Time series of volume-averaged mesoscale (a)\(\:{APE}^{0}\), (b)\(\:{KE}^{0}\:\)and submesoscale (c) \(\:{APE}^{1}\), (d)\(\:{\:KE}^{1}\:\)(right label, in \(\:{m}^{2}/{s}^{3}\)) and their budgets (left label, in \(\:{m}^{2}/{s}^{2}\)) within the upper 200 m over the MESM region from November 30, 2016 to February 20, 2017. The four typical moments shown in Figs. 4, 5, 6, 7, 8 and 9 are marked by vertical dotted lines in each panel. Note only part of energy budget terms are illustrated in submesoscale panels (c) and (d), and the red axis marks on the left are for energy budget terms while the black axis marks on the right are for energy (black lines), and the slope of an energy line represents its time tendency.
