EXPERIMENT ON THE FORECAST OF CHARACTERISTIC QUANTITIES OF ATMOSPHERIC TURBULENCE BY MESOSCALE MODEL MM5

In nested nonhydrostatic mesoscale model MM5,the characteristic quantities of atmosphericturbulence,i.e.,the standard deviations of the turbulent fluctuated speeds for three directions inPBL are computed by Mellor-Yamada's level 2.5 closure scheme.The magnitudes and the verticalprofiles of these quantities computed from the model are closely connected with temperature andwind speed profiles as well as the type of the ground with a significant diurnal variation,and are inagreement with known magnitudes and regularities in different stratification conditions.Hence themethod in this paper is reasonable and convincible.Their horizontal distribution depends on thehorizontal distribution of the stratification.The method of predicted characteristic quantities ofturbulence from mesoscale model in this paper can be used in the problem of atmospheric diffusionand atmospheric environment.     

斜井成像测井资料处理中地层产状的校正方法及应用

从成像测井图像中直接提取的地层产状,只反映测井仪器坐标系中的结果。对于井眼倾斜的情况,只有进行了井斜校正后,才能获得真实的地层产状。作者推导了成像测井地层产状计算结果的井斜校正算法,并将其应用于苏北大陆科学钻探PPⅡ孔超声成像测井资料处理中,给出了应用实例。     

EXPERIMENT OF QUANTITATIVE MEASUREMENTS OF PRECIPITATION BY USE OF WEATHER RADAR IN THE HUAIHE RIVER BASIN

With the scheme of the variation analysis and Kalman filter,the radar data were adjusted bythe real-time rain gauge data.The accuracy of areal rainfall calculation was improved and theresults can be basically used for flood forecasting.It is concluded that the scheme is suitable in theupper and middle reaches of the Huaihe River.     

对地球质心偏移及板块驱动力的讨论

支持宇宙力参与板块运动的观点,赞同地球质心偏移的论断,但对质心偏移的力源和成因提出不同的看法。数理推导表明,太阳斥力与万有引力常数G的变化综合作用、冰盖在一极的形成与消融等是质心偏移的主要力源。     

油气地表化探指标的统计分类和优选

本文研究了影响趋势面拟合度的主要因素，提出了由参与趋势分析的数据个数n、数据的标准偏差σ和所期望的拟合度c估计最佳趋势面次数k的统计方法。同时还给出了多化探指标下，综合选择趋势面次数的五、c图法。按上述方法，选择趋势面，对我国东部几个地区化探资料处理效果良好，这对于多指标，大数量化探异常的研究有一定的参考价值。     

An analysis of Indian tide-gauge records

The paper presents an analysis of four Indian tide-gauge records. The stations were: Bombay, Madras, Cochin and Vishakhapatnam (Vizag). They were selected because of their reliability. There was no evidence of a monotonic rising trend at all four stations. The test by Mann and Kendall (loc. cit.) showed a rising trend at Bombay from 1940 to 1986 and at Madras from 1910 to 1933. The other records did not reveal a significant trend. The records reveal evidence of long-period cycles (50–60 year period), with shorter cycles (4.5 to 5.7-year period) riding on them. Spectral peaks corresponding to shorter cycles passed a false alarm probability test at 95% level of significance. The peaks were identified by computing periodograms and by maximizing the entropy of the time series. ARIMA models suggest a third order autoregressive model for Bombay and Madras (1953–1986). The remaining records only had a moving average component. Monthly tide-gauge data of Bombay reveal a 13.4-month cycle which was statistically significant. This was close to the 14.7-month Chandler wobble. But, an interaction between a 13.4-month and an annual cycle could not fully explain the observed short period cycles. Finally, the paper summarizes evidence to indicate that a pattern exists between fluctuations of monsoon rain and relative sea level at Bombay.
