Winds,Storms and Cyclones WINDS,STORMS AND CYCLONES Odisha cyclone The 1999 Odisha cyclone was the most intense recorded tropical cyclone in the North Indian Ocean and among the most destructive in the region. The 1999 Odisha cyclone organized into a tropical depression in the Andaman Sea on 25 October. The disturbance gradually strengthened as it took a west-north-westerly path, reaching cyclonic storm strength the next day. Aided by highly favourable conditions, the storm rapidly intensified, attaining super cyclonic storm intensity on 28 October, before peaking on the next day with winds of 260 km/h (160 mph) and a record-low pressure of 912 mbar The storm maintained this intensity as it made landfall on Odisha on 29 October. The cyclone steadily weakened due to persistent land interaction and dry air, remaining quasi-stationary for two days before slowly drifting offshore as a much weaker system The storm dissipated on 4 November over the Bay of Bengal.

CYCLONE NAMES The tradition started with hurricanes in the Atlantic Ocean, where tropical storms that reach sustained wind speeds of 39 miles per hour were given names. Incidentally, hurricanes, typhoons, cyclones are all the same, just different names for tropical storms in different parts of the world; Hurricane in the Atlantic, Typhoon in the Pacific and Cyclone in the Indian Ocean. Cyclones were usually not named. The tradition started with hurricanes in the Atlantic Ocean, where tropical storms that reach sustained wind speeds of 39 miles per hour were given names. (Incidentally, hurricanes, typhoons, cyclones are all the same, just different names for tropical storms in different parts of the world; Hurricane in the Atlantic, Typhoon in the Pacific and Cyclone in the Indian Ocean). If the storm's wind speed reaches or crosses 74 mph, it is then classified into a hurricane/cyclone/typhoon. Tropical storms are given names and they retain the name if they develop into a cyclone/hurricane/typhoon. When did we start naming Cyclones? Names have been given to Atlantic storms for the past few hundreds of years. Initially, people living in the Caribbean Islands would name the storms after the saint of the day from the Roman Catholic liturgical calendar for the day on which the hurricane/cyclone occurred. The tradition continued till World War II, when forecasters and meteorologists started using female names to identify the storms. In 1953, the US weather service officially adopted the idea and created a new phonetic alphabet (international) of women's names from A to W, leaving out Q, U, X, Y and Z. Subsequent protests by women's liberation bodies in the 60s and 70s helped change the naming procedure for the storms to include male names in 1978. The year's first tropical storm was given the name beginning with the letter "A", the second with the letter "B" and so on through the alphabet. In even-numbered years, odd-numbered storms got men's names and in odd-numbered years, odd-numbered storms got women's names. The naming of tropical cyclones is a recent phenomenon. The process of naming cyclones involves several countries in the region and is done under the aegis of the World Meteorological Organization. For the Indian Ocean region, deliberations for naming cyclones began in 2000 and a formula was agreed upon in 2004. Eight countries in the region - Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand - all contributed a set of names which are assigned sequentially whenever a cyclonic storm develops. The name Nilam was contributed by Pakistan,Murjan - a name that came from Oman. The next in line are Mahasen (from Sri Lanka) and Phailin (from Thailand). The list of names India has added to the database includes Agni, Akash, Bijli, Jal (cyclones which have all occurred since 2004). The Indian names in the queue are Leher, Megh, Sagar and Vayu, while those suggested by Pakistan include Nilofar, Titli and Bulbul. .

Super Cyclone Amphan began forming on May 16 and dissipated on May 21 By NewsGram Desk -May 22, 2020. Cyclone Amphan has caused widespread damage to infrastructure in the coastal states of Odisha and West Bengal. Wikimedia Commons. Sewa International announced the first tranche of $10,000 toward rescue and relief operations as Super Cyclone Amphan devastated vast stretches of two states in India – Odisha and West Bengal. Amphan, which began forming on May 16 and dissipated today, May 21, has caused widespread damage to infrastructure in the coastal states of Odisha and West Bengal as it moved inland with 105 mph winds, heavy sea surge, and massive rain. Boats, agricultural crops, and houses have been destroyed, electricity poles and trees uprooted, and vast stretches of agricultural land, villages, and towns have become inundated. Amphan was, according to NASA estimates, the equivalent of a Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Causing widespread damage over the Eastern parts of India and Bangladesh Amphan is the strongest cyclone to strike the Ganges Delta since 2007 and the first super cyclonic storm to occur in the Bay of Bengal since the 1999 Odisha cyclone. It has claimed 72 lives in India as of today. Adding to the challenges facing rescue and relief efforts is the current pandemic where these affected areas are developing into COVID-19 hotspots. “Sewa International with on the ground partners/volunteers is committed to providing all support to the affected people in this hour of need,” said Swadesh Katoch, VP of Disaster Recovery, Sewa International.

