According to the Guangdong provincial meteorological Observatory experts, "ramasun" influence over China's influence in the history of the continent's most powerful Typhoon "Saomai", due to its extreme in the history of Taiwan, Guangdong Province set a new record.

　　The strongest typhoon intensity

It is understood that under the background of El Ni?o outbreaks this year, "ramasun" built into the South China Sea for the Western Pacific, walking and energy savings in just 42 hours from a typhoon into a super typhoon, landed in Guangdong near the Center with gusts up to 60 m seconds, most depressions 91,000 kPa.

Meteorological observatory chief forecaster Lin Liangxun, Guangdong Province, pointed out that "ramasun" strongest typhoon intensity, Guangdong has more than Typhoon recorded extreme values.

　　Landing sites for the most

"Ramasun" landfall in Hainan, Guangdong, Guangxi, respectively, plus landing in the Philippines, there are four landing sites, history. "Lin Liangxun, due to" ramasun "built along the West, Guangdong, Hainan and Guangxi coastal land forms a tangent, where typhoon covers mostly Ocean, conducive to the accumulation of energy, and the land area is small so that it weakened too fast and landed again in favour of it.

　　Emergency the highest level

On July 18, the Guangdong provincial government defense of emergency mobilization orders were issued for the first time. Extreme ramasun, major weather disaster response Headquarters Office of Guangdong Province on July 17, 22:30 will increase its Typhoon emergency response level to the highest level I level, the Guangdong provincial headquarters at 18th, at 10 o'clock in the morning, windproof emergency response rose to level I.
