Cyclone Intensity: eddies, heat potential, and more

(0)
August 7, 2021

When cyclones pass over eddies formed by ocean currents, energy can be transferred between eddies and cyclones. Researchers from IIT Bhubaneswar investigate the dynamics of 60 cyclones from Indian Ocean to elicit the relationships between cyclones and eddies.

Groundwater Quality Assessment: Udhampur District

As Udhampur district is becoming more urbanised, the groundwater resources may become unsustainable and contaminated. Researchers from the University of Kashmir draw a baseline for monitoring groundwater quality.

LIGO overcomes seismic noise

LIGO can detect gravitational waves caused by celestial events millions of kilometres away. But quakes caused by events a few kilometres under the earth can mess up the results. Read on to see how scientists overcame the problem.

Gondwana Sandstones of Arunachal

Researchers from the Dibrugarh University and the Geological Survey of India dig up the past history of the Gondwana sandstones in Arunachal Pradesh. They enquire into the conditions when these sandstones were deposited.

Local Magnetic Field: Earthquake precursor?

The disturbances in the horizontal component of the earth’s magnetic field are not the same in different magnetic field stations. Researchers from the University of Kerala suggest that monitoring the correlations in the ratio of signals from magnetic field stations can help forecast earthquakes.

Groundwater Recharge Zones: Machines learn to predict

Which are the best areas to construct groundwater recharge structures to overcome the outcome of overexploitation of groundwater resources? How can we leverage on machine learning to make sense of the abundance of data on the factors that determine groundwater recharge? And map the recharge potential? N Sadhasivam from the Bharathidasan University explores.

Panchi Nala Glacier: signs of degeneration

Panchi Nala glacier in the Bhaga River basin of the Lahaul-Spiti District, Himachal Pradesh has been degenerating rapidly. It is time to take action, points out scientists from the Ministry of Earth Sciences and Wadia Institute of Himalayan Geology.

Monsoon Revival Over India Skipping North India?

Monsoon over India has seen a revival after 2000. But Uttar Pradesh and Bihar are left out. Why? Ramesh Kumar Yadav and Roxy Mathew Koll from the IITM Pune say that the answer may lie in the warming of eastern equatorial Indian Ocean and Rossby gyres.

Dating Elephanta Magmatism: Age, duration and evolution

Researchers from the St Xavier’s College, Mumbai, IIT Bombay and the Bhabha Atomic Research Centre find that the volcanism in Elephanta islands predates the volcanism in Mumbai by more than 3 million years

Estimating Rainfall: A comparison of satellite data products

There are various satellite data products that can help predict rainfall. Which one is best for the purpose? M. Venkatarami Reddy, and Imranali M. Momin from the National Centre for Medium Range Weather Forecasting, and Ashis K. Mitra and D. S. Pai from the India Meteorological Department investigates.
