Grad Student’s Research Featured in EOS Journal

SOCORRO, N.M. February 26, 2016 – Graduate student Stipo Sentic recently published research that was later featured as a “research highlight” in the EOS Journal.

A doctoral student in atmospheric physics, Sentic’s original paper is “Diagnosing DYNAMO Convection with Weak Temperature Gradient Simulations” in the November issue of the Journal of Advances in Modeling Earth Systems. EOS featured Sentic’s work in January in an article headlined “Illuminating the Controls of Convection.”

His research advisor Dr. Sharon Sessions said she is proud of the work Sentic has put into the project. Sessions and Dr. Zeljka Fuchs are co-authors.

“He did a lot of independent tests of research,” Sessions said. “He was very persistent and we got to understand the models and were excited about the results. I thought the paper would be impactful, but I had no idea it would be selected for “Research Highlights’.”

Sentic’s publication examines how precipitation changes with temperature fluctuations in the tropics. His breakthrough is identifying observed relationships between various atmospheric variables, and demonstrating that their model could reproduce those relationships.  These relationships have previously been shown to be extremely important for understanding the development of hurricanes and typhoons. Sentic was specifically looking at the Madden-Julian Oscillation, the scientific name for a 30- to 60-day cycle of eastward moving clouds, rainfall, winds and pressure that traverses the planet.

Sentic worked with data collected during a 2011 field campaign. He started examining the data in 2014. This paper will eventually be the first chapter of his dissertation.

This sort of modeling is important, Sentic said, because it further explains the conditions that precede large-scale weather events.

“Hurricanes are an organization of clouds – from a disorganized state, clouds clump together,” he said. “That’s pretty important to understand, especially in a changing climate.”

Sentic earned his bachelor’s and master’s in meteorology and physical oceanography in Croatia. He expects to complete his Ph.D. in the spring of 2017.
