North Atlantic and Pacific Quasi-Stationary Parts of Atmospheric Rivers and Their Implications for East Asian Monsoon Onset
International audience Using a global space-time diagram of column water vapor (CWV) at 30° N latitude from daily reanalysis data, we find two quasi-stationary parts of atmospheric rivers (QSARs) that feature locally enhanced CWV and evolve from the Eastern Pacific/Atlantic basins in the winter to t...

International audience Using a global space-time diagram of column water vapor (CWV) at 30° N latitude from daily reanalysis data, we find two quasi-stationary parts of atmospheric rivers (QSARs) that feature locally enhanced CWV and evolve from the Eastern Pacific/Atlantic basins in the winter to the Western Pacific/Atlantic in the summer. East Asian Summer Monsoon onset coincides with the time CWV in the Pacific QSAR first exceeds 40 mm, which also typically occurs just before it makes landfall.
