Fig. 2: Modelled lake surface water temperature dynamics.
From: Global lake thermal regions shift under climate change

a Mean lake surface water temperature. b Seasonal range in lake surface water temperature. c Map of the nine lake thermal regions. Locations represent 2° grids where lakes exist based on the HydroLAKES database (see methods); grey areas are where lakes are absent in the database. Lake surface temperatures and the thermal regions were calculated by the lake model driven by ERA-Interim data from 1996 to 2011.
