2015年10月9日 · The EAWM influences MJO via the feedback effect of convective heating, because the strong northerlies of EAWM can enhance the ascending motion and lead the convection to be strengthened over the equatorial western Pacific by reinforcing the convergence in the lower troposphere.

2022年12月2日 · Based on Season-reliant Empirical Orthogonal Function (S-EOF) analysis, this study shows that the subseasonal strength reversal of the EAWM (SR-EAWM), featuring a weaker (or stronger) EAWM in early winter (December) and a stronger (or weaker) EAWM in late winter (January–February), is a distinct leading mode of the month-to-month variation of ...

Abstract: This paper presents a concise summary of the studies on interdecadal variability of the East Asian winter monsoon (EAWM) from three main perspectives. (1) The EAWM has been significantly affected by global climate change.

2021年6月14日 · The East Asian winter monsoon (EAWM) is one of the most important climate systems during boreal winter. It has a large meridional extent and provides a vital bridge between the mid-to-high latitudes ...

2023年9月1日 · The Madden–Julian Oscillation (MJO), an important atmospheric 30–60-day oscillation in the tropics, is a crucial predictor of the intraseasonal climate over East Asia (He et al., 2011; Jia et al., 2011; Li et al., 2020; Song and Wu, 2019; Stan et al., 2017).

In this study, we illustrate that the subseasonal variability of precipitation over the East Asian Winter Monsoon (EAWM) region is not only closely tied to activity of the Madden-Julian Oscillation (MJO) over the Indian Ocean, but also linked to precipitation and temperature extremes worldwide, influenced by a circumglobal Rossby wave-train alon...

2020年2月5日 · The East Asian winter monsoon (EAWM) is one of the most active atmospheric circulation systems in the boreal winter (Wang and Fan, 2013). Based on the previous studies, the EAWM has great impacts on the weather and climate over East Asia, including strong cold events and snowstorms (Wang et al., 2017; Zhou et al., 2017, 2018; Wang and Zhou, 2018).

2018年9月1日 · The MJO and the BSISO influence monsoon onsets and high-impact weather events, such as precipitation extremes. A report using the S2S hindcast dataset showed models are capable of forecasting the probability of the Australian monsoon active episodes as a function of the MJO phase.

The strong EAWM causes the intensity of MJO to increase, and the eastward propagation of MJO to become more persistent. MJO activities over the equatorial western Pacific have different modes.

2019年1月1日 · We investigate the relationship between the wintertime PM 2.5 concentration in Beijing from 2005 to 2016 and the East Asian winter monsoon (EAWM) strength based on PM 2.5 observations and the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis data.
