Overview

This analysis evaluates urbanization's impact on climate using RegCM5 in Hanoi and Ho Chi Minh City, showing enhanced results with updated data.

Key Points

  • The 2 km RegCM5 simulations outperform coarser resolutions, particularly benefiting urban climate modeling.
  • Incorporating updated urban data enhances the model's accuracy in capturing urbanization effects during late afternoon to midnight.
  • The urban heat island effect is more pronounced in Hanoi compared to Ho Chi Minh City, especially during higher background temperatures.
  • The study underscores the advantages of convection-permitting simulations over traditional coarse-resolution models.
