Witryna13 mar 2024 · Quarterly Journal of the Royal Meteorological Society. First Published: 04 May 2024. The Quasi-Biennial Oscillation (QBO) of tropical stratospheric winds is observed to affect other regions of the atmosphere including the Northern Hemisphere stratospheric polar vortex, the North Atlantic Oscillation, and the Pacific-sector … Witryna27 lis 2024 · The impact of the quasi-biennial oscillation (QBO) on the surface air temperature (SAT) in the Northern Hemisphere extratropics is investigated. It is found that the QBO, defined as 70-hPa zonal wind in the deep tropics, is negatively correlated with the SAT over the western North Pacific in February and March.
