Connection between Two Leading Modes of Autumn Rainfall Interannual Variability in Southeast China and Two Types of ENSO-Like SSTA

Figure 5

The difference between positive anomaly year and negative anomaly year: (a) 850 hPa horizontal wind (vector: m·s⁻¹; red vector: through the significance t-test at 90% confidence level) and vorticity (shadow: 10⁻⁵ s⁻¹; dotted part: exceeding the significant test at 90% confidence level), (b) the column-integrated water vapor flux (vector: g·kg⁻¹·m·s⁻¹; red vector: through the significance t-test at 90% confidence level) and its divergence (shadow: g·kg⁻¹·m²·s⁻¹), (c) latitudinal wind, vertical motion (vector, omega multiplied by−100) for cross section along the 5°S–5°N, and (d) meridional wind, vertical motion (vector, omega multiplied by −100) for cross section along the 110°E–120°E shadings are through the significance t-test at the 90% confidence level. The SEC is marked by the rectangle.
