Oct. 2019 DNS Notes - Revision Title 1. India, Saudi to form strategic council (The Hindu Page 13) Syllabus Mains: GS Paper II – International Relations Theme India-Saudi bilateral relations Highlights Context Prime Minister Narendra Modi visit to Riyadh • For the second time, Indian Prime Minister Narendra Modi is travelling to Saudi Arabia to attend the Future Investment Summit to be held in Riyadh on October 29-31. • This bonhomie has come about at a time when mega economic reform programs are underway in Saudi Arabia, for which it welcomes India’s economic as well as technological assistance. • Likewise, New Delhi looks for Saudi investments in India’s petrochemicals, infrastructure, and mining sectors alongside cooperation in economic and security matters. Outcomes Expected- • India and Saudi Arabia are set to sign an agreement for creating a bilateral strategic partnership council. Formation of the Council has been under discussion for some time. • Establishment of Strategic Partnership Council will further elevate the relations between the two countries. • The council will include multiple sections involving the External Affairs Ministry and NITI Aayog and counterpart organisations from Saudi Arabia. • The council will be led by Mr. Modi and King Salman bin Abdulaziz Al Saud. • It is expected, during Modi’s visit, that both sides will sign energy deals, including the promise of Saudi participation in India’s strategic petroleum reserve. What it means for India at present times? • Mr. Modi’s visit is significant as it comes three months after India ended the special status of Kashmir and feels that Kashmir is unlikely to get any attention from the Saudi rulers( given deteriorating Saudi-Pak relation in recent times) • Strategic considerations like India’s energy security and our desire to ensure stability in the Gulf region. What it means for S.Arabia at present times? • Visit is expected to boost the Crown Prince’s global stature which suffered after Saudi journalist Jamal Khashoggi was brutally killed in the Saudi consulate in Istanbul. • The visit is a vote of confidence in the leadership of Crown Prince bin Salman. Tracing Relations? • Historically - Up untill Cold War period India-Saudi Arabia ties were mainly determined by the Pakistani factor. For decades, this prevented both New Delhi and Riyadh from discovering the strategic importance of engaging one another. But, over a period, they have begun to disentangle themselves from certain inhibitions of the past. • Recent times – we are witnessing growing closeness between New Delhi and Riyadh. • Strategic importance been accorded by both countries to one another. • Today’s Indo-Saudi cooperation is no longer restricted to the traditional sphere of oil- energy trade. Instead, the relationship has become multifaceted. • During National Security Advisor Ajit Doval’s visit to Riyadh early October this year- S. Arabia reportedly conveyed that it understood India’s “approach” and “actions” Dated: 29. Oct. 2019 DNS Notes - Revision regarding the abrogation of Article 370 in Jammu and Kashmir. Thereby took neutral stance on Kashmir. • During the visit of Crown Prince Mohammed bin Salman to India in February agreement reached to constitute a “Comprehensive Security Dialogue” at the national security adviser (NSA) level and set up a Joint Working Group on Counter-Terrorism was timely. • Navies of both countries will hold their first joint naval exercises either toward the end of 2019. Personal Notes Dated: 29. Oct. 2019 DNS Notes - Revision Dated: 29. Oct. 2019 DNS Notes - Revision Title 2. The many gaps in NCRB data (The Hindu Page 11) Syllabus Mains: GS Paper II – Polity and Governance Theme Data on crimes in India Highlights Context National Crime Records Bureau (NCRB) has recently published statistics on “Crime in India – 2017” and has categorised offences into various categories. NCRB has also published “Prison Statistics India – 2017” covering various aspects of prison administration. In the backdrop of these two reports, this article mentions certain gaps in data collection and categorisation. So, let us go through different concerns highlighted in the article: Concerns 1. Some offences under crime has been categorised outside the provisions of Indian Penal Code and other special and local laws. 2. There is inadequate explanation for classification of offence. For instance, while reporting the offence of murder, NCRB has segregated the numbers based on the different motives for murder like honour killing and dowry but has not explained the reason for such categorisation. 3. In contrast to crime statistics, prison statistics do not provide any such offence-wise data on undertrials and convicts. This prevents cross-referencing and examination of the numbers in both reports. 