Weather expert analysis

Analysis of the Central Meteorological Observatory chief forecaster Zhang Ling said, "ramasun" is uneven path stability, velocity and other characteristics, and strengthened rapidly in offshore. 17th, at 17 o'clock strengthened to typhoon, 18th, at 5 o'clock in the northwestern South China Sea to strengthen as a super typhoon, at 11 o'clock and its Center is located about 115 km South-East of Wenchang city, Hainan Province, on the northwestern South China Sea Sea, maximum winds near the Center has 17 steps (60 m/s), log in at 15:30.

Particularly noteworthy is that "ramasun" also has the landing characteristics of intensity, its strength is extreme, is landing in South China most strong typhoons in 41 years. It is learnt that in 1973 's super Typhoon MARGE, landing centres in coastal areas of Qionghai in Hainan with maximum wind speeds of 60 mph, where the devastating, Qionghai 90% houses had been blown down, reduced to rubble the rubble. According to incomplete statistics, MARGE in Hainan, causing hundreds of deaths.

When defenses focus on: inner harbour vessels, port facilities and coastal towns, villages, and offshore personnel, such as safety of life and property.

In addition, the Typhoon weakened after landfall are still carrying lots of warm, moist air. In its in-depth land Hou, and land over relative cold of air mutual role, in inland often caused storm, and Cloudburst, even King storm, and thunderstorms, and Council to tornado, strong weather, very easy raised mountain flood, and mudslides, and landslide, city village flood, and product flood, and small river library Tang spill dam, and collapsed dam, meteorological disaster and derivative disaster, especially need do related prevention.
