报告人：Prof. Balan Nanan

(University of Sheffield, UK)

时间：11月27日15:30-16:30

地点：闻天楼南楼211室

报告内容简介：

Like Earth’s weather space weather sometimes become severe. When it becomes severe it can cause extensive social and economic disturbances in the high-tech society by damaging satellite systems and ground systems. For example, an event such as the Carrington event of 1859 at present times can cause serious damages costing up to 1 to 2 trillion US Dollars.

The seminar will introduce severe space weather (SvSW), suggest a new parameter of geomagnetic storms for space weather applications, address what determines the severity of space weather as experienced by electric power grids and telegraph systems, develop a scheme for forecasting SvSW, and discuss the mechanisms of SvSW.
