ABSTRACT
The Central Pacific Ocean (CPO) is an important area for the manifestation of El Ni?o/La Ni?a. In this paper, heat budget parameters over the CPO region (5°N-5°S; 120°W-170°W), and their relation with Sea Surface Temperature (SST) are examined with the National Centre for Environmental Prediction (NCEP) reanalysis data for the period 1979 to 2013. The heat budget parameters over CPO reveal that the seasonal change of NHF is observed with a minimum peak in March and maximum peak in December; the heat loss at the sea surface in winter is less than in summer. The variations in heat budget parameters are following El Ni?o and La Ni?a phenomena. The results reveal that the seasonal variation of net radiation and heat budget parameters are indicating decrease trend, whereas net heat flux shows an increasing trend. Sea Surface Temperature is having a positive correlation with net heat flux (0.43) and a negative correlation with net radiation (-0.61) and heat budget (-0.67). In the ENSO years, net radiation and heat budget are significant inverse relation with SST, whereas the net heat flux depicts is a positive correlation.
