Excessive rainfall can also lead to floods and landslides, causing damage to crops and infrastructure |
El Nino and Indian Monsoon
- El Nino and its impact on Indian monsoon: El Nino refers to abnormal warming of surface waters in the equatorial Pacific Ocean, which tends to suppress monsoon rainfall in India.
- Phases of El Nino Southern Oscillation (ENSO): ENSO consists of three phases in the Pacific Ocean: El Nino, La Nina (abnormal cooling), and a neutral phase with sea surface temperatures close to long-term averages.
- Ocean and atmospheric conditions: ENSO involves not only temperature abnormalities of sea surface waters but also atmospheric conditions, including differences in sea-level air pressure and wind strength and direction.
- Southern oscillation and the role of winds: Southern Oscillation Index measures the difference in sea-level air pressure over the western and eastern sides of the Pacific Ocean, while wind patterns play a crucial role in ENSO.
Factors triggering El Nino
- Weakening trade winds: When the trade winds in the tropical Pacific weaken, it contributes to the occurrence of El Nino by reducing the movement of warm surface waters.
- Changes in ocean currents: Alterations in the normal patterns of ocean currents can trigger El Nino events as they affect the distribution and accumulation of warm water in the central and eastern Pacific.
- Variations in atmospheric pressure: Fluctuations in atmospheric pressure patterns disrupt the typical circulation associated with trade winds, which can initiate the onset of El Nino conditions.
- Influence of oceanic Kelvin waves: The presence and behavior of oceanic Kelvin waves, large-scale waves that transport warm water eastward, play a role in the development and intensification of El Nino events.
- Interactions with other climate modes: El Nino can be influenced by the interactions and connections with other climate phenomena such as the Indian Ocean Dipole and the Madden-Julian Oscillation, which can impact the oceanic and atmospheric conditions in the Pacific region.
Measuring the Cycle
(1) Oceanic Nino Index (ONI)
- Measures the oceanic component of El Nino Southern Oscillation (ENSO).
- Tracks the departure from average sea surface temperatures in the tropical Pacific Ocean.
- Helps quantify the intensity and duration of El Nino or La Nina events.
- Typically based on a rolling three-month average of sea surface temperature anomalies in specific regions.
(2) Southern Oscillation Index (SOI)
- Measures the atmospheric component of ENSO.
- Quantifies the difference in air pressure between two locations: Tahiti and Darwin.
- Positive SOI values indicate higher pressure in the eastern Pacific and lower pressure in the western Pacific.
- Negative SOI values indicate lower pressure in the eastern Pacific and higher pressure in the western Pacific.
- Reflects the strength and changes in the atmospheric circulation patterns associated with ENSO.
- Used to assess the phase and strength of ENSO and its impact on global weather and climate patterns.
Economic impact of El Nino on Indian Agriculture
- Drought and reduced rainfall: El Nino events often lead to below-average monsoon rainfall in India, resulting in drought conditions in various regions.
- Crop failure and lower yields: Lack of adequate water availability can lead to crop failure or lower yields for major crops such as rice, wheat, pulses, and oilseeds.
- Increased input costs: During El Nino-induced droughts, farmers may need to invest in additional irrigation, water management, and supplementary feeding for livestock, leading to increased input costs.
- Price fluctuations: Reduced crop production due to El Nino can affect market supply, leading to price fluctuations and potential inflation in food prices.
- Livestock and fisheries: Water scarcity and changes in marine ecosystems can negatively affect animal husbandry and fishing activities, disrupting the livelihoods of those dependent on these sectors.
- Rural livelihoods and migration: The economic stress created can impact rural livelihoods, leading to increased migration from rural to urban areas in search of alternative employment opportunities.

From UPSC perspective, the following things are important :
Prelims level: Betelgeuse
Mains level: NA
Central Idea: Recent research has shed light on the Betelgeuse’s current stage and its potential fate as it approaches the end of its lifecycle.
Betelgeuse: The Bright Red Star in Orion
- Easily visible in the constellation Orion, Betelgeuse is a bright red star known as “Thiruvathirai” or “Ardra” in Indian astronomy.
- It is a massive star that undergoes the carbon-burning stage, leading to its eventual collapse into a supernova.
How is it dying?
- Massive stars like Betelgeuse exhaust their hydrogen fuel and transition to using helium to create carbon.
- The energy released during helium fusion is lower than that of hydrogen, requiring the star to burn more helium to maintain stability.
- Eventually, the helium is depleted, leading to the star’s progression through various burning stages, including carbon and silicon burning.
Pulsation and Betelgeuse’s Death Throes
- Researchers studying Betelgeuse have observed its pulsation, indicating its stage of evolution.
- The observed pulsation aligns with theoretical estimates of the late carbon-burning stage, suggesting that Betelgeuse is in its death throes.
- Astronomers detect the expansion and contraction of Betelgeuse by analyzing its pulsation and corresponding brightness variations.
- Previous studies disagreed on which pulsation period is fundamental, with one team considering 417 days and another team proposing 2,190 days.
- Researchers conclude that it is in the final stage of burning carbon, considering the 2,190-day pulse as fundamental.

