March 23rd is World Meteorological Day. Many cities across China held various activities on Suday to promote people's awareness of meteorological knowledge as climate change has become a worldwide concern.

Meteorological experts in south China's Guangxi Zhuang Autonomous Region, opened classes to primary school students to promote their awareness of disaster prevention and reduction. An expert is asking what the don'ts are in a thunderstorm.

"We should not hide under the tree, because the thunder will hit the tree and start a fire."

"Don't watch TV. Don't use computers, and don't use cell phones."

In municipalities and provinces like Chonqing, Henan, Jiangxi, meteorological observation stations were opened to the public for people to experience how a weather report is produced, from collecting data to broadcasting on air.

In Xinjiang Uygur Autonomous Region in Northwest China, local meteorological departments showed the public their equipment with the latest technology, such as mobile radar vehicle and mini pilot-less plane.

China has the biggest meteorological observation system in Asia. China Meteorological Administration head Zheng Guoguang says such an advanced system can provide sufficient meteorological service for the 2008 Olympics.

"All the Olympic venues are equipped with meteorological observation stations. At the same time, we have arranged staff members at every Olympic venue to provide related meteorological service."
