Personal Profile
Sidha Sankalpa Moharana
I am Sidha Sankalpa Moharana. I am currently a research scholar pursuing Ph.D. in Atmosphere and Ocean Sciences in the School of Earth, Ocean and Climate Sciences, Indian Institute of Technology (IIT) Bhubaneswar. My research interest can broadly be summerised as Ocean - Atmosphere Interactions. My current research includes the investigation of variability in geophysical parameters driving the recent increase in global hurricane activity .

The electric coupling that exists between the lower atmosphere and the upper atmosphere was studied in detail using a case study of Cyclone Fani, an Extremely Severe Cyclonic Storm and the most intense of the 2019 Indian Ocean Cyclone Season. The unique meteorological properties which enabled ESCS Fani to survive for a long 30 hours after landfall, as well as its intense electrical discharges which disturbed the Ionosphere via atmospheric gravity waves, were investigated using VLF waves, GPS-TEC datasets, GLD360 and WWLLN datasets.

The occurrences of electrical discharges over the cloud systems and sometimes reaching the base of Ionosphere, known as Transient Luminous Events or TLEs were investigated over the Indian subcontinent. 10 such TLEs (9 Sprites and 1 Gigantic Jet) over the central Indian region were characterized along with their parent thunderstorm properties.
