Fig. 8 Temporal variability in annual temperature (°C) over LH, GH and KH as depicted by
ERA-I (a–c) and CRU-TS (d-f). (a) and (d) depict long term (1985–2015) trends in annual temperature by ERA-I and CRU-TS respectively, (b) and (e) depict short term (1985–2000) trends in
annual temperature by ERA-I and CRU-TS respectively, (c) and (f) depict short term (2001–2015)
trends in annual temperature by ERA-I and CRU-TS respectively. Here solid circles (●) depict
statistical significance at α = 0.05
