Outline

3WMO Cg-XVI Side Event – 17 May, 2011

Space weather refers to the short-term variations in space environment that affect space- or ground-based technological system, and in the worse case, endanger human.

Intensive space weather storm could pose a wide range of hazards to human activities.

Space Weather and its Impacts

– Solar flares may disturb the ionosphere, resulting in degraded communication and navigation quality

– Solar energetic particles could damage the equipment of spacecraft

– Solar radiation effects on human being, effecting all cells, and breaking DNA

– Geomagnetic storms can generate GIC in power grids, and disturb spacecraft magnetic attitude control

– Themospheric disturbances may change the orbit, attitude and life of spacecraft

4WMO Cg-XVI Side Event – 17 May, 2011

It is acknowledged in that space weather impacts humna activities and, similar to the weather and climate, a monitoring and forecasting operation system of space weather is needed to guarantee the further development of our society.

Space Weather Monitoring and Forecasting

In 2002, CMA was authorized by the National Council to establish the National Center for Space Weather (NCSW), assigned to the National Satellite Meteorology Center.

Missions of NCSW are:To develop the ground- and space-based space weather observation system;To provide monitoring and forecasting products and services for space weather users;To steer development of the space weather and relevant disciplines;To participate international cooperation on space weather hazards warning and mitigation.

5WMO Cg-XVI Side Event – 17 May, 2011

The ground-based space weather monitoring network has been expanding in China.

About 20 stations are used to monitor the solar

activities, ionospheric and upper atmospheric

disturbances.

More than 500 GPS/MET stations in CMA are

available for routine TEC map product.

It is our mandatory to increase public awareness and education.

CMA currently delivers daily, monthly, and annual monitoring and forecasting products and services to users through hard-copy bulletins, internet, phone, SMS, e-mail, public media, etc.

Public Awareness and Education

CMA also provides special services for important customers, including Shenzhou, ChangE, Beidou missions and State Grid, etc.

9WMO Cg-XVI Side Event – 17 May, 2011

In CMA, the application-oriented research and technology development related to space weather provide significant support to operations.

Space Weather Monitoring and Forecasting

10WMO Cg-XVI Side Event – 17 May, 2011

Human activities are extending into space and becoming

vulnerable to space weather hazards;

Space weather impacts are both regional and global, Sharing

monitoring recourses and forecasting products and services;

Comprehensive international cooperation is necessary for the

mitigation of the societal and economic impact of severe space

weather event.

Global Cooperation on Space Weather

As the 24th solar maximum is approaching, we all need to make a good preparedness together for possible space weather hazards!

11WMO Cg-XVI Side Event – 17 May, 2011

The potential loss due to space weather hazards could be mitigated

by the reliable monitoring, forecasting and service system;

Space weather spans national boundaries, and needs the effective

international cooperation;

As the natural extension of meteorology, space weather could be and

should be the integral component of “weather”;

CMA will continue to fully support the space weather activities of

WMO.
