Fig. 2: Contrasts of DGPI and its contributing factors.
From: The southward shift of hurricane genesis over the northern Atlantic Ocean
Contrasts of a DGPI, b the cumulative sum from all terms, and the individual contributions from c 850-hPa absolute vorticity (ABS, s−1), d meridional shear of 500-hPa zonal wind (UY, s−1), e vertical pressure velocity at 500 hPa (OMEGA, Pa s−1), and f vertical wind shear (US, m s−1) during JJASON between 2001–2022 and 1979–2000. The blue box denotes the major region of NATL. The black dots indicate statistically significant differences at the 95% confidence level.
