Cyclones – Why and How are they named?

Have you ever wondered how do scientists decides the name for cyclones? Read the whole article to learn it.

Weather forecasters give each tropical cyclone a name to avoid confusion. Each year, tropical cyclones receive names in alphabetical order. Women and men’s names are alternated. The name list is proposed by the National Meteorological and Hydrological Services (NMHSs) of WMO Members of a specific region, and approved by the respective tropical cyclone regional bodies at their annual/bi-annual sessions.

HISTORICAL BACKGROUND

The practice of naming storms (tropical cyclones) began years ago in order to help in the quick identification of storms in warning messages because names are presumed to be far easier to remember than numbers and technical terms. In the beginning, storms were named arbitrarily. An Atlantic storm that ripped off the mast of a boat named Antje became known as Antje’s hurricane. Then the mid-1900’s saw the start of the practice of using feminine names for storms.

In the pursuit of a more organized and efficient naming system, meteorologists later decided to identify storms using names from a list arranged alphabetically. Thus, a storm with a name which begins with A, like Anne, would be the first storm to occur in the year. By the end of the 1900’s, forecasters started using male names for those forming in the Southern Hemisphere.

Since 1953, Atlantic tropical storms have been named from lists originated by the National Hurricane Centre. The original name lists featured only women’s names. In 1979, men’s names were introduced and they alternate with the women’s names.

Six lists are used in rotation. Thus, the 2019 list will be used again in 2025. The names of tropical cyclones over the north Indian Ocean is however not repeated. Once used, it will cease to be used again.

Why are cyclones given a name ?

Naming of Tropical Cyclones (TCs) helps the scientific community, disaster managers, media and general masses to

  • identify each individual cyclone.
  • use of short, distinctive given names in written as well as spoken communications is quicker and less subject to error than the older more cumbersome latitude-longitude identification methods.
  • create awareness of its development.
  • remove confusion in case of simultaneous occurrence of TCs over a region
  • rapidly and effectively disseminate warnings to much wider audience

These advantages are especially important in exchanging detailed storm information between hundreds of widely scattered stations, coastal bases, and ships at sea.

Criteria for name selection

  • The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender
  • Name should be chosen in such a way that it does not hurt the sentiments of any group of population over the globe
  • It should not be very rude and cruel in nature
  • It should be short, easy to pronounce and should not be offensive to any member
  • The maximum length of the name will be eight letters
  • The proposed name should be provided along with its pronunciation and voice over

Protocol to Select a name for a cyclone

For north Indian Ocean including Bay of Bengal and Arabian Sea, the RSMC, New Delhi assigns the name to tropical cyclones following a standard procedure.

The naming of the tropical cyclones over the north Indian Ocean commenced from September 2004. This list contained names proposed by then eight member countries of WMO/ESCAP PTC, viz., Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand. A new list containing 169 names has been made available in 2020.

ROLE OF QUAD IN SOUTH CHINA SEA

BY DAKSHITA NAITHANI

The Quadrilateral Dialogue was established in 2007 when four countries—the United States, India, Japan, and Australia—joined forces. However, it did not take off at first due to a variety of factors, and it was resurrected in 2017 after almost a decade due to factors such as growing country convergence, the expanding importance of the Indo-Pacific area, and rising threat sentiments toward China, amongst many others.

The origins of QUAD may be traced back to the Malabar Exercise. Malabar began as a modest Passage Exercise named PASSEX between the Indian and US Navies in 1992, but was halted after India’s nuclear testing in Pokhran in 1998. It was later restarted in 2002. Since its inception in 2002, QUAD has become an annual event. With the addition of Japan in 2015, it has become a trilateral practice.

The Quad’s goal remains intact: to promote the economic and security objectives of those nations with genuine and essential interests, to devise a new approach for keeping the Indo-key Pacific’s maritime lanes free of foreign influence. It has become necessary in view of the increased need for information exchange in the maritime sector. With the growing presence of the Chinese Navy in the Indian Ocean, awareness is a key subject for the Navy. After 2008, China increased its presence in the Region under the pretext of anti-piracy operations, even deploying submarines for the objective. In 2017, China formally established its first overseas facility near Djibouti, in the Horn of Africa.

What are the underlying challenges?

The environment in which QUAD has been resurrected, as well as subsequent engagements like as Malabar Exercise 2020, are regarded as governed by a counter-China narrative. There are several features that may not constitute sites of convergence, despite how they appear.

