N2 - The decay of tropical cyclone Cempaka into a tropical depression was followed by the emergence of a new tropical low in the southwest of Bengkulu. This tropical low status was upgraded on 29th November 2017 at 19.00 LT into tropical cyclone Dahlia. In this study, an analysis of several weather parameters was carried out during the occurrence of tropical cyclone Dahlia, including wind conditions, divergence, sea surface temperature, geopotential height, air temperature, as well as the movement of water vapor transport on 30th November–1st December 2017. The influence caused by the presence of tropical cyclone Dahlia on atmospheric conditions is described in this study. This research utilizes ERA-Interim reanalysis data from the European Center for Medium-Range Weather Forecast (ECMWF). The method used is the descriptive method. The results showed that the sea surface temperature in the study area supports the formation of a tropical cyclone. The significant water vapor transport causes high water vapor intensity and low geopotential height during the research period. The cyclonic pattern is visible in the streamline, and the divergence conditions during the research period are generally negative in the lower tropospheric layers and positive in the upper tropospheric layers. The presence of MJO, Equatorial Rossby Waves, and Kelvin Waves in the same location and time supported the formation of TC Dahlia.
