Evaluating Changes in the Moisture Sources for Tropical Cyclones Precipitation in the North Atlantic That Underwent Extratropical Transition

Abstract: In this study, we investigated the changes in the origin of moisture for the precipitation associated with tropical cyclones (TCs) after extratropical transition (ET) over the North Atlantic Ocean basin from 1980 to 2018. We analyzed the 24 hr before and after the occurrence of ET events. By applying a TC‐centric methodology we found that the moisture uptake (MU) occurred predominantly in the south and southwest sectors within ∼2,000 km of TC center before ET and from the southwest and west sectors after ET.

“…Also, in WRF‐based simulation studies, it is necessary to account for the internal model variability due to perturbations in the initial conditions of the WRF model (Ancell et al ., 2018; Bassett et al ., 2020). Previous studies have also used the Lagrangian approach for identifying the moisture source for cyclones over different oceans, including the North Indian Ocean (Coll‐Hidalgo et al ., 2022a; Coll‐Hidalgo et al ., 2022b; Liu et al ., 2022; Pérez‐Alarcón et al ., 2022a; Pérez‐Alarcón et al ., 2022b; Pérez‐Alarcón et al ., 2022c; Pérez‐Alarcón et al ., 2023). However, the study over the North Indian Ocean (Pérez‐Alarcón et al ., 2022b) was based on ERA‐Interim data, which has a coarse resolution of 1° resolution.…”
