Using 30 years of daily fields (1993--2022), we compute detrended fluctuation/cross-correlation metrics over 5--50-day scales at every grid: the Hurst exponent ($H$), the cross-Hurst exponent ($\\lambda$), and the DCCA coefficient ($\\rho_{DCCA}$). Significance is assessed with iterative-AAFT surrogates and Benjamini--Hochberg false-discovery-rate control.
