  1. For each monthly climate variable and station (Minusinsk—MIN, Cheryomushki—CHER), the first two columns show mean ± standard deviation of the difference d between station and regional (REG; see text) values over sub-periods before and after launching of the turbines in the respective dams; the third column (Δ) indicates the change in that difference from the earlier to later sub-period, significant (p < 0.05) changes are written in bold.
