Overview

Comparative analysis evaluated model performance in various regions, highlighting verification skill scores and implications for numerical weather prediction.

Key Points

  • The GDAS model exhibits lower errors in correlation scores compared to NCUM during the 2024 summer monsoon.
  • Daily, weekly, and monthly verification skill scores were calculated against radiosonde observations for both models.
  • Significant regional variations in performance were noted, with greater errors in geopotential height and temperature in the South Pole and Tropics.
  • These findings support improvements in numerical weather prediction systems at operational centers globally.
