Spatiotemporal Changes of Rainfall Erosivity in Loess Plateau, China

Table 2

Correlation coefficient between the rainfall parameters and geographical attributes (𝑛=42).

Rainfall parameters	Longitude	Latitude	Altitude
𝑃𝑦	0.35 (0.02)	−0.68 (<0.001)	−0.07 (ns)
MFI	0.56 (<0.001)	−0.45 (0.002)	−0.20 (ns)
PCI	0.14 (ns)	0.89 (<0.001)	−0.21 (ns)

The exponent between parentheses is the 𝑃 value; 𝑃_𝑦 is annual rainfall (mm); MFI is modified Fournier index; PCI is precipitation concentration index.
