Fig. 2: Low-Level Jet leads to summer rainfall over Pakistan.
From: Middle east warming in spring enhances summer rainfall over Pakistan
a Regression coefficients of the absolute vorticity (shading; unit: day−1) onto the normalized Pakistan’s summer rainfall index for all summers from 1979 to 2022. The locations where the regressed vorticity is zero are marked with a red line. The red line represents the position of Low-level jet (LLJ) maxima in summer. b The regression of rainfall amount derived from GPCP dataset (shading; unit: mm day−1) onto the normalized LLJ ___location index in summer during the period of 1979–2022. The dotted areas in both a and b are statistically significant at the 95% confidence level using the Students’ t test.
