Isolines of the joint probability distribution by the Clayton copula for the annual precipitation in the north and south mountainous regions of the Haihe River Basin. Crosses and dots are measured precipitation in north and south region, respectively. Dashed lines indicate the critical values for dry year (<37.5%) and wet year (>62.5% of the cumulative precipitation) for each region.
