Frontiers in Earth Science, 2018 We discuss remote terrestrial influences on boundary layer air over the Southern Ocean and Antarctica, and the mechanisms by which they arise, using atmospheric radon observations as a proxy. Our primary motivation was to enhance the scientific community’

A Southern Hemispheric influence on the North Atlantic through a shallow atmospheric circulation response [PDF]
, 2017 Previous research has discussed the importance of meridional migrations of the North Atlantic Subtropical High (NASH) on U.S. precipitation patterns, but the mechanisms that control these meridionial migrations are virtually unknown.

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?
International Journal of Climatology, EarlyView.Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.

Characteristics of diabatically influenced cyclones with high wind damage potential in Europe
Quarterly Journal of the Royal Meteorological Society, EarlyView.Diabatic processes contribute, on average, 26% to the intensification of European winter storms, with diabatically driven cyclones exhibiting steeper deepening rates, stronger wind gusts, and increased precipitation. These storms are linked to enhanced warm conveyor belt (WCB) activity and develop in a warmer environment with elevated lower ...

GNSS ionospheric TEC and positioning accuracy during intense space and terrestrial weather events in B&H [PDF]
Geodetski Vestnik, 2019 To achieve the high accuracy in GNSS positioning, the various atmospheric effects on GNSS signals need to be mitigated, where the major part present the ionised atmosphere (ionosphere) and the neutral atmosphere (troposphere).

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Considerations on the dynamics of a cold spell over Greece
Meteorologische Zeitschrift, 1995 A cold spell was observed in March 1987 over Greece, which was characterised by extremely low temperatures and heavy snowfall. The dynamic and thermodynamic characteristics of this rather unusual event are investigated using ECMWF analyses.

Estimation of Atmospheric Path Delays in TerraSAR-X Data using Models vs. Measurements
Sensors, 2008 Spaceborne synthetic aperture radar (SAR) measurements of the Earth’s surface depend on electromagnetic waves that are subject to atmospheric path delays, in turn affecting geolocation accuracy.

Solar influences on dynamical coupling between the stratosphere and troposphere [PDF]
, 2006 We use a simplified atmospheric general circulation model (AGCM) to investigate the response of the lower atmosphere to thermal perturbations in the lower stratosphere.

Impact of small‐scale gravity waves on tracer transport
Quarterly Journal of the Royal Meteorological Society, EarlyView.We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.
