    1994, 20(5):3-9. DOI: 10.7519/j.issn.1000-0526.1994.5.001
    [Abstract](355) [HTML](0) [PDF 251.34 K](379)
    The recent progress in the upper-air observational techniques at home and abroad are summarized.The topics of discussion include:various sensors and circuits of radiosonde,various wind-finding equipments,measuring accuracy,automatization and economic effectiveness.
    2  A Study on the Bioclimatic Classification of China Based on Man
    张苏平 张文
    1994, 20(5):10-15. DOI: 10.7519/j.issn.1000-0526.1994.05.002
    [Abstract](338) [HTML](0) [PDF 196.40 K](365)
    In order to study the synthetic effect of temperature,humidity,wind speed and solar radiation on human thermal sensation,a human bioclimatic classification is worked out by means of effective temperature and wind-chill index.Climatic data of 657 weather observatories for last 30 years of the country are used.The results show that the whole country can be generally divided into 27 bioclimatic areas in winter and 20 bioclimatic areas in summer. The classification'is of important reference value for human activities such as tourism, settlement,urbanization,military activities etc.
    3  Multi-Steps Forecast Model with Principal Component of Mean Generating Function by Replacement of Information
    李祚泳 张辉军
    1994, 20(5):16-19. DOI: 10.7519/j.issn.1000-0526.1994.5.003
    [Abstract](381) [HTML](0) [PDF 119.05 K](371)
    A method of data analysis of temproal sequences,based on the replacement of new-old information of restrictive memory with lapse of time is developed. This appraoch is based on the modelling of the principal component analysis for the prior L square matrix of period extrapolation matrix Of mean generating function only,with a few principal components inclouding main information of temporal sequence.The scheme is applied to the multi-step forecast of annual meantemperatures of 28 cities in Sichuan,and the relative errors between forecast and real values are not more than 14%,and it is shown that the scheme is effective for the multi-step forecast of temperature.
    4  Relationship between Meteorological Elements and Acid Rain and its Sources at Xiamen City
    俞绍才 蔡小平 陈小江 陈泽面
    1994, 20(5):20-23. DOI: 10.7519/j.issn.1000-0526.1994.5.004
    [Abstract](412) [HTML](0) [PDF 135.49 K](396)
    According to the monitoring results of spring rain,mold rain and typhoon rain at Xiamen from 1983 to 1991,relationships among the acidity of every type of rain and meteorological parameters are studied by analyzing the monitoring data of meteorological parameters of every rain event.The contributions of long-transportation sources and local sources of pollutants to the formation of acid rain at Xiamen are estimated as well.
    5  The Results of Field Comparison of the Remote Meteorological Observing Stations
    郭锡钦 曾书儿 王金钊
    1994, 20(5):24-27. DOI: 10.7519/j.issn.1000-0526.1994.05.005
    [Abstract](603) [HTML](0) [PDF 118.26 K](373)
    The field experiment results of three prototypes of AWS are described.These prototypes submitted a tender and had been preliminary selected by CMA. The experiment shows that under normal conditions,the observing accuracy could basically meet the requirement of CIMO for AWS.Their average vaines for ten days and for a month have no obvious differences with manual observation. But the stations failue often appeared in operation. So that they cannot be used in professional work.The improved prototypes are being tested in field stations now.
    6  Two Graphs of the Relationship between Rainfall and Its Duration and Area
    1994, 20(5):28-32. DOI: 10.7519/j.issn.1000-0526.1994.05.006
    [Abstract](383) [HTML](0) [PDF 161.73 K](390)
    In order to help weather forecasters and hydrorological designers to analyse and forecast the characters of the rainfall,two graphs are contributed. These graphs are concerned about two fomulas got from a theorical analysis,verified by statistical test and used commonly and practically.One of the graph concerns the relationship between rainfall and its duration,the other concerns the rainfall and its area.
    7  GMDH for Forecasting Wind-Velocity
    潘长明 叶卓文
    1994, 20(5):33-35. DOI: 10.7519/j.issn.1000-0526.1994.05.007
    [Abstract](287) [HTML](0) [PDF 126.44 K](405)
    The group method of data handling(GMDH)is used to forecast wind-velocity at eight o'clock each day within three days for the middle and western areas of Bobal sea in Feb. 1991.It'saccurate rate is higher.
    8  The Temperature Change and Its Influences on Agricultural Production for the last 40 Years China
    高素华 潘亚茹 郭建平
    1994, 20(5):36-41. DOI: 10.7519/j.issn.1000-0526.1994.05.008
    [Abstract](589) [HTML](0) [PDF 245.62 K](415)
    The spatial and temporal distribution of mean annual air temperature,the temperature in the coldest and the hottes month in tecent 40 years and the change of temperature departure field in rach decades are analused with the observations at 350 stations well-distributed mostly cover the country from 1951 to 1990.And the influence of temperature change on agricultural production is analysed
    9  Multi-Analysis of Wenzhou Citrus Qualityat Wuxian County,Jiangsu Province
    1994, 20(5):42-45. DOI: 10.7519/j.issn.1000-0526.1994.05.009
    [Abstract](400) [HTML](0) [PDF 151.89 K](363)
    Double screening multiplicity stepwise regression has an obvious advantage in the regressive type analyst'between the multiple arguments and depelldent variables which are interrelative and interactive.There is a coupling relation between orange quality and weather-factors. The application of double screening multiplicity stepwise regression to the analysis of the weather-factors which has an effect on the orange quality is effective. Such weather-factors as light,tempeature and water,esp. the fiEst two,all have an effect oil the orange quality.The effect of multiple-factors is more obvious than that of single-factor.
