(a) Correlation coefficients between tendency and the contribution of horizontal advection (including SH and LH; −(/r∂φ + ()/(C_pd)· ∂q/r∂φ − (/∂r + ()/(C_pd)·∂q/∂r); black), the contribution of vertical advection (including SH and LH; −/∂z − ()/(C_pd)·∂q/∂z; green), LH from the local variation of q (−()/(C_pd)·∂q/∂t; purple), and the residual term (red), calculated using the 200 sets of data of the four cycles. Areas outside the gray mask indicate statistical significance at the 99% confidence level. (b) Variation of the averaged tendency with height.
