A new technique for evaluating mesospheric momentum balance utilizing radars and satellite data by D. J. Frame, D. J. Frame, D. J. Frame, B. N. Lawrence, G. J. Fraser, R. A. Vincent, A. Dudhia

“…The technique allows the calculation of the residual terms in the momentum balance which are usually attributed to the effects of breaking gravity waves. Although the results are inconclusive above Adelaide, this method produces values of zonal and meridional residual accelerations above Christchurch which are consistent with expectation. …”

Characteristics and sources of gravity waves observed in noctilucent cloud over Norway by T. D. Demissie, P. J. Espy, N. H. Kleinknecht, M. Hatlen, N. Kaifler, G. Baumgarten

“…However, a unique population of fast, short wavelength waves propagating towards the SW is observed in the NLC, which is consistent with transverse instabilities generated in situ by breaking gravity waves (Fritts and Alexander, 2003). The relative amplitude of the waves observed in the NLC Mie scatter have been combined with ray-tracing results to show that waves propagating from near the tropopause, rather than those resulting from secondary generation in the stratosphere or mesosphere, are more likely to be the sources of the prominent wave structures observed in the NLC. …”

Comparisons of wave dynamics in Hodgkin-Huxley and Markov-state formalisms for the sodium (Na) channel in some mathematical models for human cardiac tissue by Mahesh Kumar Mulimani, Alok Ranjan Nayak, Rahul Pandit

“…Furthermore, these changes lead to different excitation behaviors in cardiac tissue; specifically, two of the WT models show stable spiral waves, but the other one shows meandering and transiently breaking spiral waves. Our results are based on extensive direct numerical simulations of waves of electrical activation in these models, in two- and three-dimensional (2D and 3D) homogeneous simulation domains and also in domains with localized heterogeneities, either obstacles with randomly distributed inexcitable regions or mutant cells in a wild-type background. …”

Physics-Based Learning Models for Ship Hydrodynamics by Weymouth, Gabriel D., Yue, Dick K. P.

“…To illustrate the versatility and efficacy of PBLM, we present three wave-ship interaction problems: 1) at speed waterline profiles; 2) ship motions in head seas; and 3) three-dimensional breaking bow waves. PBLM is shown to be robust and produce error rates at or below the uncertainty in the generated data at a small fraction of the expense of high-resolution numerical predictions.…”

Relationship between turbulent energy dissipation and gas transfer through the air–sea interface by Dongliang Zhao, Nan Jia, Yuanxu Dong

“…Turbulent kinetic energy (TKE) near the air–sea interface is significantly intensified by breaking wind waves. By analyzing various models, we found that the TKE dissipation rate was explicitly linearly related to wind speed and dependent on wave age, with powers ranging from –2.36 to 4.0. …”

Rocket measurements of positive ions during polar mesosphere winter echo conditions by A. Brattli, T. A. Blix, Ø. Lie-Svendsen, U.-P. Hoppe, F.-J. Lübken, M. Rapp, W. Singer, R. Latteck, M. Friedrich

“…The PMWE are therefore clearly indicative of turbulence, and the data are consistent with the turbulent dissipation of breaking gravity waves. We estimate a lower limit for the turbulent energy dissipation rate of about 10^−2 W/kg in the upper (72 km) layer.…”

Towards a more comprehensive assessment of the intensity of historical European heat waves (1979–2019) by Florian N. Becker, Andreas H. Fink, Peter Bissolli, Joaquim G. Pinto

“…Abstract Europe has been affected by record‐breaking heat waves in recent decades. Using station data and a gridded reanalysis as input, four commonly used heat wave indices, the heat wave magnitude index daily (HWMId), excess heat factor (EHF), wet‐bulb globe temperature (WBGT) and universal thermal climate index (UTCI), are computed. …”

Role of vertical and horizontal mixing in the tape recorder signal near the tropical tropopause by A. A. Glanville, T. Birner

“…Contrasting the results between pressure and isentropic coordinates allows for further insights into quasi-adiabatic vertical mixing, e.g., associated with overshooting convection or breaking gravity waves. Horizontal mixing, which takes place primarily along isentropes due to Rossby wave breaking, is captured more consistently in isentropic coordinates. …”