China’s influence: China has significant economic links with Quad partners, particularly Australia, which is what it may use to compel or sway nations to its side. This might prove to be an issue for India.

Maritime orientation: Quad is a marine rather than a land-based organisation because of its strong concentration on the Indo-Pacific. This raises some important concerns about the basis of collaboration with Asia-Pacific and Eurasian countries.

Differing perspectives. There are conflicting viewpoints on certain situations, such as the Myanmar crisis as seen through the eyes of the United States and India. India has remained silent in the face of Japan’s expressed worry that China is attempting to alter the status quo in the East and South China Seas.

Advantages in Space- When QUAD representatives join forces in space, they have significant benefits and are able to fight China. This includes (a) lowering the extremely high expenses of building a dock in order to promote the development of interplanetary vehicles (IPVs). (b) One member state has benefits that will compliment each other and will lead to a successful Mars exploration and the construction of support facilities that will be necessary for effective asteroid belt mining. (c) All member countries bring a high degree of convergence in space applications, for example, the United States has the advanced technological base required for advanced avionics, which will form the backbone for both the construction of a space dock and the construction of IPVs; India has a highly educated and inexpensive working population, which will lower the cost of space; and Australia has the natural resources required for exploration.

The Quad met in Tokyo on October 6, 2020, for the second time since the organisation revived in November 2017. It was the second such gathering, following the inaugural virtual meeting in June, and the first high-level Quad meeting since the 2019 foreign ministers’ meeting in New York on the margins of the UN General Assembly meeting. Furthermore, given mounting worries about Beijing’s hostile conduct and growing suspicions about China’s management of the COVID-19 outbreak in Wuhan, the meeting’s timing and circumstances added to its relevance.

China’s ‘incremental encroachment strategy’ in the South China Sea (SCS) is a source of worry not only for the countries currently affected by the loss of influence over the Exclusive Economic Zone (EEZ), but also for the rest of the world, as China may be able to exercise a monopoly over SCS Sea Lines of Communication (SLOC). Affected nations lack the necessary power to stand up to China, and so will be forced to accept a one-sided agreement such as the China-driven “Code of Conduct” (COC).

As a result, Chinese adventurism must be restrained by other major maritime countries in the global interest. The fact that China could establish a military facility in the SCS despite the existence of the US Navy shows that worldwide criticism and more effort are required to prevent the SCS from becoming “China’s lake.”

Quad may not have the fangs it needs right now, but there is no other option than to establish a prospective structure like this involving likeminded maritime countries with shared strategic objectives in the Indo-Pacific. Various perspectives on the Quad’s role, viability, and prospects have been expressed on several occasions. Because Quad is a security conversation platform rather than a military alliance, aspirations from it must be suitably limited for the time being. 

In the Indo-Pacific, each Quad member sees a distinct threat. While three of the Quad’s warships (Australia, the United States, and Japan) operate under the NATO military alliance structure, India is not a member of any military alliance, while being a reliable ally of two of them. Without India, the trilateral conversation between the three NATO partners has been since 2002. Because India is the only Quad member with an unresolved land boundary with China, it will take a different strategy to dealing with China.

The Quad has emphasised the importance of ASEAN in the Indo-Pacific; nevertheless, their membership in it is a contentious topic owing to Chinese influence. In reaction to China’s claim to the nine-dash line in the SCS, there are divisions within the ASEAN grouping. Some of the ASEAN nations that have been harmed had previously raised a faint voice opposing Chinese aggressiveness, expecting international powers to rein in China’s antics.

Quad’s shared goal of putting its vision of a free and open Indo-Pacific on a “rules-based” legal framework to ensure freedom of passage in the global SLOC requires some reflection and strengthening. The United Nations Convention on the Law of the Sea (UNCLOS III) has been ratified by Australia, India, and Japan, but the United States has yet to do so. This ratification will be required in order to maintain a high moral ground when implementing the agreement.

China is relatively certain that the US and any other country would not employ military action against it, given the current world geopolitical situation. Beijing is also beefing up its naval capabilities. Quad aims to upgrade beyond its Malabar workouts in this situation.

In the Indo-Pacific, Quad members must maintain freedom of navigation exercises and military posture as China continues to do so. Chinese expansion must continue to be condemned by the international community. Quad may not be powerful enough to stop Chinese adventurism in its current form, but it has the potential to become one of the most effective instruments if the afflicted nations and the international community band together to address their mutual concerns.

