Hurricanes are hurricanes, violent storms with spiral winds, in which the high-pressure cold winds sway around the low-pressure static winds. The storm then emerges from the water to the ground, losing its speed to contact the land after destroying everything that passes on land. The cyclone moves in curved lines or straight lines. Cyclone rotation varies in each of the northern hemispheres in which the cyclone rotates counterclockwise, while in the southern hemisphere the cyclone rotates clockwise, called cyclones or cyclones Or tropical; because they arise over the seas and tropical oceans in the summer and autumn.
Hurricane parts
The cyclone consists of parts: the center area, which is the eye of the hurricane, and is characterized by calmness. The cyclone wall, dense clouds, thunderstorms, lightning, and heavy rain, is characterized by the cyclone's eye and violent vertical movements.
Types of hurricanes
The types of hurricanes are classified according to the Fujita ladder and are classified according to their speed, destruction and the losses that they leave.
Light Cyclone: It is a first-class hurricane with a wind speed of 133-118 km / h, with minor damage to some of the damage in the plantations, the moving of moving houses, and the destruction of equipment on rooftops.
Cyclone is a second-class hurricane with a wind speed of 118-180 km per hour. Its damage is moderate. It uproots light trees, cracks large trees, overturns cars, uproot tents and break windows.
Strong hurricane: It is a third-class hurricane, with a wind speed of 181-210 km per hour. Large trees break down, break the roofs of buildings, uproot roofs, and overturn cars.
A very strong typhoon: a typhoon of the fourth degree, with winds of 210-250 km per hour, destroying houses, especially roofs, uprooting trees, cutting off power lines, and closing roads.
Heavy Hurricane: Hurricane 5, with winds of 251-350 km / h, destroys houses and land, carrying large pieces over long distances.
A powerful hurricane: a typhoon of magnitude 6, with a wind speed of more than 420 kilometers per hour, has not yet come on the ground, but it has assumed a presumption of computers.
