TITLE Climate Classification Analysis for Chinese Provinces Using Machine Learning Models
ABSTRACT This study develops a sophisticated machine learning pipeline to classify climate characteristics across 34 Chinese provinces, leveraging the high-resolution ERA5 reanalysis dataset. The methodology integrates advanced feature engineering, principal component analysis (PCA), clustering, and classification to delineate and predict regional climate patterns. Nineteen enhanced features are derived from meteorological variables, encompassing temperature statistics, humidity variability, pressure dynamics, wind characteristics, and specialized indices such as aridity and temperature-humidity. Robust scaling and PCA are employed to reduce dimensionality while retaining approximately 95% of variance, followed by K-means and hierarchical clustering to group provinces into distinct climate classes. Classification models, including K-nearest neighbors (KNN), random forest, and gradient boosting, are rigorously evaluated for predictive performance. Results demonstrate that K-means clustering with seven clusters achieves the highest silhouette score of 0.350, while gradient boosting yields the highest mean cross-validation accuracy of 0.771 (KNN 0.762, random forest 0.738). Thirteen visualizations, including correlation heatmaps, PCA scatter plots, dendrograms, and radar charts, provide deep insights into feature interactions and climate class profiles. This framework offers a scalable, data-driven solution for regional climate analysis, with significant implications for environmental planning, agricultural optimization, and policy formulation in China's diverse climatic landscape.
