climatology Centre (GPCC) full data reanalysis version 2018 (GPCC V2018) data set. Overall, El Nino are associated with more precipitations over Central Asia, but significant discrepancies can be found in the precipitation anomaly spatial patterns associated with the two types of El Nino from the El Nino developing autumn to the decaying spring. The precipitation associated with CT El Nino is mostly concentrated in the plains and hilly areas of Central Asia and is more dispersed in space. Whereas the precipitation associated with WP El Nino is mostly concentrated along Pamirs and Tian Shan Mountains with consistency throughout the autumn before El Nino peaks to the spring when El Nino decays. Also, the strength of the positive precipitation anomaly associated with WP El Nino is significantly stronger than that of CT El Nino. The analysis of anomalous atmospheric circulation caused by two types of El Nino shows that the interconfiguration of anomalous high pressure in the south side of Central Asia at low and middle latitudes and anomalous low pressure and anomalous high pressure in the high latitudes of Eurasia affects the southwest water vapor flux and north side water vapor flux in Central Asia, thus causing different effects of different types of El Nino on precipitation in Central Asia at different stages. The spatial consistency of the WP El Nino effect on precipitation in Central Asia over three seasons may be related to the upward branch of the anomalous Walker circulation over the Indian Ocean induced by it.
