The Guy Carpenter Asia-Pacific Climate Impact Centre (Asia-Pacific region as well as on a global scale. "This year's projects focus on understanding the variations driving weather phenomena in the Asia-Pacific and around the world," said Professor tropical cyclones. One study on cyclone patterns showed a possible decrease in tropical cyclone landfall intensity in the Guangdong province, but an increase in the Zhejiang province. Research on interdecadal change in South China Sea tropical cyclone frequency is related to the sea-surface temperature difference between the North Indian Ocean and the western North Pacific. • Global Circulation: Several studies on global circulation were included in the 2013 GCACIC program. One research project explored the impact of the cold tongue El Niño and the warm pool El Niño on tropical cyclones over the South China Sea from 1965 to 2010. Another demonstrated the great discrepancies in annual cycles of moisture supply, specifically how the variation in regional precipitation over southeast and southwest China strongly depends on externally imported moisture, rather than local evaporation. • Modeling & Prediction: Asia-Pacific cities and around the world. • Air Quality: This year's report also highlights GCACIC's keen attention to the study of air quality, with research focusing on areas such as black carbon, greenhouse gas concentrations, and air pollution forecast modeling. In order to investigate the public's exposure to traffic pollution, an experimental study was executed in Central, a developed business district in Hong Kong. The study examined the impact of traffic volume and composition on the air quality and pedestrian exposure in the area, with the goal of providing insight on targeted and cost-effective emission control and air quality strategies. • Climate Change: Finally, the annual report also details this year's research on climate change, specifically examining heat waves and East Asian jet streams. High temperature extremes have received increasing attention due to their rising impacts on human mortality, regional economies, and impact on affected ecosystems. This study examines the validity and effectiveness of modeling summer hot spells in China. "here.
