Some Recent News about Hurricane

Background

Over the past thousand years, tropical cyclones have struck the Earth. Among these, one of the first tropical cyclones ever recorded would have occurred in Western Australia which was around 4,000 BC. But at that point, there was no way of detecting a tropical cyclone unless it hit land or a ship suffered. When satellite images became available in the twentieth century, they are easily detectable. Currently, approximately 80-90 named tropical cyclones are formed on Earth each year. Of these, over half are hurricane-strength winds of 120 km/h or more. All over the world, it is generally considered that a tropical cyclone formed with average winds of 65 km/h. At this stage, it is assumed that a tropical cyclone has become self-sustaining and can escalate without any environmental support. According to a study, published in 2021 in Nature Geoscience, ‘the geographical range of tropical cyclones is likely to expand towards the pole in response to the warming climate of Hadley circulation.’...

Intensity of Hurricane

The intensity of a tropical Cyclone is based on the speed of the wind and on the atmospheric pressure. In order to determine the intensity of the storm, we must understand the relation between the wind and the pressure. For this purpose, the Australian Scale and the Saffir–Simpson Hurricane Wind Scale are being used to measure wind speed to determine storm classification. In 1979, the most severe storm, Typhoon Tip in the Pacific Northwest was recorded. This storm reached a minimum pressure of 871 hPa and the maximum speed of the wind reached 189 mph. The highest sustained speed of the wind was ever recorded at  213 mph in 2015 for Hurricane Patricia. This is the strongest hurricane ever registered in the western hemisphere....

Formation of a Hurricane

To function properly, Tropical cyclones need warm and moist air as fuel. So that, to form a tropical cyclone, the first ingredient is worm ocean water, where rain clouds are being built. In this regard, tropical cyclones form only in tropical regions. Here the ocean is at least 46 degrees C for at least at the top  165 feet below the surface. The wind is the second component of a tropical storm. The wind moving across the Atlantic from Africa to the west supplies the essential component for hurricanes to form in the Atlantic Ocean. Water on the ocean’s surface evaporates (becomes water vapour) and rises as the wind blows over it. Big cumulonimbus clouds are created as the water vapour cools and condenses again into large drops of water as it climbs. It is only the beginning....

Common Regions of Hurricanes

Generally, hurricanes occur in the northeast of the Pacific Ocean, the Atlantic Ocean, the northwest of the Pacific Ocean or in the Indian Ocean. Hurricanes are the largest and most severe storms on Earth. There are many names of Tropical cyclones in different parts of the world. In the Pacific Ocean and China, it is known as Typhoons; in the Atlantic Ocean and in the Caribbean sea it is Known as Hurricane; in the Southern USA and Western Africa, it is known as Tornadoes; in the Northwest of Australia, it is known as willy and in the Indian Ocean, it is known as Tropical Cyclone....

Impact of Hurricane

Animals and plants can be wiped out during hurricanes as a result of devastating winds, flooding, and storm surge.  Animals that depend on these creatures as a food source can die if there is no other alternative source of food.  Beaches are most affected by hurricanes and are eroded when storms hit coasts. Beachfront creatures can be swept away by violent hurricanes.  Furthermore, erosion and sediment deposition typically affect coral reefs. Hurricanes introduce salt water into nearby creeks and freshwater lakes. As a  result, a huge fish died. It also destroys other lake habitats. Hurricanes have the potential to have a significant impact on agriculture. For example, hurricanes produce heavy rains and strong winds which can kill cattle and damage crops.  Building collapse can result in injury and death. But the greatest impacts of hurricanes happen after the storm....

Some Recent News about Hurricane

On October 2022, a destructive hurricane hit on the USA, named Hurricane Ian. At least 66 people have reportedly died in Florida as a result of Hurricane Ian, and four people have been killed in North Carolina in hurricane-related incidents. On September 2022, another devastating hurricane, named Hurricane Fiona rushed towards Atlantic Canada with strong wind and heavy rainfall....

Conclusion

Basically, Hurricane is a type of Tropical Cyclone. It is the most destructive type of natural disaster. It causes destruction to property as well as many life in every year. It has a lot of negative impacts on the ecosystem.  A lot of animals and plants destroy due to this type of tropical cyclone. It also has many negative impacts on the social and economic life of humans. It destroy many infrastructures and properties.  Today, weather satellites help us to track tropical cyclones. Every half an hour, it sends images and weather information from space to understand the possibilities of the formation of a Hurricane. It helps us to take necessary steps to prevent lives from the destruction by the storm....
