“…In September, the streamflow in La Niña month exceeds that in El Niño month and the percentage difference exceeds 63.0 %. Different to the Yangtze River basin, the ENSO influences in the Pearl River are only statistically significant (0.05 level) on autumn and winter streamflow, possibly because of the Pearl River region location in tandem with the strengthening and weakening of sea surface temperature (SST) in the western Pacific (Juneng and Tangang, 2005).…”

Abstract. This paper investigates the single and combined impacts of El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) on precipitation and streamflow in China over the last century. Results indicate that the precipitation and streamflow overall decrease during El Niño/PDO warm phase periods and increase during La Niña/PDO cool phase periods in the majority of China, although there are regional and seasonal differences. Precipitation and streamflow in the Yellow River basin, Yangtze River basin and Pearl River basin are more significantly influenced by El Niño and La Niña events than is precipitation and streamflow in the Songhua River basin, especially in October and November. Moreover, significant influence of ENSO on streamflow in the Yangtze River mainly occurs in summer and autumn while in the Pearl River influence primarily occurs in the winter and spring. The precipitation and streamflow are relatively greater in the warm PDO phase in the Songhua River basin and several parts of the Yellow River basin and relatively less in the Pearl River basin and most parts of Northwest China compared to those in the cool PDO phase, though there is little significance detected by Wilcoxon signed-rank test. When considering the combined influence of ENSO and PDO, the responses of precipitation/streamflow are shown to be opposite in northern China and southern China, with ENSO-related precipitation/streamflow enhanced in northern China and decreased in southern China during the warm PDO phases, and enhanced in southern China and decreased in northern China during the cool PDO phases. It is hoped that this study will be beneficial for understanding the precipitation/streamflow responses to the changing climate and will correspondingly provide valuable reference for water resources prediction and management across China.

“…5) (Juneng and Tangang 2005). In JAS(0), a small reduction of rainfall anomaly in the El Ni no years was observed for all four clusters, which corresponds to a significant negative lag correlation between JAS(0) rainfall and SST (Fig.…”

“…The possible mechanism of such correlation and rainfall reduction was well described by Juneng and Tangang (2005) on the basis of 0.5°× 0.5°rainfall data produced by the Global Historical Climatology Network. They suggested that the strong rainfall-ENSO relationship in the East Malaysia during DJF(0/1) is associated with the anomalous cyclonic/anti-cyclonic circulation that stipulated to be a downstream response to the boomerang-shaped SST anomalies.…”

To determine the spatial and temporal variations in the El Ni no Southern Oscillation (ENSO)-rainfall relationship and seasonal variation in rainfall over northern Borneo, simultaneous and lag correlations between the December February (DJF) average Ni no-3.4 (5°S 5°N, 170° 120°W) sea surface temperature (SST) and rainfall were examined using rainfall data from 18 stations throughout Sarawak during 1963 2003. The lag correlations for June August (JJA) rainfall and SST were significantly negative over southwestern Sarawak (SWS), but the simultaneous correlations for DJF rainfall and SST were significantly negative over northeastern Sarawak (NES). We categorized the 18 stations into four clusters (C1 C4) according to the variation of the seasonal fluctuation in rainfall. C1 and C2 are located in SWS along the convex and concave coastline, respectively, whereas C3 and C4 are located in NES along the convex and straight coastline, respectively. C2 and C4 are also located in the interior in SWS and NES respectively. From the composite of monthly rainfall for all clusters, a decrease in rainfall in JJA was found for all regions in El Ni no years but only for C2, C3 and C4 in DJF during the warm phase of ENSO. The C3 region may be the most vulnerable to El Ni no-induced droughts in Sarawak.

“…Previous studies in Indonesia and Malaysia, have established a significant relationship between rainfall variability and ENSO events (Aldrian & Susanto 2003;Chang et al 2004;Gomyo & Koichiro 2009;Tangang & Juneng 2004). To be more specific, positive correlation has been observed between SE Asia rainfall anomalies (SEAR) and ENSO evolution, where precipitation patterns are found to be highly affected by the irregular ENSO-related sea surface temperature (SST) anomalies (Juneng & Tangang 2005). The same climatic signals were captured further by Cobb et al (2007) with lighter isotope of δ 18 O (1 to 2 ‰) from cave dripwater sample in Gunung Mulu, Sarawak during the weak La Niña in 2005/2006.…”
