An Explanation of the Poleward Mass Flux in the Stratosphere

Atmosphere
This paper offers a new perspective on the explanation of the poleward mass flux in the stratosphere. This mass flux represents the upper leg of the so-called Brewer–Dobson circulation. This new perspective is based on the following hypothesis.

Planetary Waves over Antarctica

, 2022
Denne oppgaven undersøker hypotesen lagt frem av Alan Plumb i 1989 med formålet om å forklare nedkjølingen midtvinter i mesosfæren over Antarktis. Fundamentet til denne hypotesen bygger på at de planetarisk bølgene ikke forplanter seg oppover i atmosfæren da vinden når en styrke som går over den øvre grensen til Charney-Drazin kriteriet.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Dynamic Impact of the Southern Annular Mode on the Antarctic Ozone Hole Area

Remote Sensing
This study investigates the impact of dynamic variability of the Southern Hemisphere (SH) polar middle atmosphere on the ozone hole area. We analyze the influence of the southern annular mode (SAM) and planetary waves (PWs) on ozone depletion from 19 ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Nonlinear Interactions of Planetary‐Scale Waves in Mesospheric Winds Observed at 52°N Latitude and Two Longitudes

Geophysical Research Letters
Nine‐years of mesospheric wind measurements, from two meteor radars at 52°N latitude, were analyzed to study planetary waves (PWs) and tides through estimating their zonal wavenumbers.

Impact of Polar Vortex Modes on Winter Weather Patterns in the Northern Hemisphere

Atmosphere
This study is an additional investigation of stratosphere–troposphere coupling based on the recent stratospheric winter descriptions in five distinct modes: January, February, Double, Dynamical, and Radiative. These modes, established in a previous study,
