- La Niña Officially Ends: NOAA confirms the end of the recent La Niña event in the tropical Pacific Ocean.
- Transition to ENSO-Neutral: The climate system is now in ENSO-neutral conditions, expected to persist through summer and with a high chance into autumn.
- ENSO Explained: ENSO involves changes in sea-surface temperatures (SST) in the central and eastern tropical Pacific, influencing global weather.
- ENSO Phases:
- El Niño: Warmer-than-usual SSTs.
- La Niña: Cooler-than-usual SSTs.
- ENSO-Neutral: Neither El Niño nor La Niña dominates.
- March 2025 Observations: SST anomalies in the Niño-3.4 region reached -0.01°C, above the La Niña threshold.
- Why This Matters: ENSO significantly affects global agriculture and weather patterns. El Niño weakens monsoon rains, while La Niña enhances them.
- Climate Change Impact: Studies suggest increased frequency of extreme El Niño events due to warmer Pacific waters.
- Indian Ocean Dipole (IOD): A positive IOD can offset El Niño’s impact on the monsoon.
- Trade Winds: Persisting trade winds initially indicate a transition in process.
Mount Spurr
- Increased Seismic Activity: Dozens of mini-earthquakes, including “swarms,” have been recorded at Mount Spurr, indicating rising magma and increased pressure.
- Eruption Threat: Scientists fear a major eruption is imminent due to the increased seismic activity and elevated gas emissions.
- Potential Ash Cloud: An eruption could be explosive, with ash plumes reaching up to 50,000 feet. Each explosive event may last 3-4 hours.
- Anchorage on Alert: Anchorage, with over 300,000 residents, is on emergency alert (Level 2) and is located 81 miles from the volcano.
- Community Preparedness: Residents are stocking up on essentials like food, water, pet supplies, N95 masks, and protective gear.
- Rising Unrest: Concerns began in April 2024, with a significant increase in weekly quakes and gas emissions by October 2024.
- Gas Emissions: Elevated carbon dioxide and sulfur dioxide emissions signal magma heating water and gas below the surface.
- Volcanic Tremor as Indicator: Sustained volcanic tremor would be the next sign of an imminent eruption.
- Last Eruption Impact: The 1992 eruption from Crater Peak (a side vent) blanketed Anchorage in ash and shut down the airport.
- Most Likely Eruption Site: Experts expect the next eruption to likely occur from Crater Peak again.
- Pet Preparedness: Pet stores are experiencing high demand for protective goggles and respirators for pets.
- Monitoring: The National Transportation Safety Board and US Geological Survey are closely monitoring the volcano.
KATRIN and Neutrino Mass
- Neutrinos are fundamental, lightweight particles: Electrically neutral, produced in processes like radioactive decay and nuclear reactions (e.g., in the sun). Their mass is unknown but tiny, less than a millionth of an electron’s mass.
- KATRIN’s Goal: The Karlsruhe Tritium Neutrino experiment in Germany aims to precisely measure the mass of the electron antineutrino.
- How KATRIN Works: Studies tritium decay, focusing on the emitted electron’s energy, which is affected by the neutrino’s mass. Measuring electron energies helps estimate the neutrino’s mass upper limit.
- Latest KATRIN Finding: Reduced the upper limit of the neutrino mass to less than 0.45 electron volts (eV). This is a significant improvement (nearly 50% reduction) based on precise measurements of 36 million electrons from tritium decay.
- Significance of Neutrino Mass Measurement: Crucial for understanding cosmology (dark matter/dark energy) and developing theories beyond the Standard Model of particle physics.
- India’s Contribution: The proposed India-based Neutrino Observatory (INO) in Tamil Nadu will focus on studying atmospheric neutrinos.
