Northern East Asian summer monsoon precipitation (NEASMP) and southern East Asian summer monsoon precipitation (SEASMP) appear to be in different correlations with oceanic heat sources in the Pacific and Indian Oceans during pre-monsoon seasons. NEASMP has significant correlations with the tropical oceans, which are positive correlations in the tropical eastern Pacific and Indian Oceans and a negative correlation in the tropical western Pacific (Figure 1). SEASMP has significant correlations with the subtropical oceans, which are a positive correlation in the northwestern Pacific and a negative correlation in the northeastern Pacific (Figure 2). These correlations between EASMPs and oceanic heat sources support the connections between NEASMP and El Ni帽o and between SEASMP and La Ni帽a events, respectively. Predictive models of EASMPs are developed based on the heat sources in the tropical Pacific and Indian Oceans for the NEASMP model and in the subtropical Pacific for the SEASMP model. Predictability for NEASMP is higher than that for SEASMP. This study suggests that the EASM is related to the heat sources not only in the tropical but also subtropical oceans, so the study of dynamical mechanisms between the EASM and surrounding oceans should be interesting.
