Observations of a frontal–trough merger over a wildfire, Queensland, Australia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Observations are presented of the meteorology of a frontal–trough merger in subtropical Australia which impacted a wildfire. An elevated nocturnal mixed layer above approx. 2500 m with increasing moisture with height was identified as the source of instability that resulted in the formation of elevated storms along a 300‐km frontal–trough boundary ...

A Shallow-water Model Exploration of Atmospheric Circulation on Sub-Neptunes: Effects of Radiative Forcing and Rotation Period

open access: yesThe Planetary Science Journal, 2023
Sub-Neptune-type exoplanets are abundant in our Galaxy yet have no solar system analogs. They exist in a broad range of stellar forcing and rotational regimes that are distinctly different from solar system planets and more commonly studied hot Jupiters.

Weakening and Shifting of the Saharan Shallow Meridional Circulation During Wet Years of the West African Monsoon

open access: yes, 2017
The correlation between increased Sahel rainfall and reduced Saharan surface pressure is well established in observations and global climate models, and has been used to imply that increased Sahel rainfall is caused by a stronger shallow meridional ...

Weather systems and their contribution to seasonal rainfall in Australia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Closed low‐pressure systems (including tropical cyclones) contribute to most of the summer rainfall over northern Australia. In southern Australia, winter rainfall is mainly associated with Rossby wave breaking, cyclones, and warm conveyor belts. Summer and winter rainfall patterns can be explained by changes in large‐scale flow and associated weather ...

The Evaluation of High-Degree Geopotential Models for Regional Geoid Determination in Turkey

open access: yes, 2017
High-degree geopotential models of spherical harmonic coefficients are used for modelling the exterior gravity field of the Earth. These coefficients are derived from satellite tracking data, altimeter data, and terrestrial and airborne gravity data ...

How sensitive are Sahelian mesoscale convective systems to cold‐pool suppression?

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Cold pools are a ubiquitous feature of mesoscale convective systems (MCSs) with important upscale impacts on West African climate, but their role in the maintenance of tropical MCSs remains debated. Using a 40‐day model with explicit convection and no rainfall evaporation, we show that cold pools do not play a primary role in Sahel MCS development or ...

Estimating the geopotential value W0 of the local geoid based on data from local and global normal heights of GPS/leveling points in Vietnam

open access: yesGeodesy and Cartography, 2013
Currently, the determination of geopotential value W0 of local geoid that best fits local mean sea level at the Zero Tide Gauge Station is getting important in building the National Geoid-Based Vertical System.

Satellite techniques for determining the geopotential for sea-surface elevations [PDF]

open access: yes, 1984
Spaceborne altimetry with measurement accuracies of a few centimeters which has the potential to determine sea surface elevations necessary to compute accurate three-dimensonal geostrophic currents from traditional hydrographic observation is discussed ...

Contrasting impacts of two mesoscale cyclones on the South Shetland Islands' glaciers, northern Antarctic Peninsula

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Parallel-in-Time Multi-Level Integration of the Shallow-Water Equations on the Rotating Sphere

open access: yes, 2019
The modeling of atmospheric processes in the context of weather and climate simulations is an important and computationally expensive challenge. The temporal integration of the underlying PDEs requires a very large number of time steps, even when the ...
