Observational analysis demonstrates no significant short-term changes in storm patterns or local weather following mega-dam construction, suggesting minimal immediate impact on regional climate.
The Three Gorges Project (TGP) – which involved the construction of a large dam between the cities of Chongqing and Yichang – resulted in major changes to the landscape of the surrounding region, creating wide areas of open water on its completion in 2003. This article investigates the immediate effects of the TGP on storm event patterns and local weather in an area adjacent to the Three Gorges Reservoir using daily weather variable data from the period 2001–2015. Storm event patterns were derived from daily rainfall data and statistically tested to see whether significant changes in the patterns could be detected. The results show that the TGP did not significantly influence patterns of storm events or local weather over the short term.
