Erratum: wet bias of summer precipitation in the northwestern Tibetan Plateau in ERA5 is linked to overestimated lower-level southerly wind over the Plateau

Abstract

We sincerely apologize for a technical error revealed in this article, published in 2023: the spectral nudging process at the upper levels was not functioning as intended. Consequently, the final results presented in the original work are based on WRF downscaling without active spectral nudging. To assess the potential impact of this error on the study’s main conclusion, we conducted two additional experiments using the same WRF version 3.7.1. Results show that the technical error does not alter the main conclusion of the study: the ERA5 overestimation of summer precipitation over the northwestern Tibetan Plateau is associated with an overestimated lower-level southerly wind.
