2019年6月10日 · The Quasi-biennial Oscillation (QBO) is a tropical, lower stratospheric, downward propagating zonal wind variation, with an average period of ~28 months. The …

The quasi-biennial oscillation (QBO) is a quasiperiodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 28 to 29 …

2022年9月9日 · The quasi-biennial oscillation (QBO) is a quasi-periodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a …

2021年10月14日 · In late 2021 the QBO is in the easterly (negative) phase. It is not clear how the QBO influences weather at the surface, but when we sort the climatology of weather variables …

2022年12月12日 · In terms of the CEOF-based phase division, the QBO shows a strong modulation on the Arctic Oscillation and Madden–Julian Oscillation activities. This study …

2018年6月13日 · The QBO phase space (Fig. 2) shows the amplitude of P 1 (abscissa) versus P 2 (ordinate) for each month of the time series, and forms an approximate circle around the …

phases of the QBO, where the QBO phase is defined by the 40-hPa equatorial wind. Easterly anomalies are light blue, and westerly anomalies are pink. In the tropics the contours are …

2022年7月19日 · QBO westerly (W) and easterly (E) composites are then segregated by the phase of ENSO. Two pathways are described by which the QBO mean meridional circulation …

2025年1月1日 · Over the Pacific sector, an anomalous high (low) appears during the easterly (westerly) QBO phase, 51 which imprints the QBO signal to the Asia-Pacific sector. It has …

The results show that the quasi-biennial oscillation (QBO) in the tropical stratospheric CO mixing ratios has a phase change at 30 hPa. The results from a chemistry-climate model show that …
