Archives (PRELIMS & MAINS Focus) Hurricane Hilary Syllabus Prelims –Geography Context: Recently, Hurricane Hilary caused extensive damage in the United States. Background:- Hilary is the first tropical storm to hit Southern California in 84 years. About Hurricane Hilary:- IMAGE SOURCE: dailybreeze.com Location: near the west coast of Baja California. Baja California: The long Mexican peninsula bound by the Gulf of California in the east and the North Pacific Ocean in the west. Origin and Trajectory:- It originated as a Tropical Storm off the shores of Mainland Mexico. This weather phenomenon rapidly transformed into a Category 2 hurricane and then into a Category 3 storm Soon, it was officially designated as a Category 4 hurricane, nearly a day before its projected timeline. This rapid intensification is anticipated to continue, leaving open the possibility of a Category 5 upgrade before eventual weakening. ( Cyclones forecast) Categories of Hurricanes:- Hurricanes are categorized on the Saffir-Simpson Hurricane Wind Scale based on their maximum sustained wind speeds. The scale ranges from Category 1 (weakest) to Category 5 (strongest). Each category represents a higher wind speed and potential for damage. Possible Factors behind its intensification:- Scientists expected climate change to not only spike the occurrence of such hurricanes but also make them more intense due to the following implications:- Rise of the surface temperatures of the oceans: global mean sea surface temperature has gone up by close to 0.9 degree Celsius since 1850 and around 0.6 degrees Celsius over the last four decades. Higher sea surface temperatures: it causes marine heat waves, an extreme weather event, which can also make storms like hurricanes and tropical cyclones more intense. Marine heatwaves: they are extended periods of anomalously warm sea surface temperatures in the ocean. El Nino: The situation has been worsened by El Nino, developing for the first time in seven years. This has weakened the vertical wind shear in the eastern Pacific, allowing more hurricanes in the region. El Nino: a weather pattern that refers to an abnormal warming of surface waters in the equatorial Pacific Ocean. Risk or Threat:- Unlike hurricane-prone states on the Gulf of Mexico, California and Mexico’s west coast lack experience in dealing with such events. (Bomb Cyclone) Its expected landfall in the Baja peninsula of Mexico poses risks of landslides, flooding, and extensive damage due to the region’s geographical features and population density. About Hurricane:- Hurricanes are tropical storms that form in the Atlantic Ocean. Wind speeds: at least 119 kilometers (74 miles) per hour. Hurricanes derive their energy from the heat released when moist air rises and condenses into clouds and rain. Key characteristics of hurricanes:- Hurricanes form over warm ocean waters when the sea surface temperature is typically above 26 degrees Celsius (79 degrees Fahrenheit). Low-Pressure Centre: Hurricanes have a well-defined centre of low atmospheric pressure, known as the Strong Winds: winds can reach sustained speeds of at least 74 miles per hour (119 kilometers per hour) or higher. Heavy Rainfall. MUST READ: Hurricane Ida SOURCE: HINDUSTAN TIMES PREVIOUS YEAR QUESTIONS Q.1) Consider the following statements: (2022) High clouds primarily reflect solar radiation and cool the surface of the Earth. Low clouds have a high absorption of infrared radiation emanating from the Earth’s surface and thus cause a warming effect. Which of the statements given above is/are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Q.2) Consider the following statements: (2018) The Barren Island volcano is an active volcano located in the Indian territory. Barren Island lies about 140 km east of Great Nicobar. The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then. Which of the statements given above is/are correct? 1 only 2 and 3 3 only 1 and 3 Bharat New Car Assessment Programme (Bharat NCAP) Syllabus Prelims –Governance Context: Union Minister of Road Transport and Highways Shri Nitin Gadkari launched the Bharat New Car Assessment Programme (Bharat NCAP) recently. About Bharat New Car Assessment Programme (Bharat NCAP):- Launched:2023. Implementation: October 1, 2023. Ministry: Ministry of Road Transport and Highways. Objectives: to enhance road safety by elevating vehicle safety standards for up to 3.5-tonne vehicles in India. It is a safety assessment program for passenger vehicles weighing less than 3.5 tonnes and capable of seating up to eight people. Salient Features of Bharat NCAP:- It proposes a mechanism of awarding ‘Star Ratings’ to automobiles based on their performance in crash tests. The voluntary Bharat NCAP would assign vehicles between one and five stars on parameters such as Adult Occupant Protection (AOP), Child Occupant Protection (COP), and Safety Assist Technologies (SAT). This will help assess to what extent a car may suffer damage in the event of an Potential car buyers can refer to these star ratings to decide which car to buy by comparing the safety standards. Bharat NCAP standard is aligned with global benchmarks and it is beyond minimum regulatory requirements. The testing of vehicles for this programme will be carried out at testing agencies, with the necessary infrastructure. Benefits of NCAP: Develop a safety-sensitive car market in India. Consumer Awareness. Enhanced Safety and Export Potential. Making the Indian automobile industry self-reliant. (Atmanirbhar Bharat 3.0) MUST READ: Electric Vehicles SOURCE: PIB PREVIOUS YEAR QUESTIONS Q.1) Consider the following actions: (2023) Detection of car crash/ collision which results in the deployment of airbags almost instantaneously. Detection of accidental free fall of a laptop towards the ground which results in the immediate turning off of the hard drive.
