Destruction caused cyclones

Every disaster comes with lots of destruction and its after effects impact adversely on lives, property of the human existence and it will take a considerable time to recover that loss. One of the catastrophes is the cyclones and it comes with lots of destruction with it. Knowing its nature and condition , through applying various technologies , prediction of its timing and severity may help us to save lives and property or we can take certain measures to prevent its adverse effect. So, In this article

Introduction

A low-pressure area characterized by rapid and frequently damaging air circulation is what generates cyclones. Storms and unfavourable weather are frequently present during cyclones. In the Northern hemisphere, the air moves anticlockwise, whereas in the Southern hemisphere, it moves clockwise. Extra tropical cyclones, sometimes known as temperate cyclones, and tropical cyclones are the two categories under which cyclones fall. The name “cyclone” comes from the Greek word “cyclos,” which means a snake’s coils. Henry Peddington came up with the term because tropical storms in the Arabian Sea and Bay of Bengal resemble coiled sea serpents.

The World Meteorological Organization (WMO, 1976) refers to weather systems with winds greater than “Gale Force” as “Tropical Cyclones” (minimum of 34 knots or 63 kph). Tropical cyclones are the offspring of the ocean and atmosphere and are propelled by heat from the ocean as well as high planetary winds, easterly trade winds, temperate westerlies, and their own intense activity. Cyclones in India are categorized by: Wind speed, storm surge intensity and exceptionally heavy rainstorms.

Cyclones are given many names in different regions of the world- Typhoons are called cyclones in the China Sea and Pacific Ocean; hurricanes are called cyclones in the Caribbean Sea and Atlantic Ocean; tornadoes are called cyclones in the Guinea lands of West Africa and the southern United States; willy-willies are called cyclones in north-western Australia; and tropical cyclones are called cyclones in the Indian Ocean.

Destruction caused by Cyclones

Cyclones have the power to cause widespread havoc. In the areas affected by the disaster, a large number of people have died. Cyclones end up being the cause of the destruction of homes, buildings, infrastructure, electricity, and livestock. The most impacted species are those that reside in the disaster-affected area. The size, location, and strength of the cyclone all affect how much havoc it causes. Different regions are impacted by cyclones in different ways. By uprooting the trees and altering the canopies, cyclones have an impact on the forest area. Cyclones in coastal areas undermine the banks and embankments. Due to cyclones, the dunes in desert regions change and lose their original shape. Cyclones cause landslides in the mountainous area.

The following three categories describe the hazards that a cyclone poses to an area when it comes.

Primary Hazards

Primary dangers include storms, heavy rain, and strong winds. Low-lying areas close to the coast are drowned as a result of an unnatural rise in sea level, which results in human drownings, the destruction of cattle and their homes, the loss of flora, and the ruin of soil fertility. Houses, trees, communication networks, and other things can all be damaged by strong winds. Primary risks result in significant losses of human life, property, and livestock.

Secondary Hazards

Secondary dangers include freshwater flooding, fire, and floods. Heavy rains produce flooding in the river, which in turn submerges the neighbouring populated areas. The floods also result in the damage of several structures and private property, as well as the erosion of some fertile farming grounds. Strong winds can start forest fires in forested areas, and because of the wind’s strength, these fires can spread quickly and dangerously. This has the potential to seriously harm both the forest and the fauna. Because of these fires, many animals die. Additionally, surrounding areas with human habitats may be impacted.

Tertiary Hazards

Water poisoning, diseases brought on by stagnant water, and an increase in the cost of goods and resources are examples of tertiary hazards. The tertiary dangers have an impact on people. People pass away during these times as a result of a lack of nourishment. Tertiary risks, if not effectively controlled, can be more terrible than primary and secondary hazards.

Measures to save ourselves from adverse effect of cyclones

To save ourselves from the adverse effects of cyclones, it is important to take appropriate measures both before and during the event. Here are some measures that can help:

Early Warning Systems: The first step to saving ourselves from the adverse effects of cyclones is to be informed. Early warning systems can provide timely and accurate information about the storm’s approach, expected intensity, and potential impact. Pay attention to official advisories and take appropriate actions as directed.

Evacuation Planning: If you live in an area that is prone to cyclones, it is important to have a plan in place for evacuating to safer locations. Know the evacuation routes, prepare an emergency kit, and ensure that your family members know what to do in case of an evacuation order.

Secure Your Home: Before the storm arrives, take measures to secure your home, such as reinforcing windows and doors, and clearing your yard of loose objects that could become dangerous projectiles in high winds.

Stock Up on Supplies: Prepare a disaster supply kit with essentials like water, non-perishable food, medicine, and first-aid supplies. It is also advisable to have a backup power source, such as a generator or solar panels.

Stay Indoors: During the cyclone, it is important to stay indoors and away from windows and exterior walls. If you are in a low-lying area, move to higher ground to avoid storm surges and flooding.

After the Cyclone: After the cyclone has passed, take caution when moving around as there may be dangerous debris and downed power lines. Wait for the all-clear signal before venturing outside, and check for any damages to your home before re-entering it.

Overall, taking appropriate measures to prepare for a cyclone and following official advice can help save lives and minimize the damage caused by these powerful storms.

Cyclones have the potential to cause havoc that has profound effects on the economy, society, and environment. Massive recovery and reconstruction operations, including the provision of humanitarian help, the replacement of destroyed infrastructure, and the restoration of natural ecosystems, may be necessary for the impacted areas.
