Summary: The Global Hawk, a drone or unmanned aircraft system, has been used since 2010 to gather data to improve weather forecasts. The Global Hawk can release dropsondes that measure temperature, pressure, humidity, and wind up to four times every second, starting at an altitude of up to 60,000 feet until it falls to the … Continue reading Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications
Nikolaus was born in Cape Town, South Africa, and moved to the US at the age of 8.He is now going into his Senior year at Embry-Riddle Aeronautical University as a double major in Meteorology and Computational Mathematics. Nikolaus, a NOAA Hollings Scholar, began his virtual Hollings summer internship with Hui Christophersen and Jason Sippel in … Continue reading Hollings Scholar Nikolaus Rentzke profiled in a special intern edition of NOAA Connections
During the summer of 2020, NOAA’s Atlantic Oceanographic and Meteorological Laboratory virtually hosted two Ernest F. Hollings Undergraduate Scholarship recipients, Samantha Michlowitz and Nikolaus Rentzke. Recently, they presented seminars of their work to AOML’s Hurricane Research Division. Their summer project presentations will take place during NOAA's final presentation week in early August. Michlowitz, a rising … Continue reading HRD’s Hollings Scholars present their student seminars

Dr. Cohen presented a seminar titled “Gradient Non-Balance: A new approach for the outflow at the top of Tropical Cyclones: Theory, models and observations". ABSTRACT: The gradient non-balance is a flow-regime in which the gradient wind balance has no solutions or a given pressure map. This occurs only around a high pressure center, when the … Continue reading HRD Seminar – Dr. Yair Cohen, California Institute of Technology – 13 November 2018
