Abstract :

The present study investigates the relation of temperature, rainfall and pressure anomaly of Cox’s Bazar situated at the southeastern Bangladesh with ENSO parameters and pressure anomalies at Tahiti, Darwin, Darwin minusTahiti and Darwin minus Cox’s Bazar. The strudy shows that the temperature and rainfall do not exhibit much of systematic relation with SOI. Both temperature and rainfall exhibit weak correlation with SST anomalies of Nino4 region. The correlations of the pressure anomaly of Darwin minus Tahiti and Darwin minus Cox’s Bazar are 0.47 with 5 and 11 months moving average data. Tahiti and Darwin pressure anomalies are strongly correlated with Cox’s Bazar. The pressure anomaly at Darwin fluctuates in opposite phase with Tahiti and Cox’s Bazar. These relations may be used for developing long term prediction model of south-east monsoon of Bangladesh coastal zone.
