Fig. 3: TCF origin analysis applied to the five coastal regions.
From: Anthropogenic forcing changes coastal tropical cyclone frequency
a–d The US Atlantic coast under the anthropogenic aerosol effect. a Local TCF trend change under the aerosol effect as shown in Fig. 2. b–d The contribution of each grid to the total TCF change (\(\varDelta {df}\)) in the magenta box due to genesis change (\(\varDelta d{g}_{B,{A}_{o}}\)), TC track change (\(\varDelta d{t}_{B,{A}_{o}}\)), and nonlinear combination of genesis and track changes (\(\varDelta d{n}_{B,{A}_{o}}\)). e–h As in (a–d), but for the Hawaii region under the anthropogenic GHG effect. (i–l) As in (a–d), but for the South China Sea under the anthropogenic GHG effect. m–p As in (a–d), but for the Japan-Korea region under the anthropogenic aerosol and GHG effects. q–t As in (a–d), but for the Madagascar region under the anthropogenic aerosol effect. The magenta boxes show the same regions as in Fig. 1a. The green boxes highlight the key regions with the genesis and track contributions.