4. Prison statistics provide information on different kinds of sentences being served by convicts but these numbers have not been categorised on the basis of offences. Thus, it is impossible to - analyse any pattern for sentencing for various offences and in various States or formulate policy on such sentencing. 5. There are concerns on the methods of computation and presentation of data. For instance, the crime statistics report, while recording rates of recidivism (the tendency of a convicted criminal to reoffend), collects State-wise information on the number of juveniles and adults who were arrested earlier but not convicted, and those who were previously convicted. This becomes a concern as socio-economically marginalised people repeatedly come in conflict with the law and are routinely arrested and released on mere suspicion. Even for those who were arrested and convicted previously, the data do not speak of the nature of crimes involving their prior conviction and the crimes leading to their present arrest. 6. There are methodological concerns about the rate of calculating charge-sheeting, which has been measured based on the total number of cases disposed of by the police, and not the total number of cases for investigation. By leaving the cases of ongoing investigation, the reports leave a large number of cases in the final data. 7. There are similar concerns about the presentation of data on arrests, convictions and acquittals. It is unclear if the number of persons acquitted, discharged and convicted is calculated in reference to the number of persons arrested in 2017, or those charged and arrested in previous years. 8. Further, the statistics on arrests, convictions and acquittals do not relate to the total number of cases disposed of by courts in 2017. Dated: 29. Oct. 2019 DNS Notes - Revision Way Forward In absence of reliable data on crimes and prisons, it is difficult to formulate robust policies on criminal justice system including prison reforms. The article mentions that such robust policies are necessary for reforming prisoners as 94.4% of those entering the criminal justice system were arrested for the first time. So, in order to explore more precise and effective solutions to criminal justice issues, NCRB must first take steps towards ensuring the accuracy, reliability and comprehensiveness of these reports.

Supercyclone ‘Kyarr’ moves away from Indian coast (The Hindu Page 09) Syllabus Mains: GS Paper I – Geography Prelims: Physical Geography Theme Tropical Cyclones Highlights Context According to IMD, the Supercyclone ‘Kyarr’ in the Arabian Sea has moved westwards and away from India’s coast. Classification of cyclones • Cyclones are classified on the basis of the wind speed • Depression • The lowest classification with sustained wind speeds of between 31–49 km/h. • Deep Depression: Intensification of depression to about 50-61 km/h results in Deep Depression. • Category 1: Cyclonic storm • A Deep Depression that develops wind speeds of 62–88 km/h is called a Cyclonic storm. • Category 2: Severe Cyclonic Storm: 89–117 km/h • Category 3: Very Severe Cyclonic Storm: 118–166 km/h • Category 4: Extremely Severe Cyclonic Storm: 166–221 km/h • Category 5: Super Cyclonic Storm: The highest classification used in the North Indian Ocean with wind speeds above 222 km/h. About Kyarr • Kyarr is the 1st super cyclone developed over northern Indian Ocean since Cyclone Gonu in 2007. • Further it is the 7th storm this season over northern Indian Ocean. • This is 1st year since 1998 more than 6 storms have developed in a season. • The main reason for development of so many storms in a year over Indian Ocean is the record level of positive Indian Ocean dipole this year. Positive Indian Ocean Dipole and Kyarr • During the positive phase of Indian Ocean dipole the water over western Indian Ocean is warmer than normal particularly in the Arabian Sea. As a result cooler waters from Australia moves westward towards Arabian Sea it intensifies the depressions in the Arabian sea aggregating into a tropical cyclone. • 2019 witnessed the record level of positive phase of Indian Ocean Dipole resulting in development of multiple storms and resultant intensification into a super cyclone. Dated: 29. Oct. 2019 DNS Notes - Revision About Kyarr Path of Super cyclone Kyarr • Weak area of low pressure began to materialize over the southeast Arabian Sea resulting in formation of depression. • By 2 Oct it organized into a tropical storm eventually intensifying into a Category-3 cyclonic storm by Oct. 25 and 26. • Moving further north-westwards into the ocean, it has gathered more wind speeds upto 250 km/h forming what is called a super cyclone. • As it moves further north-westwards (closer to land), it is likely to weaken to about 130 kmph by November 1.

