Graphical Abstract Published


Plain Language Summary: A convective rainband developed along a non-classic front (outer front), which formed to the north of a warm front, associated with an extratropical cyclone. The rainband produced record-breaking heavy rainfall to Miyake Island, Japan, on 8 January 2017. This study examined roles of surface latent and sensible heat fluxes from the Kuroshio Current in the intensification of the rainband using cloud-resolving numerical experiments. Results derived from the numerical experiments indicated that the heat fluxes, especially the latent heat fluxes, enhanced the rainband by increasing the moisture content and convective instability.
