Contours of S2 (first column), N2 (second column) and S2/N2 (third column) for ISW #4 (first row), ISW #7 (second row), ISW #8 (third row) and ISW #11 (forth row). The black contour lines are the isotherms from 12 to 29 °C with an interval of 0.5 °C. The magenta contour line is the 18 °C isotherm. The yellow and cyan curves are the contours of Ri = 0.25 and Ri = 0.1, respectively. The time axis is relative to the arrival time of the ISWs (see “Methods” for details).
