This research presents three case studies of low temperature anomalies that occurred during the winter–spring seasons and their influence on extreme events and crop production. We investigate causes and effects of each climate event and developed prediction methods for crops based on the climate diagnostic information. The first study diagnosed the driven environmental-factors, including climate pattern, climate change, soils moisture, and sea level height, associated with the 2011 great flood in Thailand and resulting total crop loss. The second study investigated climate circulation and indices that contributed to wet-and-cold (WC) events leading to significant crop damage in Taiwan. We developed empirical–dynamical models based on prominent climate indices to confidently predict WC events as much as 6 months before they occur. The final study extends from the second study and predict chronic damage to rice crops from climate change by using a crop simulation model. The long-term prediction of rice growth and yield effectively illustrated both decreases and increases in yield depending on climate scenarios. The three studies are different in location and circumstances but the methodologies can be applied across Thailand, Taiwan, and other areas with similar agroclimatology.

The aim of this diploma thesis is to analyze the criteria of the school class climate quality, to deal with the role of the primary school teacher as a co-creator of the climate, with the requirements that are laid on the teacher and the required proffesional competences. The thesis also deals with analysis of the conditions that create the school climate from the pupils' point of view - especially the development compliance that originates from the dependence on the class composition. Another aim of the thesis is to describe issue of newly-made casses on the grounds of created relationships between the pupils both during and outside the lessons. The methods of educational survey and educational-psychological diagnosis were used.
