Two charts show the way that ENSO is asymmetrical. On the left, a chart labeled “Diurnal variation” shows how sea surface temperature is higher during the day than at night. On the right, a chart labeled “ENSO asymmetry” shows two lines, with time on the x axis and temperature on the y axis. Both lines peak in the middle, but the red line labeled “El Niño” has a higher peak than the blue line labeled “La Niña.”
