ENSO Related Rainfall Variability over Thailand
The relationship between ENSO, seasonal rainfall in South Africa
El Niño-Southern Oscillation (ENSO) has important roles to play in relation to Southeast Asian rainfall anomalies. This study analyzes the variability of local seasonal rainfall over Thailand. The empirical orthogonal function (EOF) was employed. The rainfall data used APHRODITE’s data and the data from Thai meteorological department 26 station. The next part, the relationship between ENSO using the sea surface temperature (SST) the Niño3, Niño3.4 index with principal component time series (PC’s) of the most dominant mode each season. The Pearson’s correlation was employed. The result show the Niño3.4 SST index is mostly correlation to the MAM season of rainfall over Thailand. The correlation is negative, because a high SST anomaly gives a low rainfall anomaly, and a low SST anomaly gives a high rainfall anomaly.
