Fig. 2: Responses of subsurface ocean to pre-genesis tropical cyclones (TCs).
From: Crucial role of subsurface ocean variability in tropical cyclone genesis
a Changes in depth of the 26 °C isotherm (D26) due to pre-genesis TCs. b Histogram of D26 changes. The dotted lines represent the 10th and 90th percentiles, respectively. c, Same as a but for the ratios of D26 change to the standard deviation of D26. d Same as b but for the ratios in c. The dotted lines represent ratios of −0.5 and 0.5, respectively. The D26 changes are obtained from the daily GLORYS12v1 product. The standard deviation of D26 is obtained by deriving it from the monthly GLORYS12v1 product and applying a 1-year high-pass filter to remove interannual and decadal variabilities. For each grid, the standard deviation is calculated using the monthly D26 data from 1993 to 2022.
