These storms go around like a wheel. They have wind speeds of 60 kph or more. They can be very destructive.
When scientists discover a true hurricane, they give it a name. They can use either a man’s or woman’s name. Why should hurricanes have names? The names make it easier for people to keep up with information about a hurricane and its dangers.Tropical CyclonesA brief introduction of tropical cyclonesHow and why to name a hurricanesThe 2nd Skill : Skimming for General idease7d195523061f1c0d318120d6aeaf1b6ccceb6ba3da59c0775C5DE19DDDEBC09ED96DBD9900D9848D623ECAD1D4904B78047D0015C22C8BE97228BE8B5BFF08FE7A3AE04126DA07312A96C0F69F9BAB7002160E556FB8050B6B0CEA014610BCECF9F367F15CB9D950936CDE4380A25E9696BA2099BB4B03A99915B16D6F18264F3D0955B6700EBE0The 3rd Skill :Scane7d195523061f1c0d318120d6aeaf1b6ccceb6ba3da59c0775C5DE19DDDEBC09ED96DBD9900D9848D623ECAD1D4904B78047D0015C22C8BE97228BE8B5BFF08FE7A3AE04126DA07312A96C0F69F9BAB7002160E556FB8050B6B0CEA014610BCECF9F367F15CB9D950936CDE4380A25E9696BA2099BB4B03A99915B16D6F18264F3D0955B6700EBE0The 3rd Skill : Scanning for informationScanning for numbers The idea of the Red Cross came to Henri Dunant, a Swiss banker, in 1859.
