Details on data sets are given in Appendices S1 and S2.

Tmax – average maximum temperature; Rain – rainfall sum; Pres – average barometric pressure; Wind – average wind speed; AirHum – average air humidity.

‘+’ significant positive effect; ‘−’ significant negative effect; ‘NS’ not significant at α = 0·05; ‘n.a.’ data not available.
