Coupled influence of Western Pacific moisture anomalies and mid-tropospheric humidity on October precipitation in Yunnan Province Southwest China

Key Points

• October precipitation in Yunnan Province is significantly influenced by Western Pacific moisture anomalies, contributing to local climate variability.
• This study demonstrates a connection between mid-tropospheric humidity levels and changes in precipitation patterns in the region.
• Observational analysis across climate records highlights the coupling of moisture anomalies and humidity as critical factors for understanding regional rainfall.
• Findings indicate that understanding moisture dynamics can help improve predictions of precipitation in Yunnan Province and similar climate regions.