From UPSC perspective, the following things are important :
Prelims level: Green Hydrogen
Mains level: Read the attached story
Central Idea
- Researchers from IIT-Madras have developed components for a cost-effective method of electrolyzing seawater to produce green hydrogen.
- The current alkaline water electrolyzer technology is energy-intensive, requires an expensive oxide-polymer separator, and uses fresh water.
Generating Green Hydrogen
- Instead of using fresh water, the researchers developed an electrolyzer that utilizes alkaline seawater.
- Carbon-based support material was used for the electrodes to minimize corrosion.
- Transition metal-based catalysts were designed to catalyze both oxygen and hydrogen evolution reactions, improving the production of hydrogen and oxygen.
- A cellulose-based separator was developed to allow hydroxide ions to pass through while preventing crossover of oxygen and hydrogen.
How does Electrolysis take place?
- The alkaline water electrolyzer involves two half-reactions at the anode and cathode.
- At the cathode, water dissociates into H+ and hydroxide ions, with H+ ions converting into hydrogen.
- Hydroxide ions produced at the cathode pass through the separator, and oxygen is generated at the anode.
- When seawater is used, hypochlorite formation occurs at the anode, causing corrosion and reducing oxygen production. Impurities also affect the hydrogen evolution reaction at the cathode.
How were the Catalyst and Electrode designed?
- The carbon-based support material was used for both anode and cathode electrodes to prevent corrosion.
- The catalyst coating on the support material enhances hydrogen production at the cathode and oxygen production at the anode.
- Transition bimetals in the catalyst are selective toward oxygen evolution reaction, overcoming the challenge of hypochlorite formation.
- Despite impurities adsorbed on the cathode, the catalyst promotes hydrogen evolution, increasing hydrogen production.
What made this device novel?
- The team developed a cellulose-based separator to separate the anode and cathode.
- The separator allows hydroxide ions to pass through but minimizes the crossover of hydrogen and oxygen.
- The separator shows high resistance to degradation in seawater.
Experimental Results and Performance
- The assembled electrolyzer achieved a seawater splitting voltage of 1.73 V at 10 mA/sq.cm and 26 degrees C.
- The optimized parameters enable the electrolyzer to directly use photovoltaic-derived voltage for green hydrogen production.
- Two prototypes of different dimensions were developed, producing hydrogen at rates of 250 ml/hour and 1 liter/hour.
- A stack of three cells produced hydrogen at a rate of about 4 liters/hour.

- Studying how different particles interact with Higgs bosons and understanding the properties of Higgs bosons helps reveal information about the universe.
- The recent detection of Higgs boson decay to a Z boson and a photon provides noteworthy insights.
Role of Virtual Particles
- Quantum field theory suggests that space at the subatomic level is filled with virtual particles that constantly appear and disappear.
- Higgs bosons interact fleetingly with virtual particles during their creation, resulting in the production of a Z boson and a photon.
New Result and Probability
- The Standard Model predicts that the Higgs boson will decay into a Z boson and a photon 0.1% of the time.
- The LHC needed to produce a significant number of Higgs bosons to observe this decay pathway.
Confirmation and Statistical Precision
- The ATLAS and CMS detectors, which previously observed the decay independently, combined their data for increased statistical precision.
- Although the significance is not yet 100%, the combined data enhanced the confirmation of the Higgs boson decay.
Significance for the Standard Model
- Physicists seek to detect and validate the predicted decay pathways of the Higgs boson according to the Standard Model.
- Precise testing of the model’s predictions helps identify potential deviations and explore new theories in physics.
Implications for New Theories
- Higher decay rates through the observed pathway could support new theories beyond the Standard Model.
- Experimental evidence from the LHC could contribute to advancements in scientific understanding.
Back2Basics: Standard Model
- The Standard Model is a theoretical framework in physics that describes the fundamental particles and their interactions, except for gravity.
- It provides a comprehensive understanding of three of the four fundamental forces: electromagnetic, strong nuclear, and weak nuclear forces.
- Developed in the mid-20th century, the Standard Model has been highly successful in explaining and predicting the behaviour of elementary particles.
Key points about the Standard Model:
- Particle Classification: The Standard Model classifies particles into two main categories: fermions and bosons.
- Fermions: Fermions are particles that make up matter. They are further categorized into quarks and leptons. Quarks are the building blocks of protons and neutrons, while leptons include electrons and neutrinos.
- Bosons: Bosons are force-carrying particles responsible for transmitting the fundamental forces. Examples include photons (electromagnetic force), gluons (strong nuclear force), and W and Z bosons (weak nuclear force).
- Fundamental Forces: The Standard Model explains the interactions between particles through the following fundamental forces:
- Electromagnetic Force: Mediated by photons, this force governs the interactions between charged particles.
- Strong Nuclear Force: Mediated by gluons, it binds quarks together to form protons, neutrons, and other particles.
- Weak Nuclear Force: Mediated by W and Z bosons, it is responsible for certain types of radioactive decay.
- Higgs Field and Higgs Boson: The Standard Model introduces the concept of the Higgs field, an energy field that permeates the universe. Particles acquire mass through their interaction with this field. The existence of the Higgs boson, a particle associated with the Higgs field, was confirmed in experiments at the Large Hadron Collider (LHC) in 2012.
Limitations and Open Questions:
While the Standard Model has been highly successful in describing particle interactions, it has some limitations:
- Gravity: The theory does not include a description of gravity, which is described by general relativity. Combining gravity with the other forces remains a challenge.
- Dark Matter and Dark Energy: The Standard Model does not account for dark matter and dark energy, which are believed to constitute a significant portion of the universe.
- Unification: The theory does not provide a unified description of all forces, including electromagnetism, weak nuclear force, and strong nuclear force.
