The role of orographic effects on heavy rainfall event over central Vietnam in October 2021

The paper "The role of orographic effects on heavy rainfall event over central Vietnam in October 2021" use observation data and high-resolution (3 km) simulations from the WRF model, driven by FNL data, to investigate the causes of heavy rain over Central Vietnam from 22nd to 29th October 2021. Our findings confirm the significant role of topography in causing heavy rain. In terms of the atmosphere’s vertical structure, the surface’s northeast wind, almost perpendicular to the Central region’s topography, combined with the east wind and trade winds above, caused strong convection.