I track the technical conjuring of such on-screen waves – made using everything from scale model wave tanks to computer-generated imagery (CGI) – and explicate how these enable waves’ narrative purposes and effects. I argue that towering waves in film have operated as emblems of (a) the elemental power of cosmic, inhuman, arbitrary forces, (b) the return of the social-environmental repressed, and (c) the power and limits of cinematic media themselves. The most recent fantastical waves, rendered digitally, I suggest, now generate reflexive usages that underwrite either optimistic aesthetics of a nature crafted in partnership with humanity or ironic pessimism about human enterprise in the face of looming ecological disaster. Keywords Anthropocene, animation, disaster, film, waves Résumé Cet article examine les représentations des vagues océaniques dans les films catastrophes et de science-fiction, afin d’appréhender les changements idéologiques inhérents aux relations Homme–océan.

  • Tropical Cyclones
    Tropical Cyclones December 4, 2018 Manifest Pedagogy Geography usually has been considered as a stagnant subject but UPSC has been asking highly dynamic questions linking it with current affairs. The most relevant example being the JUNO Mission question in this year mains. Topics in news are being used as a trigger for static portions in Geography. Cyclones being highly in news needs a focused and holistic understanding by the aspirants to tackle any question on it. Update In news: Super cyclone Amphan has affected West Bengal and Odisha. Static dimensions: What is a Storm surge? 1999 super cyclone of Odisha Current dimensions: IMD classification of cyclones Cyclone Amphan Content: What is a Storm surge? A storm surge is a rise in sea level that occurs during tropical cyclones. It is primarily caused by the relationship between the winds and the ocean’s surface. The water level rises where the winds are strongest. In addition, water is pushed in the direction the winds are blowing. Another factor contributing to storm surge is atmospheric pressure. The pressure is higher at the edges of a cyclone than it is at the centre. This pushes down the water in the outer parts of the storm, causing the water to bulge at the eye and eye wall where the winds have helped add to the rise in sea level. The water level can reach as high as 10 meters if the storm surge happens at the same time as high tide. When a cyclone hits land, the accompanying storm surge will most often flood the surrounding coastal area.

The impacts of Phailin and ensuing floods affected more than 13.2 million people, and caused enormous damage .The estimated total damage to houses, crops and public properties was 14373.47 crore. There was massive destruction of power supply system, communication and transportation system. However, early warning alerts, disseminated four days before landfall of Phailin, allowed for the evacuation and relocation of approximately 1.2 million people, resulting in the largest evacuation operation in India in 23 years. A total of 21 lives were lost as a result of the cyclone and an additional 23 lives due to severe flash flooding in the aftermath of the cyclone. A comparable cyclone, Cyclone 05B, hit Odisha in 1999 with winds of up to 260 km/h, but had a much more than 10,000 lives were lost. Early warning using multiple channels of communication and timely action saved lives during Phailin. Government cooperation, preparedness at the community level, and lessons learned from Cyclone 05B contributed to the successful evacuation operation, effective preparation activities and impact mitigation.

    Super Cyclone Amphan: A Dynamical Case Study Sridhar Balasubramanian∗1 and Vamsi K Chalamalla†2 1Department of Mechanical Engineering and IDP in Climate Studies, Indian Institute of Technology Bombay, Powai, India 2Department of Applied Mechanics, Indian Institute of Technology Delhi, New Delhi, India November 20, 2020 Abstract Cyclone Amphan, a super cyclone in the Bay of Bengal after 21 years, intensified from a cyclonic storm (CAT 1) to a super cyclone (CAT 5) in less than 36 hours. It went on to make landfall over West Bengal as a Very Severe Cyclonic Storm (VSCS) with winds close to 155 kmph. Here, we analyze the dynamics that led to its rapid in- tensification, given that the system struggled to develop initially despite the presence of ripe conditions like high Sea Surface Temperature (SST) in the Bay. Our anal- ysis clearly reveals that a Convectively Coupled Kelvin Wave (CCKW) from upper troposphere might have initiated strong instabilities in the tropopause, which then propagated vertically downward and interacted with surface disturbances to promote convective coupling with the Madden Julian Oscillations (MJO). Such convective cou- pling resulted in a burst of westerly winds along with enhanced vertical mixing and moisture convergence, which eventually led to the formation and intensification of super cyclone, Amphan. 1 Introduction Atmosphere and ocean are replete with inertial waves and intra-seasonal oscillations, which play a very important role in transferring energy and momentum. The Madden Julian Os- cillation (MJO) is the largest intra-seasonal variability, and air-sea interaction is one of the mechanisms contributing to MJO development and its propagation [3,4,6].
