    The short-range climate prediction of the onset and the intensity of South China Sea summer monsoon are studied. The relationships between the South China Sea Monsoon Index (SCSMI) and the environmental fields, such as 850hPa wind, 500hPa height, SST, OLR, are examined. The possible mechanism of the relationship with the South China Sea Summer Monsoon (SCSSM) is discussed. The anomaly of the SCSMI in winter and the previous environmental fields may be used as a earlier signal to indicate the onset and intensity of SCSSM. Based on the above research results, a concept model is raised for the prediction of onset and intensity of SCSSM. The trial prediction in 1998—2001 got a satisfied assessment.

    Based on the monthly acid rain and meteorological data for recent years in Three Gorge reservoir area, the spatial and temporal distribution features of the intensity and frequency of acid rain are analyzed. By contrasting with relative meteorological elements, it can be found that the intensity of acid rain variation relates to precipitation, wind speed and fog days to a certain extent.
    4  Analysis of Thermal Effect of Environmental Conditions in Shijiazhuang City

    2002, 28(10):28-31. DOI: 10.7519/j.issn.1000-0526.2002.10.006
    [Abstract](854) [HTML](0) [PDF 307.97 K](702)
    By using daily surface air temperature data of China′s 200 stations during 1951~1999,schemes of analyzing temperature extremum are designed. Firstly, a designed quality control procedure is performed for the daily data. Next, the thresholds of extremum are estimated in terms of the 95th and the 5th percentiles. Finally, spatial distribution of temperature extrema over China for 50 years is discussed and a new technique is proposed for detecting extreme events.
    7  Comparison of Data and Product Obtained by TRMM/PR and Hong Kong Radar
    何会中 程明虎 周康军 李曾中
    2002, 28(10):32-36. DOI: 10.7519/j.issn.1000-0526.2002.10.007
    [Abstract](806) [HTML](0) [PDF 422.47 K](698)
    The heavy rainfall occurred at Hong Kong and vicinity on Aug. 23,1999 was caused by typhoon ″Sam″. The rain rate and reflectivity distribution at 1km observed by TRMM/PR and HK radar are compared. Generally,they are consistent. Two methods, i.e. average and best match, are used in comparison. The correlation coefficients obtained from best match method are higher than average method. When the distance from HK radar is less than 100km the coefficient is higher. The difference of reflectivity from PR and HK radar has increased with the distance increasing from radar site. When the reflectivity from PR is less than 20dB the value observed by HK radar is larger. Otherwise, the reflectivity from PR is larger. The difference of reflectivity between the two radars increases when the reflectivity from PR becomes larger.
