Association of the pre-monsoon thermal field over north India and the western Tibetan Plateau with summer monsoon rainfall over India

In this paper, interannual variability of tropospheric air temperatures over the Asian summer monsoon region during the pre-monsoon months is examined in relation to Indian summer monsoon rainfall (ISMR; June to September total rainfall). For this purpose, monthly grid-point temperatures in the entire troposphere over the Asian summer monsoon region and ISMR data for the period 1949–2012 have been used. Spatial correlation patterns are investigated between the temperature field in the lower tropospheric levels during May over the Asian summer monsoon region and ISMR. The results indicate a strong and significant northwest–southeast dipole structure in the spatial correlations over the Indian region, with highly significant positive (negative) correlations over the regions of north India and the western Tibetan Plateau region – region R1 (north Bay of Bengal: region R2). The observed dipole is seen significantly up to a level of 850 hPa and eventually disappears at 700 hPa. Thermal indices evaluated at 850 hPa level, based on average air temperatures over the north India and western Tibetan Plateau region (TI1) and the north Bay of Bengal region (TI2) during May, show a strong, significant relationship with the ISMR. The results are found to be consistent and robust, especially in the case of TI1 during the period of analysis. A physical mechanism for the relationship between these indices and ISMR is proposed. Finally the composite annual cycle of tropospheric air temperature over R1 during flood/drought years of ISMR is examined. The study brings out the importance of the TI1 in the prediction of flood/drought conditions over the Indian subcontinent

Pre-monsoon Zonal Wind Index over Tibetan Plateau and sub-seasonal Indian summer monsoon rainfall variability

In this paper, by using the Principal Component Analysis (PCA) technique monthly zonal wind indices over Tibetan Plateau (25°N-45°N, 75-105°E) (TP) at 200 hPa have been constructed for the period 1948-2006. These indices are referred as Tibetan Zonal Wind Index (TZWI). The relationship between the TZWI and Indian summer monsoon rainfall on monthly basis has been studied by the correlation analysis. From the analysis, it is observed that pre-monsoon months (April and May) of TZWI show the significant inverse relationship with June and July rainfall over India respectively. The study may be useful for forecasting rainfall activity in June and July months, which are crucial months from the agricultural point of view

The work of Josef Váchal in art education at the elementary school

The thesis deals with the art of the modern Czech painter and graphic artist Josef Váchal and follows up its use in creative activities at primary school. The theoretical part is devoted to a detailed analysis of Váchal artistic development and brief psychological study of his personality. It also reflects the creation of other artists, whose artistic expression tends to be close to Váchal works. In fine the thesis follows the possibilities of use of artistic work in art education at the elementary school. The practical part introduce the art education project, inspired by works of Josef Váchal, and documents its complex realization at the elementrary school in Borové Lady with the final reflection
