Atmospheric triggering conditions and climatic disposition of landslides in Kyrgyzstan and Tajikistan at the beginning of the 21st century

Abstract. Landslide is a major natural hazard in Kyrgyzstan and Tajikistan. Knowledge about atmospheric triggering conditions climatic disposition of landslides Tajikistan limited even though this topic has already been investigated thoroughly other parts the world. In study, newly developed, high-resolution High Asia Refined analysis version 2 (HAR v2) data set generated by dynamical downscaling was combined with historical landslide inventories to analyze that initialized The results indicate crucial role snowmelt landslide-triggering processes since it contributes initialization 40 % events. Objective thresholds for rainfall, snowmelt, sum rainfall (rainfall + snowmelt) were defined. Thresholds defined have best predictive performance. Mean intensity, peak accumulated amount events show similar Using entire period better performance than just considering up occurrence. annual exceedance maps derived from regional snowmelt. depict added value susceptibility mapping. reported study highlight potential products climate models prediction.
