The divergence between statistical optimality and climatological interpretability. The need to resolve physically distinct precipitation regimes that remain aggregated at lower K values. The challenge of capturing physically meaningful hydroclimatological structures linked to global atmospheric dynamics.

Further research is needed to explore the physical mechanisms underlying seasonal precipitation changes in Central Asia. Studies should examine the impacts of external forcings on precipitation in other regions. Research should focus on developing more accurate and reliable models for predicting future precipitation changes.
