Opis:: The article presents characteristics of the position the Asian Giants occupy on the international stage. India and China by partnership and rivalry take advantage of the contemporary economic situation in order to strengthen their role of global leaders. Thanks to the natural resources, demographical potential and complementarity, the economies of the South try to overcome the stagnation and recession period, simultaneously trying to improve the relations with South America. By means of this, they try to move the centre of world economy on the southern part. Moreover, the rivalry between the biggest Asian countries will be mentioned, as well as the structure of trade exchange and political relations between them.

Opis:: The purpose of the paper is to analyze the spatial variability of precipitation in Poland in the years 1981–2010. The average annual rainfall was 607 mm. Precipitation in Poland is characterized by high spatial and temporal variability. The lowest annual precipitation was recorded in the central part of the country, where they equaled 500 mm. The highest annual precipitation totals were determined in the south, equaling 970 mm. The average precipitation in the summer half-year is 382 mm (63% of the annual total). On the basis of data from 53 climate stations, maps were made of the spatial distribution of precipitation for the period of the year and winter and summer half-year. The kriging method was used to map rainfall distribution in Poland. In the case study, cross-validation was used to compare the prediction performances of three periods. Kriging, with exponential type of semivariogram, gave the best performance in the statistical sense. Their application is justices especially in areas where landform is very complex. In accordance with the assumptions, the mean prediction error (ME), mean standardized prediction error (MSE), and root mean-square standardized prediction error (RMSSE) values are approximately zero, and root-mean-square prediction error (RMSE) and average standard error (ASE) reach values well below 100.
