The extreme value distribution of 5-min rainfall data at Belgrade     

Unkašević Miroslava 《Theoretical and Applied Climatology》1991,44(3-4):223-228

Summary For practical applications both the parent distribution of rainfall intensities and the distribution of their annual maxima are of interest. The relationship between these two distributions cannot be obtained from classical extreme value theory because of seasonal variation and serial correlation in the data. Mathematical results for the distribution of maxima in m-dependent sequences are presented to illustrate the effect of local dependence on the extreme value distribution. The average number of exceedances in a cluster is an important parameter in the relationship between the parent and the extreme value distribution. For 5-min rainfall data from Belgrade, quantiles of the annual maxima are overestimated by about 10 mm h^–1 if the effect of serial correlation is ignored. This bias can easily be removed by taking the local clustering of large rainfall intensities in a rainy spell into account.With 4 Figures  相似文献

Radioactive and trace element distribution in basaltic rocks of Lower Silesia     

Vladimír Kropáček  Věra Vaňková  Reviewer J. Fiala 《Studia Geophysica et Geodaetica》1985,29(3):290-299

Summary The distribution of radioactive(Th, U, K) and selected trace(Rb, Sr, Ba, Y, Zr, V, Cr, Ni) elements in volcanic rocks from the Opole and Jawor regions of the Lower Silesia has been studied. The behaviour of these elements in the studied rocks indicates that the Lower Silesian volcanic rocks are characterized by less differentiated type than other volcanic rocks of the Bohemian Massif, the Opole rock types probably having a less differentiated character than the Jawor rock types.

Effects of the IMF pro- and anti-sectors in the winter midlatitude ionosphere     

Jan Laštovička  Reviewer L. Křívský 《Studia Geophysica et Geodaetica》1985,29(1):101-104

Summary On the basis of the 1966–73 data, the effect of the difference between pro- and anti-sectors of the IMF is found to be negligible in the winter midlatitude (Central Europe) ionosphere contrary to the dominant effect of this difference in the high-latitude ionosphere found earlier.
