Marine fog comes below focus in new five-year examine

Researchers on the College of Notre Dame will lead a five-year examine to enhance the elemental understanding, detection and predictability of marine sea fog.

Harindra Joseph Fernando, the Wayne and Diana Murdy Endowed Professor within the Departments of Civil and Environmental Engineering and Earth Sciences and Aerospace and Mechanical Engineering, will function principal investigator of the undertaking referred to as Fog and Turbulence Interactions within the Marine Environment (FATIMA).

“The overall familiarity with fog is its disruption of societal capabilities akin to transportation, delaying journey and inflicting hazardous circumstances for commuters,” stated Fernando. “Fog also can impede communications and intrude with high-energy laser, free-space optics and distant detection functions which are essential to authorities and safety operations—and but, it stays probably the most poorly studied elements of meteorology.”

FATIMA will encompass two 30-day discipline campaigns, one to be carried out on Sable Island within the Canadian Atlantic and one off the coast of South Korea within the Yellow Sea. A further ice-fog experiment can be carried out in Barrow, Alaska.

Fernando’s group at Notre Dame will lead the examine together with FATIMA’s discipline campaigns and theoretical research. The undertaking’s emphasis on marine fog will search to achieve elementary understanding of how fog—which consists of water droplets and/or ice crystals within the decrease ambiance—kinds over shallow seas. The group can even have a look at the dynamics of coastal ice fog.

Taking a multidisciplinary strategy, researchers will deploy modern instrumentation throughout every discipline marketing campaign; seize atmospheric turbulence all the way down to its smallest scales, temperature and moisture fluctuation readings; and conduct theoretical and numerical evaluation to study extra about how fog is generated and establish the variations between fog and low-level cloud cowl. The final word aim is to enhance sea fog predictability.

The $7.5 million examine is funded by the U.S. Division of Protection’s Multidisciplinary College Analysis Initiative. Co-principal investigators embody Qing Wang on the Naval Postgraduate Faculty, Clive Dorman on the College of California San Diego and Scripps Establishment of Oceanography, Eric Pardyjak on the College of Utah and Lian Shen on the College of Minnesota. For the fiscal yr 2021 Multidisciplinary College Analysis Initiative competitors, the DOD solicited proposals in 26 subject areas necessary to DOD and the army companies. From a merit-based assessment of the 298 proposals obtained, a panel of specialists narrowed the proposals to a subset from which the 25 finalists had been chosen.

Fernando is an affiliated member of Notre Dame’s Environmental Change Initiative and Notre Dame Power.
