how is a hurricane formed

Defininghurricane:

how is a hurricane formed ? According to the National Hurricane Center in Miami, it's called Hurricane Tropical Cyclona, which is composed of Atlantic Ocean. Tropical cyclone is a descriptive name given to low-pressure systems developing in the tropics. The surface winds are called tropical low pressure, which does not exceed the maximum speed of 17 meters per second (39 knots at 62.7 km/h per hour at 39 mph/hour). The rate is at least 17 miles per second, given a specific name and is known as a tropical storm. The velocity is called Hurricane (Hurri), which exceeds 33 meters per second (64 knots per hour at 74 mph/hour).


Characteristics of hurricanes:

Tropical formation, namely the oceans of tropical regions near the equator

Their cyclonic formation, namely the wind that they created, revolves around an eye-like center. This movement is in the North hemisphere in the direction of the counterclockwise (east to west), and in the South hemisphere clockwise (west to east).

They're low-pressure systems. The hurricane's eye is always a low-pressure field and the lowest barometric pressures ever recorded were seen in the Hurricanes.

The speed of wind blowing around the center of the storm is at least 74 miles an hour.

How does a hurricane occur?

Hurricanes, warm waters (27 °) C, the air is humid and the combined equatorial winds are located in tropical areas. Most Atlantic hurricanes start with thunderstorms on the west coast of Africa and move towards warm tropical ocean waters. This thunder storm turns into a hurricane in three stages:

Tropical low pressure-swirling clouds and rain, wind speed below 38 miles per hour.

Tropical storm-wind blowing between 39 and 74 miles per hour.

Hurricane-speed winds greater than 74 per hour.

The turning of thunderstorms into a hurricane varies between a few hours and a few days. Although the causes of hurricanes are still not fully known, the following three events must happen in the formation of Hurricane:

The warm moist ocean air is in continuous evaporation-condensation cycle

The strong wind pattern, which unites on the surface, winds unchanged in high places.

There is a difference between the surface and air pressure (pressure gradient) in high places.

The warm and humid air on the ocean surface starts to rise rapidly. As this warm air rises, the water vapor in it intensifies and creates storm clouds and raindrops. Condensation is a heat that is called a hidden condensation temperature. This secret heat warms the air above and causes it to rise. It fills the warm and humid ocean air from the bottom where the rising air is replaced. This cycle attracts more humid air to the emerging storm area than the ocean below and continuously moves hot air from the surface to the atmosphere. The heat exchange from the surface creates a rotating pattern around a center. This cycle resembles the cycle of water flowing down the sink hole.

Wind Patterns:

When moving in different directions, the winds that meet each other, collide on the surface and pushes the warm and humid air up. The rising air strengthens the air that is already upward from the surface, thereby increasing the cycle and speed of the storm. Meanwhile, the strong winds blowing at unchanged speeds at altitudes like 9000 meters allow the rising hot air to move away from the center of the storm, and the hot air continuously moves upward from the surface so that the storm organizations. If the winds in the heights are not at the same speed as every level, so if there are wind shears, the storm cannot be organised and weak.

At the top of the storm center, high pressure on the upper part of the atmosphere also serves to increase the air cycle and the tornado's growth by distancing the heat in the rising air. As the high compressed air is absorbed into the low-pressure storm center, the wind speed increases.

Once the hurricane occurs, it will be monitored in 3 pieces:

• Eye-low pressure cycle fixed Center

• Eye Wall-the fastest and most terrifying winds around the eye

• Rainbelts-Thunderstorms, which are part of the evaporation/condensation cycle that feeds the storm, and are moving out of sight.

The physical size of hurricanes varies. Some storms are very good and only a few wind belts and rain leave behind. Others who are looser can carry hundreds of thousands of miles away from the wind and rain. Hurricane Floyd, who struck the east coast of the United States in 1999, was felt from the Caribbean islands to New England.

The damages of Hurricanes:

Hurricanes leave a large amount of rain in the land to build floods, even inland areas.

Very strong winds give structural damages; It rips the trees from the root, reverses the cars, causes waves to grow in the sea and can cause major damage to coastal areas.

The prevailing winds of the hurricane push the wall of water in large quantities called storm waves. If this is combined with the Med (rising water) event, it leads to large water flooding and damage to the shore.

Hurricane winds often create hoses and can also give extra damage.

Hurricane Categories:

Category 1wind speed 74 miles per hour between 95 miles per hour (119 km with 153 km). The wave brought together is above normal, between 1.2 and 1.5 m. Little or no structural damage. Category 2wind speed 96 mph to 110 miles per hour (155 to 177 km per hour). Wavelength between 1.8 m and 2.4 m. Trees are overthrown, there's damage to the roofs. Category 3wind Speed 110 mph to 130 miles per hour (ranging from the distance of a boat at a normal speed to the difficulty of a day). The houses have structural damage, serious water flooding occurs. Category 4 wind speed 131 miles per hour with 154 miles and wavelength of 4m to 5.5 m. Dangerous water raids in internal cuts, roofs flying, large structural damage. Category 5 wind speed over 155 miles per hour, wavelength over 5.5 meters. Very dangerous water flooding, especially in wood structures are severely damaged.

Starting from Category 3, hurricanes in the violent areas of 4 and 5 lead to severe damage and loss of life in large fields, agricultural areas and large/small cattle.

How to be monitored:

Hurricanes are primarily looking at visual indicators, namely clouds and their return patterns. More technically, the radar and Doppler radar and the data obtained by measuring rainfall, wind speed and precipitation amounts are being made estimates. In addition, there are estimates of heat variations and cloud heights with infrared rays.

Hurricane names:

After the Second World War, the Hurricanes, which were always referred to as male names, were subsequently given the names of women in alphabetical order. This was continued by the end of the 1970s, when the women's associations responded to the Hurricanes, a male female name was given. Nowadays, more than human names are called Delta, Epsilon, Zeta.
