Surface-Forced Variability in the Nordic Seas Overturning Circulation and Overflows
(Journal article; Peer reviewed, 2023)Water mass transformation in the Nordic Seas and the associated overflow of dense waters across the Greenland-Scotland Ridge (GSR) acts to maintain the lower limb of the Atlantic meridional overturning circulation. Here, ... -
Tidally Forced Lee Waves Drive Turbulent Mixing Along the Arctic Ocean Margins
(Journal article; Peer reviewed, 2020)In the Arctic Ocean, limited measurements indicate that the strongest mixing below the atmospherically forced surface mixed layer occurs where tidal currents are strong. However, mechanisms of energy conversion from tides ... -
Transition in Optical and Radio Features During the Early Development of Negative Intracloud Leader
(Journal article; Peer reviewed, 2022)What happens when the upward in-cloud (IC) breakdown transitions into horizontally expanding extension? Optical observations of this transition in IC lightning have not previously been reported. We identify the radio and ... -
Tropical Atmospheric Response of Atlantic Niños to Changes in the Ocean Background State
(Journal article; Peer reviewed, 2023)Since the 1970s, Atlantic Niños during boreal summer have been linked to Pacific La Niñas the following winter. Earlier studies have explained the appearance of the Atlantic-Pacific teleconnection with changing Atlantic ... -
Understanding differences in North Atlantic poleward ocean heat transport and its variability in global climate models
(Journal article; Peer reviewed, 2021)The ocean heat transport from the North Atlantic to the Barents Sea impacts the sea ice extent and the energy budget of the Arctic. The analyzed climate models from the fifth (CMIP5) and sixth Coupled Model Intercomparison ... -
Wavefield Migration Imaging of Moho Geometry and Upper Mantle Structure Beneath Southern New England
(Journal article; Peer reviewed, 2022)The crust and upper mantle beneath the New England Appalachians exhibit a large offset of the Moho across the boundary between Laurentia and accreted terranes and several dipping discontinuities, which reflect Paleozoic ... -
Will Climate Change Impact Polar NOx Produced by Energetic Particle Precipitation?
(Journal article; Peer reviewed, 2020)Energetic electron precipitation (EEP) is an important source of polar nitrogen oxides (NOx) in the upper atmosphere. During winter, mesospheric NOx has a long chemical lifetime and is transported to the stratosphere by ...