The navies of Australia, India, Japan, and the United States conducted their largest naval drills this month, sending warships, submarines, and aircraft to the Indian Ocean, signalling the four countries’ seriousness in countering China’s military and political influence in the Indo-Pacific region, according to analysts. Officials in Beijing were silent, but Chinese state media denounced the Malabar naval manoeuvres, calling them a threat to regional stability, according to the Global Times newspaper.

Conclusion

The Quad is developing as one of the major multilateral which is committed to increased security collaboration in the post–COVID-19 international order, given the rising pace and scope of the group’s work. Furthermore, having an active Quad dispels the long-held belief that the Indo-Pacific is mainly inert. With the stakes higher than ever, each of the Quad’s four members must play a larger role in balancing the Indo-threats Pacific’s and power moves. Every step made by the Quad will make it more difficult for Beijing to realise its great-power goals. As a result, China will be unnerved by the Quad’s emergence as a united front championing a free and open Indo-Pacific. Furthermore, if China continues to push the security boundaries and put the Quad members to the test, the organisation will morph into the anti-China squad Beijing fears.

Knowing the Indian Ocean

After the Pacific and the Atlantic, let’s move onto the Indian ocean

Hope you remember the acronym- PAISA

  1. Pacific
  2. Atlantic
  3. Indian
  4. Southern
  5. Antarctic

These oceans are arranged in the decreasing order of their sizes.

The third largest ocean based upon its size, it is the only ocean in the whole world to be named after a country. It covers 27,240,000 sq ml or 19.8 percent of the world’s water on the Earth’s surface. Bounded by Asia to the north, southern ocean to the south, Africa to the west and the Indonesian islands (the strait of Malacca) and Australia to the east, it also hass many marginal seas and islands.

Marginal Seas:

  1. Bay of Bengal
  2. Arabian sea
  3. Laccadive sea
  4. Java sea
  5. Andaman Sea
  6. Timor Sea
  7. Red sea
  8. Persian Gulf
  9. Gulf of Aden
  10. Gulf of Oman
  11. Gulf of Suez
  12. Molucca sea
  13. Gulf of Khambhat

Major islands

  1. Andaman and Nicobar
  2. Lakshadweep
  3. Maldives
  4. Madagascar
  5. Reunion
  6. Seychelles
  7. Mauritius
  8. Comoros
  9. Indonesia

Enclosed by land on three sides, it is centered along the Indian peninsula and doesn’t extend from pole to pole. It has roughly 800 drainage basin of which 50% are located in Asia, 30 % in Africa and 20% in Australia. It is considered to have subtropical climate. The northern half of the Indian ocean experience monsoon winds that lead to reversal in direction of winds (caused by the movement of ITCZ that in summers reaches above the Tibetan plateau, due to the apparent movement of sun) during summers and winters. This brings the monsoon winds to India during the rainy season(80% of the Monsoon rains dependent on them).

40 % of the total sediments found in this ocean are the results of deposition of the Ganga and Indus fans, the largest submarine fans of the world. The western Indian ocean has the largest phytoplankton blooms in summer due to the monsoon winds (they lead to the ocean water upwelling, building nutrient rich cold water to the surface of the ocean). These phytoplankton later support a complete ecosystem, acting as the primary food producers in the chain, in the ocean leading to high concentration of fish and other marine organisms. Thus, harm to the growth of these phytoplankton (continuously on the rise due to global warming, dumping of acidic and industrial waste water and algae bloom) can further destroy the fragile marine ecosystem.

There are 10 large marine ecosystems in the Indian Ocean-

  1. Agulhas current
  2. Somali coastal current
  3. Red sea current
  4. Persian gulf current
  5. Arabian sea
  6. Bay of Bengal
  7. Gulf of Thailand
  8. West central Australian shelf
  9. Northwest Australian shelf
  10. Southwest Australian shelf

Coastal reefs, sea grass bed and Mangrove forest: The most productive and important ecosystems. This ocean has 36 biodiversity hotspots and is an actively spreading and expanding ocean(having only two trenches- The Java and Sunda trench and the Makaran trench). It also has an active volcanic hotspot- The Reunion hotspot(currently below the reunion islands). Salinity follows the trends similar to the Atlantic ocean(though it doesn’t extend towards the poles.)

This is all about the Indian ocean. See you tomorrow with the Southern ocean.
