这份报纸论述使在 1990 年代末以后沿着东亚海岸在春天观察的趋势凉下来的表面,与全球温暖趋势相对照。当它与在西北的太平洋并且在春天期间变弱 300 hPa 东方亚洲喷气(EAJ ) 冷却海表面温度(SST ) 同意很好,使趋势凉下来的这表面是能理解的。而且,这冷却现象被显示了与北极海冰盖子的快速的衰落有关(原文如此) 在以前的秋天。原文如此,在以前的秋天的信号能在提高了潮湿的春天和行为继续的北极采购那支持在西伯利亚的增加的雪盖子在春天期间。增加的西伯利亚的雪盖子可能经由强壮的放射的冷却和大规模下降运动赞成冷空气群众的向南方的侵略,它可以在东亚间接地作出贡献到温度的减小。另外,三气候当模特儿那能复制表面冷却在下一十年在春天温度设计在过去的预言的无常观察了的东方亚洲春天很好。
This paper presents the surface cooling trend observed in spring along East Asia coast after the late 1990s, in contrast to the global warming trend. This surface cooling trend is comprehensible as it agrees well with the cooling of sea surface temperature (SST) in the northwestern Pacific and the weakening of 300 hPa East Asian jet (EAJ) during spring. Moreover, this cooling phenomenon has been shown to be related to the rapid decline of Arctic sea ice cover (SIC) in previous autumns. The Arctic SIC signals in previous autumns can continue in spring and act as enhanced moisture sources that support the increased snow cover in Siberia during spring. The increased Siberian snow cover possibly favors the southward invasion of cold air masses via strong radiative cooling and large-scale descending motion, which may contribute indirectly to the reduction of temperature in East Asia. In addi- tion, three climate models that can reproduce well the East Asian spring surface cooling observed in the past predicted uncertainty in the spring temperature projection in the next decade.
