CHARACTERIZING EFFECTS OF DIFFERENT ENSO PHASES ON SEA SURFACE TEMPERATURE IN THE VIET NAM EAST SEA

Tóm tắt

The effect of different ENSO phases on Sea Surface Temperature (SST) has been an intensive effort to find the link between this basin-scale climate pattern and one of the most critical marine parameters. This issue, however, has not been well-studied in the Viet Nam East Sea (VES). This study examined the effect of different ENSO phases on SST in the VES by applying a series of statistical techniques on both satellite data and observed data from coastal stations. We find a significant correlation between ENSO and satellite-based SST data in the winter season (r = 0.56). We recognize a stronger relationship of ENSO-SST in the southern stations (with r varies from 0.47 - 0.83). We then compared the impact of different ENSO phases for the period of 1990 - 2019. Our results reveal that the extreme El Nino event 1997/98 had impacted SST strongly than any other event. In addition, we find that the response of SST to ENSO phases does not depend on intensity. The outcomes of this work may significantly contribute to the understanding of the effects of ENSO on marine parameters in the VES.
