1 Main characteristics of the global, climate from summer of 1986 to autumn of 1988

徐群

1990, 16(6):3-8. DOI: 10.7519/j.issn.1000-0526.1990.6.001

Abstract:
Based on the global climatic system monitoring data , the main characterstics of the global climate from summer o-f 1986 to autumn of 1988 and its contributing factors, as well as main anomalous climate in the world, are summarized. ' .

2 An analysis with isentropic potential vorticity on a cold wave entering the Qinghai-Xizang Plateau

Abstract:
A strong cold wave entering Qinghai-Xizang Plateau during 8-10 January of 1983 is analys.ed by the isentropic potential vorticity (IPV) maps. In this process,the cold air from the stratosphere over the eastern , side of the Urals entered its appearance into the Qinghai-Xizang Plateau through the area of Balkhash Lake and Xinjiang. The weather system developed strongly in the Balkhash Lake area. Its dynamic characteristics -for the development is discussed. The feature and structure of the cold currents and the effects of the plateau are discovered.Therefore it shows that IPV maps are potentially reasonable for the analysis and forecasting of the large scale weather systems.

3 Winter and summer-temperatures in China during the last millenium

王绍武

1990, 16(6):15-20. DOI: 10.7519/j.issn.1000-0526.1990.06.003

[Abstract](530) [HTML](0) [PDF 558.08 K](1091)

Abstract:
It was found that the frequency of the extremely cold and warm events in each of the centeries was closely correlated to the centenary mean temperatures. The extremely cold and warm events were identified with the data since 800 AD. Then, centenary mean winter and summer temperature anomalies were reconstructed.The climatic change during the last millenium was examined.

4 A primary measurement: transmittance of : infrared radiation of CO₂ at room temperature

王松皋 , 张广顺 , 云希俊 , 张红

1990, 16(6):21-25. DOI: 10.7519/j.issn.1000-0526.1990.6.004

[Abstract](1405) [HTML](0) [PDF 394.98 K](1178)

Abstract:
With an experimental device developed recently, the infrared trahsmittance of CO₂ is measured. The primary results are obtained in certain ranges of pressures and optical paths. Compared with the similar research and empirical formulae, abroad, our results are reliable. The empirical coefficients are more reasonable because of higher .resolution of our instrument.
