作者： ge Lijun

When his masterpieces of engraved block printing were being exhibited, master craftsman Yang Luoshu was nowhere to be seen. At 91 years old, his health kept him from attending the event. But he still insisted on sending a congratu latory video from his village of Yangjiabu in east China＇s Shandong Province. After greet ing visitors to the exhibition, he shared with them his most heartfelt wish：＂I hope that all handmade crafts can be passed down from generation to generation.＂

Low- and Mid-High Latitude Components of the East Asian Winter Monsoon and Their Reflecting Variations in Winter Climate over Eastern China

引用

Atmospheric and Oceanic Science Letters 2012年第3期5卷 195-200页

作者： LIU ge JI Li-Ren SUN Shu-Qing XIN Yu-Fei Chinese Academy of Meteorological Sciences （CAMS） Beijing 100081 China The State Key Laboratory of Numerical Modeling for Atmospheric Sciences and geophysical Fluid Dynamics Institute of Atmos-pheric Physics Chinese Academy of Sciences Beijing 100029 China

The present study defines a low-latitude component (regionally averaged winter 1000-hPa V-winds over 10 25°N, 105 135°E) and a mid-high-latitude component (regionally averaged winter 1000-hPa V-winds over 30 50°N, 110 125°E) of the East Asian winter monsoon (EAWM), which are denoted as EAWM-L and EAWM-M, respectively. The study examines the variation characteristics, reflecting variations in winter climate over eastern China, and associated atmospheric circulations corresponding to the two components. The main results are as follows: 1) the EAWM-L and EAWM-M have consistent variation in some years but opposite variations in other years; 2) the EAWM-M index mainly reflects the extensive temperature variability over eastern China, while the EAWM-L index better reflects the variation in winter precipitation over most parts of eastern China; and 3) corresponding to the variation in the EAWM-M index, anomalous winds over the mid-high latitudes of East Asia modulate the southward invasion of cold air from the high latitudes and accordingly affect temperatures over eastern China. In combination with the variation in the EAWM-L index, anomalous low-latitudinal winds regulate the water vapor transport from tropical oceans to eastern China, resulting in anomalous winter precipitation. These pronounced differences between the EAWM-L and the EAWM-M suggest that it is necessary to explore the monsoons' individual features and effects in the EAWM study.
