Moisture Sources by River Basin

There are two figures for each basin. The "Climate" figure shows the climatology of evaporative moisture sources for each basin. This consists of four panes: On top are the 25-year mean moisture source (upper left) and evolution of the mean annual cycle (upper right) expressed in units of kilograms of water per square meter per month. Below are the 308-month time series (lower left) and mean annual cycle (lower right) of sources from the same basin (peach color - corresponds to "recycling"), other large basins that are the main contributors, other land (grey) and open water (pale blue) expressed as a percentage of the total. Note that since rainfall varies from month to month, the lower plots are not an accurate reflection of the variation over time of the quantity of water from any location.

The "Anomaly" figure also has four panes. On top are two sets of four plots showing cases based on extremes of recycling (left) and precipitation (right). The extremes are chosen based on extremes expressed as standard deviations, not water mass. in each set of four plots, the top row is for positive anomalies, the bottom row for negative anomalies. The left column shows a composite for all months with anomalies exceeding two standard deviations; the right column shows the most extreme month. Note that sometimes there are no months available for the composite, and sometimes the extremes are 5, 6, 7 or more standard deviations in magnitude. This indicates that the distribution of monthly precipitation anomalies does not well fit a normal distribution for some basins (particularly in arid regions). The bottom left panel shows the monthly time series of source anomalies - each dotted horizontal line represents one standard deviation, and the time series for each source are offset by one σ for clarity. The table at bottom right shows the correlations (percent) among all combinations of time series shown in the plot. Those significant at the 99% level are printed in bold type.
