The Mediterranean Oscillation Teleconnection Index: Station-Based versus Principal Component Paradigms

Table 3

Mediterranean averaged anomalies in the 1958–2008 period during the positive (higher quartile) and negative (lower quartile) phases of the selected MO_PC index. Units are mm/year for 𝑃, 𝐸, and 𝐸-𝑃 and W m⁻² for 𝑄. Anomalies of opposite sign across the basin are shown separately by a /. The fraction of points where the anomaly is significantly different from zero is shown in brackets.
