Land cover misclassifications can impact heat and rainfall simulations in East Asia, but the effects are mostly minimal. Using a climate model, researchers found that changes in land cover types can affect heat fluxes in the region, leading to slight temperature increases in the Tibetan Plateau. However, the impact on rainfall is negligible, with most changes likely due to natural variability rather than land cover changes. Overall, uncertainties in land cover reconstructions have little effect on air temperature and rainfall simulations in East Asia, making current land cover maps suitable for regional climate studies in the area.
