Tropical Storm Nate has intensified to hurricane and is now threatening US coast. According to US Hurrikanzentrums stormed, cyclone at peak speeds of more than 128 kilometers per hour above Gulf of Mexico. On Saturday or Sunday he should meet again in New Orleans on land.
In states of Louisiana and Mississippi, state of emergency was declared. The Louisiana authorities ordered evacuation of several islands and coastal areas. Also Ölbohrinslen in Gulf were evacuated. In Mississippi, emergency shelters were prepared and buses were provided for ride re.
Nate cost at least 22 people in Central America. Most of dead were in Nicaragua.Hurricanes, typhoons and cyclones and hurricanes
As a hurricane , a heavy storm from strength 12 is called Beaufort. They reach wind speeds of at least 64 knots. That's almost 120 kilometers per hour.
hurricanes, typhoons and cyclones are tropical cyclones, salient feature of which is that y obtain ir energy from tropically warm sea. At water temperatures of upper 50 meters of more than 26.5 degrees Celsius slowly evaporates a lot of moisture, which condenses during ascent in atmosphere and releases its heat energy quickly to air masses – and propels storm.Hurricane and Typhoon
In Atlantic, North and South Pacific, tropical cyclones are referred to as Hurricane s, and in Asian region y are called Typhoons.
Hurricanes and typhoons are large-scale structures, whose imposing cloud vertebrae often reach a diameter of 200 kilometers and are shifted from Earth's rotation to rotation. If a hurricane or typhoon loses contact with sea – so to speak ashore – it loses its energy supply and weakens. By definition, a tropical Storm will only become a hurricane or typhoon when it reaches wind power 12 or more (118 km/h).Cyclone
Cyclone is name for tropical cyclones in Gulf of Bengal and Indian Ocean. Such storms can stir up several meters of high waves, which eventually hit land in area of Bangladesh, Myanmar or India. As a result, Cyclones cause great devastation, because y mostly hit land in particularly shallow regions. This can lead to flooding to interior, as shallow transitions from Delta River to sea offer little protection for people and buildings.Tornadoes
Tornado es, on or hand, are much smaller and are characterized by ir spiral shape . They arise above mainland – especially in USA – when hot air rises under a thunderstorm cloud and wind n turns into a whirlpool. Below cloud it becomes visible as a tube.
Tornadoes can reach speeds of up to 500 kilometers per hour. The undertow of tornado sweeps everything into air, which is wind spiral in way.
