(a) Average length of the warming period, defined as the time difference (in days) between the average earliest day of year in which lake surface water temperature (LSWT) persistently exceeds 4 °C and the time of maximum temperature, and its relationship with (b) annual mean surface air temperature (SAT) and (c) mean depth. Colours in panel (b) signify latitude. Linear regressions of the statistically significant (p < 0.05) relationships are shown. The map was generated using the MATLAB mapping toolbox43 (URL-https://www.mathworks.com/products/mapping.html).
