Impact of Preceding El Niño and the Indian Ocean Dipole on the Southern China Precipitation in Early Summer

Table 2

Designs of the numerical experiment.

Experiment names	Application	Forcing of SST	Duration of the integration
CTL	Getting the model climate	The climatological SST varying seasonally within the CAM3.0	Integration for 20 years from 1 September
SEXP1	Getting the single influence of PE and PI	SEXP1-PE: P-SSTA imposed over TP	Ten different integration durations
		SEXP1-PI: P-SSTA imposed over TIO
SEXP2	Diagnosing the stability and sensitivity of the model	SEXP2-PE: various intensity P-SSTA* imposed over TP	Integrated from September to next June
		SEXP2-PI: various intensity P-SSTA* imposed over TIO
SEXP3	Getting the combined influence of PEI	SEXP3-PEI: P-SSTA imposed over TP and TIO	Integrated from September to next June

∗Based on P-SSTA, the imposed SSTAs were modified by adding/subtracting 0.5°C at all grid points over TP or modified by adding/subtracting 0.3°C at all grid points over TIO.
