Abstract A simple diagnostic scheme, which combines a low‐pass temporal filter (with an 18‐month cutoff time) with a regular empirical orthogonal function (EOF) analysis, is used to delineate the synchronous evolution of El Nino‐Southern Oscillation‐related (ENSO‐related) modes in various variables of the ocean‐atmosphere system. Based on the causal relation chain of diabatic heating, divergent circulation and rotational flow, the diagnostic scheme extracts ENSO modes from the following data sources: the Pacific sea surface temperature (SST), the past 14‐years (1979–1992) of data generated by the Global Data Assimilation System of the National Meteorological Center, and a 10‐year (1979–1988) general circulation model climate simulation made at the Goddard Laboratory for Atmospheres. The analysis reveals the following: (a) the eigencoefficient time series of the first eigenmodes of selected filtered variables, which explain about 40–50% of their total variance, synchronize with the filtered SST averaged over Area NINO‐3; (b) the spatial structures of the first eigenmodes resemble the ensemble departures associated with ENSO events of these variables from their long term means; and (c) the results show that the proposed scheme can be easily applied to isolate and illustrate the time evolution of ENSO modes which exist in the long term observational database as well as in climate simulations. 相似文献

The presence of Dicynodontia in Sinkiang was first made manifest by the beautiful skull described in the same number of the Bulletin, (see above 563) as Dicynodon sinkianensis sp. nov. Recently, a second skull also collected by 相似文献

The fossil fishes described in the present paper were first discoveredand excavated by Mr. W. C. Pei of the Cenozoic Laboratory, GeologicalSurvey of China, from Choukoutien in 1933. According to my deter-mination they, except one specimen, belong to the genus Barbus of thefamily Cyprinidae, being represented by Barbus szechuanensis Tchang 相似文献

One of the most important results obtained by the Sino-Swedish Expedition led to Sinkiang by Dr. Sven Hedin during the years 1925-1931, has been the discovery, by Professor Yuan, of a rich Permo-Triassic reptilian 相似文献

A post–World War II Japanese business model has changed the cultural production of capitalism globally. Instead of a drive for uniformity, difference is a resource for the supply chains that have come to dominate Asia—and the world. This article offers a pocket history of the model's emergence and explores its implications for the (non)management of labor and natural resources. Heterogeneity and ruin intertwine in the making of supply chain pockets of political economy. Supply chains link precarity and prosperity, as well as varied cosmologies and ways of life, creating difference-in-connection. What we know as Asia reemerges within the linked niches and nodes of supply chains in which all kinds of difference matter and in which, indeed, global connection flourishes through structures for making and maintaining difference. 相似文献
