Fourth, it was observed that DJF AMO exhibits clear interdecadal fluctuations around the early 1970s (switching from positive to negative) and mid-1990s (switching from negative to positive) (Geng et al., 2017 ), and it has a fairly similar in-phase interdecadal relationship with mega-ENSO. , 2015 ), the warm (cold) AMO might lead to an increased (decreased) epochal winter haze frequency over Beijing and its surroundings by suppressing (facilitating) occurrences of in asiame profile examples situ cold air via a quasi-barotropic planetary-scale Rossby wavetrain emanating from the North Atlantic. However, the actual decreased epochal WHDCock sucking during P2 (corresponding to warm AMO) and increased epochal WHDBlowjob during P1 (corresponding to cold AMO) allow us to speculate that AMO could play a relatively minor role in modulating WHDBj on decadal timescales compared to mega-ENSO. Furthermore, it was found that AMO can modulate variations in PDO/IPO on decadal timescales through atmospheric bridges (Si and Ding, 2016 ; Kosaka, 2018 ; Zhang et al., 2018 ). Therefore, the existence of appreciable interactions between DJF AMO and mega-ENSO, if any, should be ascertained. These issues are deserving of further investigations in future studies.

We are pleased to Zhiwei Zhu and Jian Cao of Nanjing University of information Research and you will Technology getting of use talk and technical advice in the powering the brand new numerical design. I give thanks to the latest unknown writers due to their constructive comments and you will recommendations. Which performs try backed by the fresh new Atmospheric Pollution Command over brand new Perfect Minister Finance (Give Zero. DQGG0104), the National Natural Research First step toward China (Give No.41790471), this new Federal Basic research Innovation (973) program out of Asia (Grant Zero. 2012CB417205), and also the Proper Priority Search System away from Chinese Academy out-of Sciences (Give Zero.

Investigation S1 Shape S1. December–February (DJF) ingredient distinctions out-of sea body heat (SST) (shady, °C) within the months ranging from (a) pre-P1 (1961–1971) and P1 (1972–1996) (pre-P1 minus P1) and you will (b) P2 (1997–2012) and you can article-P2 (2013–2018) (P2 without article-P2) after deleting the latest linear pattern. The fresh red outlines within the (a) and (b) show the latest west Pacific K-profile and also the east Pacific triangle-profile regions, which are deployed inside identifying the fresh new mega-ENSO index based on Wang mais aussi al. (2013).

Figure S2. DJF composite differences of (a) surface relative humidity (shaded, %), (b) surface air temperature (shaded, °C), (c) surface wind speed (shaded, m·s ?1 ), (d) sea-level pressure (shaded, hPa), (e) planetary boundary layer height (shaded, m), and (f) air temperature between 850 and 1,000 hPa (shaded, °C) between years of more and less frequent wintertime haze days in Beijing (WHDBlowjob). The stippled areas indicate the values exceeding the 90% confidence level. The pentagram delineates the location of Beijing. The more (less) frequent WHDBj is defined with a detrended WHDBlowjob value >0.8 (

Figure S3. Brand new climatological-indicate (1981–2010) DJF 500-hPa geopotential level (traces, gpm) and 850-hPa piece of cake (vectors, m·s ?step one ). The new pentagram distills the location from Beijing, therefore the grey shaded area indicates this new Tibetan Plateau.

Contour S4posited DJF defects of (a) facial skin relative humidity (shady, %), (b) epidermis sky temperature (shady, °C), (c) facial skin wind-speed (shady, m·s ?1 ), (d) sea-height pressure (shady, hPa), and (e) heavens temperatures anywhere between 850 and you may step one,100 hPa (shady, °C) getting pre-P1 (1961–1971). The bottom period is 1961–2018.

Shape S5. DJF ingredient huge difference regarding five-hundred-hPa omega (traces, ten ?dos Pa·s ?1 ) inside months anywhere between P1 (1972–1996) and you may P2 (1997–2012) (P2 without P1) after deleting new linear pattern. Thinking which can be high during the ninety% trust height are shady. The new pentagram delineates the region from Beijing.

Profile S6posited DJF defects from SST (shaded, °C) to have blog post-P2 (2013–2018). The brand new red lines show the western Pacific K-figure plus the east Pacific triangle-figure countries, which are deployed when you look at the defining the new mega-ENSO directory centered on Wang mais aussi al. (2013). The beds base several months is 1961–2018.
