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

Table 2

Correlation at 95% significance level between the MO indices and the Mediterranean-averaged variables (𝑃, 𝐸, 𝐸-𝑃, and net heat flux, 𝑄) on annual basis (a) and for winter season (b) at decadal (5-year running means) timescale. (—) indicates that correlation is not significant. The highest correlation for each variable is highlighted in bold.