  • Super Cyclone Amphan
    Super Cyclone Amphan •Cyclone Amphan is a tropical cyclone formed over the Bay of Bengal that has intensified and likely to turn into a “super cyclonic storm (maximum wind speed is 224 kmph)”. •It has been named by Thailand. •Amphan is the equivalent of a Category 5 hurricane on the Saffir- Simpson Hurricane Wind Scale. •By the time it makes landfall in West Bengal, Amphan is expected to tone down into a category 4 Extremely Severe Cyclonic (ESC) storm with a wind speed of 165-175 kmph and gusting to 195 kmph. What makes it a nightmare? •This is the first super cyclone to form in the Bay of Bengal after the 1999 super cyclone that hit Odisha and claimed more than 10,000 lives. •It is the third super cyclone to occur in the North Indian Ocean region after 1999 which comprises of the Bay of Bengal, the Arabian Sea and the northern part of the Indian Ocean. •The other two super cyclones were Cyclone Kyarr in 2019 and Cyclone Gonu in 2007 Recent cyclones in the region •From 1965 to 2017, the Bay of Bengal and the Arabian Sea collectively registered 46 ‘severe cyclonic storms’. •More than half of them occurred between October and December. •Seven of them occurred in May and only two (in 1966 and 1976) were recorded in April, according to data from the IMDs cyclone statistics unit. •Cyclone Phailin in 2013 and the super cyclone of 1999 — both of which hit coastal Odisha — have been the most powerful cyclones in the Bay of Bengal in the past two decades in terms of wind speed.

  • Weather in India
    MAUSAM, 71, 4 (October 2020), 757-778 Weather in India POST MONSOON SEASON (October - December 2019)† 1. Introduction Post monsoon season 2019 was cyclogenetically an active season in the Arabian Sea which witnessed the formation of 5 intense low-pressure systems of the total 6 in the North Indian Ocean (NIO) comprising of the Bay of Bengal and the Arabian Sea. The 5 systems formed in the Arabian Sea, included two Deep Depressions, one Cyclonic Storm, one Extremely Severe Cyclonic Storm and one Super Cyclonic storm. The year as a whole also witnessed development of more intense cyclones over the Arabian Sea corresponding with strongly positive Indian Ocean Dipole. However, the cyclone activity over the Bay of Bengal during 2019 had been slightly subdued, as only 3 cyclones formed against the normal of 4 per year. In a first since 1965, two cyclones occurred, simultaneously in the Arabian Sea, with the formation of Cyclone ‘MAHA’ (30th October - 7th November), even as Super Cyclonic Storm ‘Kyarr’ (24th October - 2nd November) prevailed over the region. Likewise, Extremely Severe Cyclonic Storm ‘MAHA’ co-existed with Very Severe Cyclonic Storm (VSCS) ‘BULBUL’ over the Bay of Bengal during 5-7 November. Similarly, co-existence of Fig. 1.

  • Cyclonic Storm ‘NISARGA’
    Daily Current Capsules – 03rd June 2020 Geophysical phenomena Cyclonic Storm ‘NISARGA’ Relevance IN – Prelims ( about Cyclone Nisarga + about the naming of cyclone + colour coded weather warning +Mains GS I (Important Geophysical phenomena ) What’s the NEWS A low pressure is currently over east-central Arabian Sea and the Lakshadweep Islands. It is likely to intensify into a depression in the next 12 hours and a cyclonic circulation in the next 24 hours A low pressure area is the first stage of any cyclone. It is likely to cross north Maharashtra and south Gujarat coasts between Harihareshwar town in Maharashtra''s Raigad district and Daman as a severe cyclonic storm Know! about Nisarga (named by Bangladesh) India is now bracing to face another cyclone (last week Cyclone Amphan caused widespread destruction in West Bengal and parts of Odisha) which is headed towards the coastline of Maharashtra and Gujarat. ''Nisarga'', which is currently brewing in the Arabian Sea, means nature and was termed by India''s neighbouring country -- Bangladesh. The name was accorded in a list formulated by a group of countries. Bangladesh had also suggested ''Fani'', which had made a landfall in Odisha on May 3, 2019. The extremely severe cyclone had caused extensive damage. Know! about the naming of Cyclone The naming of cyclones in the Indian Ocean began in 2000 and a formula was agreed in 2004. The next few cyclones will be named Gati (named by India), Nivar (Iran), Burevi (Maldives), Tauktae (Myanmar) and Yaas (Oman). Tropical cyclones are named to help the scientific community and disaster managers to identify cyclones, create awareness and effectively disseminate warnings to wider audiences.
