Fig 4. Climate diagrams during the 65-year period analyzed (1956-2021) of five meteorological stations, representing the latitudinal and longitudinal geographical gradient of the area where the geographical spread of the disease has been recently described.

Each plot indicates: (a) the station; (b) the period of years represented by the data; (c) the geographical coordinates in decimal degrees; (d) altitude in meters; (e) the mean yearly temperature; (f) the mean yearly precipitation; (g) the mean maximum temperature during the warmest month; (h) the mean minimum temperature during the coldest month; (i) the mean monthly temperature curve; (j) the mean maximum monthly temperature curve; (k) the potential evapotranspiration as proposed by Hargreaves and Samani (1985) [52]; (l) the mean monthly precipitation curve; (m) the wet and (n) dry seasons; (o) the months when the mean monthly potential evapotranspiration exceeds 100 mm; (p) the months with a mean minimum temperature under 0 °C; (q) the mean duration of the period without freezing and (r) the 10 °C temperature threshold below which fascioliasis transmission due to F. hepatica is unlikely. Months labels in the X-axis are presented as July (J), August (A), September (S), October (O), November (N), December (D), January (J), February (F), March (M), April (A), May (M) and June (J).
