Diurnal Variations in Summer Precipitation over the Yellow River Basin

Figure 3

Correlation fields between the monthly mean precipitation (units: mm) acquired from daily rain gauge data over the YRB and the monthly mean column-integrated water vapor transport (units: g·m⁻¹·s⁻¹) in the summer months during the time period 1961–2010. The shaded colors represent the areas with correlations greater than the 90% confidence level. The gray area denotes the Tibetan Plateau (TP) terrain. The green box contains the entire YRB region. The black box in the bottom right-hand corner shows the South China Sea islands.
