Abstract

Extreme weather events, including heat waves and extreme precipitation, are projected to increase under the fossil fuel intensive scenario Representative Concentration Pathways (RCP ) 8.55. The increased heat waves could increase the formation of ozone concentrations. Extreme weather events on the regional scale were predicted and its local influence on the air quality were studied using the global climate model Community Earth System Model to dynamically downscale to the regional models Weather Research and Forecasting Model and air quality model Community Multi-scale Air Quality under the RCP4.5 and RCP8.5 scenarios. The impact of climate change on PM2.5 was investigated. After using the dynamical downscaling technology, the regional air quality model showed relatively good performance compared with observations. Under RCP scenarios, due to emission reduction, the PM2.5 was projected to decrease across US. The intensity and duration of heat waves in US were projected to increase significantly in particular under RCP 8.5, and the mortality risks due to the heat waves may be an order of magnitude higher than present conditions. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).
