Abstract: This paper presents the identification, monitoring and Instantaneous analysis of thunderstorms over Ho Chi Minh City area using TITAN software.  The Tstorms2Symprod algorithm in TITAN is used to determine the thunderstorm cells and movement of the thunderstorm cells in the next hour, through the real-time reflectivity, based on smoothing of the TREC vectors. Integral along time using Lagrange diagrams. These integral diagrams within 60 minutes create 10 products every 6 minutes. The results of this software is validated with observation data at the station, the Cmax product (radar maximum reflectivity) and the Himawari 8 satellite image. The results show that the TITAN model can capture the location, direction and velocity, and the scale of the thunderstorm cells. This is important for very short-range precipitation forecast for Ho Chi Minh City.
