Short-term forecasts from global and regional models show Chengdu's August 24 maximum temperature likely centering on 34–36 °C, with trader probabilities tightly clustered because ensemble spreads remain wide. Key differentiating factors include the strength and position of the western Pacific subtropical high, which modulates subsidence and solar heating over the Sichuan basin, alongside local effects such as urban heat retention and reduced evaporative cooling after recent rainfall. Model disagreement on low-level wind patterns and afternoon cloud cover creates the observed 22.5 %–13.5 % spread across the 34 °C, 35 °C, and 36 °C outcomes. New runs from agencies including the China Meteorological Administration and ECMWF expected within the next 24–48 hours will narrow uncertainty ahead of the 24-hour verification window.
