Multiple climate modeling studies demonstrate that future climate change scenarios significantly alter atmospheric circulation patterns and weather regimes, which in turn affect regional weather predictability and extremes.
The claim states that synoptic weather predictability and atmospheric circulation patterns change under various climate change scenarios. Papers [0], [6], and [11] explicitly analyze future climate scenarios (using CMIP5/CMIP6 under various SSP pathways) and show that circulation patterns, frequencies, and persistence regimes undergo statistically significant changes due to global warming. Thus, the evidence strongly supports the claim.
