Section 2: Abstract
Plain Language Summary
The greenhouse gas induced warming increases the water holding capacity of the atmosphere, which likely results in enhanced extreme precipitations. Extreme precipitations and associated flooding often cause significant societal disruption; therefore, it is imperative to study the changes of extreme precipitation under climate warming scenario. Most previous studies have focused on the frequency and intensity changes of extreme precipitation events from a statistical or climatological perspective. However, few studies have investigated the physical response of an extreme precipitation event to future climate warming.
During 19-22 June 2013, an extreme precipitation event happened in Alberta, which brought severe flooding and socio-economic damage to many locations in southern Alberta. This work aims to investigate the physical responses of the 2013 Alberta heavy rainfall event to future climate by conducting high-resolution pseudo-global warming WRF simulations. The control experiment is forced with 6-h European Centre for Medium-Range Weather Forecast Interim (ERA-Interim) reanalysis data; the sensitivity experiment is forced with 6-h perturbed ERA-Interim reanalysis data (i.e., ERA-Interim reanalysis + climate change signals derived from 5 global climate models under the Representative Concentration Pathway 8.5 emission scenario). This poster will present results from the two simulations.
