Abstract:
Last decades of the 20th and beginning of the 21st centuries show significant increase in frequency and severity of droughts in the Czech Republic (CR). Their impacts on society and nature require a change in their study from descriptive paradigm to deeper understanding of the droughts occurrence with respect to their causes and identification of physical mechanisms. Of particular interest are the influences of climate forcings, their combined effects and final impacts due to atmospheric circulation. Analysis of droughts during past 515 years based on dendrochronological and documentary data, instrumental records and model simulations will findtheir typical features, forcings and their combinations contributing to delimitation of the onset, course, severity and end of the short-term, medium-term and long-term droughts. Mechanisms of detected drought predictors will be studied on past drought events. This will help to find and deeper understand physical mechanisms and links influencing droughts in the CR under the recent climate change.
