The paper on #Langmuir #turbulence with my former @UniRdg_Met student https://t.co/mweMQxCPFt and @ivyintheclouds is now published in an issue of JPO @ametsoc, totally open-access: https://t.co/wyX2On5Vv0

[Miguel Teixeira @MACTeixeira7]

Thanks are due to https://t.co/itctpElAle, https://t.co/Zam86aguhu and https://t.co/EuV7Bcr0zO

[Miguel Teixeira @MACTeixeira7]

Finally, the research of my student @UniRdg_Met https://t.co/MF6sZ4hiid is published in JPO @ametsoc, a collaboration with @ivyintheclouds. RDT inspires a physical parametrization of mixing due to ocean waves and stratification in the ocean mixed layer. https://t.co/mqBLiaQSiL

Our paper has been published (open access) in a QJRMS issue now : https://t.co/Wj8vOeb4n2

[Miguel Teixeira @MACTeixeira7]

In his 1st paper, my PhD student Hette Houtman, co-supervised with Sue Gray @UniRdg_Met, Peter Sheridan & Simon Vosper @MetOffice_Sci, shows in QJ @RMetS how to identify/characterize trapped lee waves from satellite images & high-resolution UKV simulations https://t.co/SHrQf7J9LZ

The final published version of our paper is out @AMSPublications: https://t.co/sopyVDIxIU

[Miguel Teixeira @MACTeixeira7]

In a collaboration including @DEMec_feup and @NanjingUnivers1, we show in #MonWeaRev @AMSPublications that accounting for nonhydrostatic effects in #orographic gravity #wave drag #parametrization improves WRF's forecast of Northeast China cold vortices: https://t.co/nZLHjnkpYc

This study extends these results to an arbitrary form of E(k) ~ k^n at low wavenumbers, with n integer. We show that if n = 1 then the velocity variance decays as <u^2> ~ x^(-2) and for any n>4, then <u^2> ~ x^(-4). But for n = 3, then perhaps unexpectedly <u^2> ~ x^(-4) ln(x).

[Miguel Teixeira @MACTeixeira7]

Our recent paper in @PhysRevE in collaboration with @istecnico https://t.co/XYmBlPRAi9 shows how the decay of velocity fluctuations outisde a #turbulence region with distance from the T/NT interface depends on different forms of the turbulence #spectrum's low wavenumber range.

[Miguel Teixeira @MACTeixeira7]

More recently, our own study https://t.co/IveOtuJi5K showed that for a Saffman spectrum with E(k) ~ k^2, the variance of the velocity fluctuations decays instead as <u^2> ~ x^(-3), which was confirmed by our DNS.

Check out this paper testing non-hydrostatic reduction of parametrized orographic gravity wave drag in MPAS: https://t.co/ijSgjEF5hx Could our physically-based approach become an alternative to cutting off drag contributions coming from orography narrower than a prescribed width?
