Fundamental 
 

  Previous studies suggest that it is reasonable to expect a direct relationship between sea surface temperature and deep convection cloud(SST-DCC), however, the relationship between the local SST and DCC over warm ocean SST> 27°C) is rather complex because of the influence of large-scale atmospheric dynamics that govern atmospheric convergence in the lower and middle troposphere and divergence aloft [Graham and Barnett, 1987; Waliser and Graham, 1993; Zhang, 1993; Meenu et al., 2012].

 

  Waliser et al. (1993) found that the characteristic of the relationship between SST and DCC is such that at temperature between 27 and 29°C, convection increases with increasing SST, but above 29°C(i.e. in the western tropical Pacific during boreal summer), the intensity of convection observed tends to decrease with increasing SST.

 

  That is, The SST-DCC correlation is highly positive in the central-to-eastern tropical Pacific, the core region of interannual variability associated with El Nino-Southern Oscillation (ENSO), On the other hand, the overall summer SST-DCC relationship has a negative correlation in the western tropical Pacific, this relationship experiences a significant interannual variation [R Wu and Kirtman, 2005; B Wu et al., 2009; Kumar et al., 2013].
