Attribute Analysis of Aridity Variability in North Xinjiang, China

Figure 9

Wavelet coherence between annual AI and meteorological factors in North Xinjiang, China. The black contour lines show the regions of power significant at the 95% level, which are computed based on 1000 Monte Carlo simulations. The cone of influence (black curve) indicates the region without edge effects. The power values are coded from dark blue for low power to dark red for high power, as shown in the right panel on each figure. The vectors indicate the phase difference between the aridity and annual meteorological factors: : in phase; : in antiphase; : leading by 90°; : leading by 90°.
