Although scientists can forecast the weather, it is unlikely to know for sure how many tropical cyclones are there per year due to the increasing effects of climate change. Changes in tropical cyclones are evident as the impact of storm surges and wind speed intensifies each year. That’s why you must make all the necessary preparation for the safety of your family.
In this article, we’re going to share with you where and when do tropical cyclones occur. We’re also going to discuss the impact a tropical cyclone leaves behind to the people.
What is a Tropical Cyclone?
A tropical cyclone that occurs over subtropical and coastal oceans is a hurricane. It is a quick spinning system with high winds, low-pressure core, and a closed low-level atmospheric motion. The same system may be named various terms, including a cyclone, a typhoon or a hurricane, based on its intensity and position.
Tropical cyclones are powerful irregular storms from warm tropical waters. They have an average sustained wind speed reaching 119 kilometers per hour and strong rainfall.
The highest risk to lives and properties, though, comes not from the atmosphere but secondary incidents, including storm waves, flooding, landslides, and tornadoes.
Tropical cyclones are named by different terms, based on where they start in the country.
- Hurricanes occur in the Atlantic Ocean and the eastern north Pacific Ocean.
- Typhoons occur in the western Pacific Ocean.
- Tropical cyclones occur in the South Pacific Ocean and the Indian Ocean.
Where Do Tropical Cyclones Occur
Hurricanes are developing on Earth in about five different basins. The Pacific Ocean is particularly active in particular years with the Philippines suffering more than twenty typhoons and tropical storms.
Hurricanes are not limited to the eastern Pacific and the North Atlantic; they often exist elsewhere in which they are identified as the tropical cyclone (South Atlantic Ocean, Indian Ocean) or typhoons (Western Pacific Ocean). The odds of a South Atlantic hurricane development are minimal.
An Eastern Pacific hurricane will impact Mexico and Hawaii’s western side, while the West Pacific storm strikes South Asia, China, and Japan. The Asian nations in the Indian Subcontinent are also vulnerable to hurricanes from the Indian Ocean, with the Bay of Bengal becoming a cyclonic storm hotspot. A tropical cyclone from the Southwest Indian Ocean will impact Madagascar and all the other nations along the East coast of Africa. At the same time, the one from the Southeast Indian Ocean would strike Australia.
When Does Tropical Cyclone Occur
The Atlantic Basin hurricane season starts on June 1 and finishes on November 30, but several storms may occur outside of those times. Hurricanes form in the Caribbean Sea, the Gulf of Mexico and the Atlantic Ocean throughout the peak season. The most productive time in the Atlantic starts from mid-August to late October. Any of the impacted nations are Bermuda, Eastern Canada, the United States ‘East Coasts, and Central America (Eastern Mexico).
The hurricane season in the Eastern Pacific ends on May 15 and finishes in November. The most productive time is at the beginning of September or the end of August. The East Pacific is the second most significant tropical cyclone region on Earth. In the northeastern Pacific, the hurricanes develop and then travel to the accessible Eastern Pacific. They may also influence western Mexico and southern Baja. The tropical cyclone pushes toward the west side as it evolves and ends up impacting Hawaii.
The hurricane season in the western Pacific begins on July 1 and peaks in early September or early August. It comes to a close in November. It extends from mid-October to mid-May in the South Pacific, hitting its height in early March or late February. The season lasts in the Northern Indian Ocean from the beginning of April until the end of December. It begins in mid-October in the southern sections of the Indian Ocean and finishes in May.
How Many Tropical Cyclones are There Per Year
Roughly 80 tropical cyclones develop across the globe each year.
An average, ten tropical storms form over the Atlantic Ocean, the Caribbean Sea or the Gulf of Mexico from June to November each year. Many of these weather systems linger in the ocean before hitting the coastlines.
Frequency and severity vary according to the cyclone to a cyclone. The total number of tropical storms in the North Atlantic Basin in the long term (1966-2009) is around 11 annually, with only six being hurricanes. More recently (2000-2014), the peak annual total is about 15 tropical storms, including approximately seven hurricanes.
Preparation for the Coming Tropical Cyclone
When you know that the hurricane is headed in your location, you should go ahead and prepare for the coming storm. Here’s a guide ready for storms:
- Make sure to address or get an emergency strategy in hand. The authorities will suggest that you get an action plan worked out in the case time.
- Create a home safety kit, such as:
- Enough water for each person to have a gallon a day
- Three-day supply of non-perishable food
- Battery-powered radio with extra batteries
- First Aid Kit
- Garbage bags
- Phone chargers
- Duct tape
- Wrench or pliers
- Local map
- Manual can opener
- Build a safety-room. Pack one space with fresh water, non-perishable food, flashlights, sheets, tissues, garbage bags, shoes, cleaning caps, food for your pet, and all other needs in your household. It would be far simpler to locate everything you need during the storm.
- The authorities will advise that you “know your place.” Listen to alerts from local news, whether you reside around a dangerous building or region like a river or by the ocean.
- If you are taking drugs, make sure that you remember how to store it in case the electricity goes out. Popular medicines and treatments such as amoxicillin and insulin may be packed in sandwich bags and stored on ice to hold them safe.
Be sure your emergency package is placed in an easy-to-area like a kitchen counter or a coffee table.
Store fresh water, non-perishable food, flashlights, sheets, shoes, cleaning caps, makes all other needs in your house be prepared. With all in one location, it would be far simpler to locate everything you need during the storm or to clean up after the reality.
Impact of Tropical Cyclones
The health consequences of tropical cyclones rely on the number of citizens residing in the immediate path of the hurricane in low-coastal regions, the urban infrastructure and housing construction, and whether there is adequate time to prepare and evacuate.
Tropical cyclones, in several respects, may impact safety directly and indirectly, for example through:
- Increasing flooding and other bodily trauma;
- Increasing flooding and other bodily trauma;
- Worsening the behavioral health consequences associated with emergencies;
- Undermining health networks, hospitals, and programs, leaving people lacking exposure to healthcare when they are desperately needed;
- Destroying critical resources, such as food and water supply;
As tropical cyclones cause flooding and sea waves, the possibility of drowning and diseases spread by water or vectors is increased. Floodwaters can include waste and toxic contaminants, conceal sharp items made of metal or glass and electrical wires, or host harmful snakes or reptiles that may trigger illness, damage, electrocution, and bites.
Climate change affects the force and threat of a tropical cyclone, that’s why it’s essential to be prepared all the time. History reflects that we should not take for granted the damaging effect of a hurricane can bring. Understanding how many tropical cyclones are there per year should give you time to prevent the risk of danger to your family.
