Fig. 7From: Seasonal march patterns of the summer rainy season in the Philippines and their long-term variability since the late twentieth centuryTime-latitude cross section of the pentad mean geopotential height and zonal and meridional components of the wind fields at the 850 hPa level averaged for the years classified in C1 and C4. The figures in the left column indicate geopotential heights for C1 (a) and C4 (b) and the anomalies between C4 and C1 (c). The figures in the middle and right columns indicate zonal and meridional components of the wind field for C1 (d, g) and C4 (e, h) and the anomalies between C4 and C1 (f, i), respectively. The colored grids in c, f, and i indicate the significant anomalies at the two-sided 90% level according to Student’s t testBack to article page
