Spatiotemporal feature extraction effectiveness comparison. (a) Short-term feature extraction performance (hourly to daily scales) showing R² = 0.923 for capturing turbulent transport mechanisms. (b) Long-term pattern recognition (seasonal scales) demonstrating R² = 0.847 for seasonal variation identification with attention weight distribution.
