From: Limited global intensification of weak tropical cyclones over the past 30 years
Global distributions of a weak TC occurrences and b drifter observations that located within the vicinity of these weak TCs, both on 2° × 2° (latitude × longitude) grids for the period 1993–2022. The total number of weak TCs recorded was 45,299, and 5538 (12.23% of the total) were observed between 10°S and 10°N (indicated by the regions between red lines). The total number of drifter records was 128,960, with 13,373 (10.37% of the total) under weak TCs.
