Abstract

In this paper, based on the synoptic charts, JRA55 re-analysis maps and high-resolution simulation (3km) by WRF model with FNL data driven to investigate the causes of heavy rainfall from 24 to 26 October 2016 in the Southern region. The results show that the equatorial low trough which located above the Ca Mau peninsula interacted to a tropical cyclone in the Bay of Bengal area that induced this heavy rainfall event . In the early time, the TC locate close Southern region that indicated the northwest wind direction. And when TC moved away, the dominant wind direction is eastward. This interaction created the turbulence in the atmospheric circulation and moisture from offshore transported into the Southern region that causing heavy rainfall for Ho Chi Minh city from 24 to 26 October 2016.
