    Effects of development of Jinan city on climate are studied. The results show that the difference of the temperature and raining days between Jinan city and rurality is gradually increasing;the sunshine duration,direct solar radiation and global radiation over the city attenuate remarkably,while the sky radiation is increasing gradually.

    Based on the monitoring data for tropical atmospheric and oceanic features,the special climate background for the occurrence of 1994/1995 ENSO event was diagnostically analyzed.Meanwhile,the process and characteristics for the o)nset and development of the ENSO event and its impacts on the world weather and climare conditions were also discussed. These resllts provided detail observed and analyzed facts for the researches on tropical ocean-atmosphere interaction.and also the theory,modeling and prediction for ENSO event.

    An investigation of the torrential rain during June-September,1981-1991 over the middle reaches of the Yellow River is introduced. Using a method of composite analysis,the features of atmospheric circulation of the occurrence of the torrential rain in different circulation pattern are analysed.
    6  Preliminary Study of Orographic Rian Evaluation

    [Abstract](370) [HTML](0) [PDF 2.72 M](610)
    The method and process for evaluated orographic rain based on orographic parameter,sounding data and meteorological factor in the catchment where there are moisture charge around insolated hills are described. Thus the variable of orographic rain is separated from the provision about atmospheric weather system.
    7  The Climate Features of Tropical Cyclone Heavy Rain and Falling Area Forecast in East China
    沈树勤 于波 张菊芳 李昕
    1996, 22(2):33-37. DOI: 10.7519/j.issn.1000-0526.1996.2.008
    [Abstract](843) [HTML](0) [PDF 3.27 M](649)
    The main features of tropical cyclone heavy rain in recent years are shown. Combining thermal parameter with dynamic parameter,the diagnosis analysis of the tropical cyclone heavy rain is presented by the use of integrated and contrast method. The possibility forecast of tropical cyclone heavy rain falling area is given by the numerical weather prediction products.
    8  Lag Correlation Analysis by Stepwise Regression Method
    1996, 22(2):38-39. DOI: 10.7519/j.issn.1000-0526.1996.2.009
    [Abstract](584) [HTML](0) [PDF 1.47 M](661)
    A new lag correlation analysis model is developed with a stepwise regression method. This model gives a simple method to generate predictors which suit to multivariate regression. Computational results show that this model is more objective in periodic predictor selection than general models. All predictors have the same premise of statistic and significance test to predictant.What's more,this model has some resolving power of hidden periodicity.
    9  The Analysis of Physical Feature of Aerosol Particles in Autumn over Shijiazhuang Area
    孙玉稳 段英 吴志会
    1996, 22(2):40-43. DOI: 10.7519/j.issn.1000-0526.1996.2.010
    [Abstract](510) [HTML](0) [PDF 2.56 M](608)
    The daily change of number density of aerosol particles and quality concentration in horizontal and vertical derection are analyzed. The earosol data observated by aircraft is used in convective baundary layer under different weather conditions during autumn in 1990 over shijiazhuang area. The results show that the aerosol particles are of local ones under clear air over shijiazhuang area. The concentration of aerosol particles is from 0. 15×10-9 to 0.85× The characteristic value of spectral distribution N0 is from 1.5×105 to 5.5×105g. cm-3,and λ value is from 13 to 15μm-1 below 4000 meters. The upward transport of aerosol particles is limited,and its distribution occurred discontinuity due to the inversion layer effected.The daily change of aerosol number density in the morning was greater than in the afternoon. The spectral distrbution of aerosol particles was affected for the city effected. The number density of aerosol particles over the city area was higher than that over the rural area.

    The distribution of cloud top temperature is estimated base on the echoes at the top height of the Precipitating stratiform cloud system measured by the 713 type weather radar in Hebei province. The results show thai from 57 percent to 70 percent of cloud top temperature are seedable in the stratiform clouds according to proposed seedability index of cloud top temperature by Grant. In the sametime,based on different attenuated dB values of radan echoes (?Z/?H),the growth case of snow particles with different temperature layers variation is analyzed.
