报告题目:闪电活动与强降水及台风强度变化的关系

报告人:徐伟新

报告时间:710日下午2:30-4:00

报告摘要:Lightning is not only a severe natural hazard itself but also a major trigger for global wildfires and significant contributor to nitrogen oxides in the atmosphere. Increase of lightning may lead to elevated ozone (greenhouse gas) in the upper troposphere. Many studies suggest that global warming may induce stronger convection and more lightning, therefore, lightning increase is a growing concern.Most importantly, lightning is an excellent indicator of intense convection and closely related to severe weathers including extreme precipitation. However, thunderstorm frequency in China decreases markedly during the last few decades, somewhat opposite to the increasing trend of extreme (hourly) precipitation. Underlying physical mechanisms for thisare still unknown, and fundamental relationships between lightning and extreme precipitationwarrant more research.
