Witryna12 maj 2024 · The weak signal of the simulated QBO–MJO connection may be due to the weaker amplitude of the QBO than observed, especially between 100 to 50 hPa. This weaker amplitude in the models is seen both in the QBO–related zonal wind and temperature, the latter of which is thought to be critical for destabilizing tropical … Witryna27 lis 2024 · For example, over the tropics there are periodic changes in the direction of winds in the stratosphere, a phenomenon known as the Quasi-Biennial Oscillation …
