Polar mesosphere summer echoes (PMSE) are very strong radar echoes primarily studied in
the VHF wavelength range from altitudes close to the polar summer mesopause. Radar …

We describe and compare idealized high‐resolution simulations of turbulence arising due to
Kelvin‐Helmholtz shear instability and gravity‐wave breaking, believed to be the two major …

Triggered by recent experimental evidence showing that some parts of the Cho et al.[1992]
theory describing electron diffusion in the vicinity of charged aerosol particles cannot be …

Turbulence parameters in the tropo-stratosphere are analyzed using high-resolution balloon
temperature measurements collected during the MUTSI (MU radar, Temperature sheets and …

In summertime, layers of icy particles form in the high‐latitude mesopause region, causing
the phenomena of noctilucent clouds and polar mesosphere summer echoes. We study the …

A high–Reynolds number direct numerical simulation (DNS) is employed to explore the
instability and turbulence dynamics accompanying an idealized multiscale flow that …

Four idealized direct numerical simulations are performed to examine the dynamics arising
from the superposition of a monochromatic gravity wave (GW) and sinusoidal linear and …

New capabilities for imaging small-scale instabilities and turbulence and for modeling
gravity wave (GW), instability, and turbulence dynamics at high Reynolds numbers are …

We present new sensitivity experiments that link observed anomalies of the mesosphere
and lower thermosphere at high latitudes during the MaCWAVE/MIDAS summer program …

An anelastic numerical model is employed to explore the dynamics of gravity waves (GWs)
