Influence of Lead width on the Turbulent Flow Over Sea Ice Leads: Modeling and Parametrization
; ; ; ; (Journal of Geophysical Research: Atmospheres, 2020)
A new turbulence parametrization is developed for a non-eddy-resolving microscale model to study the effects of leads (elongated open-water channels in sea ice) of different width on the polar atmospheric boundary layer ... -
Modelling and parametrization of the convective flow over leads in sea ice and comparison with airborne observations
; ; Schmitt, Amelie U.; Hartmann, Jörg (Quarterly Journal of the Royal Meteorological Society, 2021-02-07)
A non‐eddy‐resolving microscale model is applied to simulate convection over three different leads (elongated channels in sea ice), which were observed by aircraft over the Arctic Marginal Ice Zone in 2013. The study aims ... -
Sensitivity to changes in the surface‐layer turbulence parameterization for stable conditions in winter: A case study with a regional climate model over the Arctic
;; ; ; ; ; ; ; (Atmospheric Science Letters, 2021-08-24)
The modeling of the atmospheric boundary layer over sea ice is still challenging because of the complex interaction between clouds, radiation and turbulence over the often inhomogeneous sea ice cover. There is still much ... -
The Two‐Energies Turbulence Scheme Coupled to the Assumed PDF Method
; ; (Journal of Advances in Modeling Earth Systems, 2022-05-14)
An update of the two‐energy turbulence scheme is presented, the 2TE + APDF scheme. The original version of the two‐energy scheme is able to successfully model shallow convection without the need of an additional parameterization ... -
Toward Parametrization of Precipitating Shallow Cumulus Cloud Organization via Moisture Variance
; ; (Journal of Geophysical Research: Atmospheres, 2021-07-30)
The influence of the initial vertical moisture profile on precipitating shallow cumulus cloud organization in terms of the column‐averaged moisture variance is investigated using large‐eddy simulations. Five idealized ...
