Rapid versus slow intensification of idealized tropical cyclones using soundings from reanalysis
Quarterly Journal of the Royal Meteorological Society, EarlyView.Climatologically averaged environmental wind and moisture around intensifying tropical cyclones are used in an idealized model to further discriminate differences between ensembles of rapidly (RI) and slowly (SI) intensifying storms. On average, RI storms have lower vertical tilt, are more axisymmetric, and less ventilated at onset than SI storms, and ...

, 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 ...

Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals [PDF]
, 2014 We demonstrate that the global fields of temperature, humidity and geopotential heights admit a nearly sparse representation in the wavelet domain, offering a viable path forward to explore new paradigms of sparsity-promoting data assimilation and ...

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

Atmospheric Circulation of Brown Dwarfs: Jets, Vortices, and Time Variability [PDF]
, 2014 A variety of observational evidence demonstrates that brown dwarfs exhibit active atmospheric circulations. In this study we use a shallow-water model to investigate the global atmospheric dynamics in the stratified layer overlying the convective zone on

Weather systems and their contribution to seasonal rainfall in Australia
Quarterly 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 ...

Height determination using GPS data, local geoid and global geopotential models [PDF]
, 1995 Orthometric heights are normally derived using the spirit levelling. This requires the spirit level equipment to be set up from point 10 point along a levelling line which is a time consuming and tedious task.

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

Quarterly 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 ...
