What is the difference between a hurricane, tsunami and typhoon
• What is the difference between a hurricane, tsunami and typhoon
These natural phenomena have something in common: they periodically bring a person a lot of trouble. But there are also many differences.
Hurricane - the wind, whose speed exceeds 120 km / h (33 m / s). If it reaches 180 km / h (50 m / s), it is considered a very strong hurricane. At a certain point clouds may temporarily dissipate, but it is only the calm before the storm. His so-called "eye of the storm." Seen this phenomenon, probably, almost all. At least in the picture Ivan Aivazovsky's "The Ninth Wave". After a short respite, strong wind starts again, and the rage he can tens of hours.
In meteorology and hurricane and typhoon are called cyclones. Although still there is a difference between the phenomena, and it is in power. It can be said that the typhoon - is gradually developing hurricane.
Typhoons, turning into hurricanes occur most often between the coast of Asia, the equator line and the date is changed, that is conditional line on either side of which local time is different for a day. It runs from pole to pole. As an example we can recall Typhoon "Haiyang", which in November 2013 began with a storm in Micronesia, and came to the Philippines have already Hurricane.
typhoons peak in the period from May to November. One of the conditions - high temperature of the water in the ocean: +30 ° C. Then the warm air from the water in contact with the top cooling air masses, creating clouds. Precipitation transfer heat to the atmosphere. Facing each other, the air masses at different temperatures to form a low pressure region, which becomes the place hurricane or typhoon birth.
Thus, the boundary between the natural phenomena is very thin. With the tsunami as they are united except high speed.
The tsunami called the long and high waves. They arise due to the earthquake - both underwater and offshore, when the ocean bottom crustal plates shift dramatically. Unlike the conventional wave, a tsunami affects the water from the bottom to the ocean surface. Approaching the coast, the distal front going wave catches, which at that time slows down and rises to 10 and even 50 meters. MOVE a water bank is at a speed of 650-800 km / h, and the velocity is directly dependent on the depth of the ocean place. Usually there will be several such waves, but they come at once, but at intervals of two to three hours. And the same time to cause considerable damage.
