Fig. 3: Atmospheric teleconnections associated with water shortages of the Colorado River.
From: Colorado River water supply is predictable on multi-year timescales owing to long-term ocean memory
Composite maps of annual mean soil water (shaded) and 500 hPa geopotential height anomalies (contours) in observations (left), the ASSIM run (center), and the 1–12 months hindcast run (right) at (a–c) 2 years before, d–f 1 year before, and g–i during waters shortage in the Colorado River basin (i.e., yellow shading in Fig. 1). Anomalies are defined as deviations from climatological means and linear trends are removed in each grid. Contour intervals are ±3, ±6, ±9, ±12, ±15, ±18, and ±21 hPa. Zero contours are omitted and negative values are dashed. Light and dark pinks (greens) indicate the statistical significance at the 90% and 95 % levels with two-side Student’s t-test for soil water (geopotential height) anomalies.
