Regressions on the inverse IPT for (A) Walker cell averaged between 5°S and 15°N, (B) Hadley cell averaged between 100°E and 120°E (shaded for the corresponding regressed vertical velocity, units: 10−2 Pa s−1), (C) precipitation (mm day−1), (D) geopotential height (shading; gpm), and horizontal wind (vector; m s−1) at 850 hPa, (E) geopotential height (shading; gpm) at 500 hPa and steering flow (vector; m s−1), (F) geopotential height (shading; gpm) and horizontal wind (vector; m s−1) at 200 hPa. The vector and stippling indicate that regressions are significant at the 0.05 significance level.
