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 ...

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 ...

Utilization of satellite data in mesoscale modeling of severe weather [PDF]

The Visible Infrared Spin Scan Radiometer Atmospheric Sounder (VAS) data were used to model the 36 hour cyclogenesis period over the Pacific Ocean. Various combinations of VAS data, conventional radiosonde data, and gridded data from the National Weather

An Evaluation of MÉRA, a High-Resolution Mesoscale Regional Reanalysis

Journal of Applied Meteorology and Climatology, 2018
Met Éireann, the Irish Meteorological Service, has generated a very high resolution (2.5-km horizontal grid) regional climate reanalysis for Ireland called the Met Éireann Reanalysis (MÉRA).

Large‐eddy simulation with Lagrangian cloud modeling and large‐scale dynamics (L3$$ {\mathrm{L}}^3 $$) for studying the marine fog life cycle

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores the life cycle of marine fog using a novel L3$$ {\mathrm{L}}^3 $$ coupling method, which integrates large‐eddy simulation (LES), Lagrangian cloud modeling (LCM), and large‐scale dynamics (LSD). Simulations of two fog episodes observed during the FATIMA campaign revealed key insights into the fog's microphysical and dynamic ...

Jet stream related observations by MST radars [PDF]

, 1983
An overview of the jet stream and its observation by MST radar is presented. The climatology and synoptic and mesoscale structure of jet streams is briefly reviewed. MST radar observations of jet stream winds, and associated waves and turbulence are then

A Climatological Study of Western Mediterranean Medicanes in Numerical Simulations with Explicit and Parameterized Convection

Atmosphere, 2018
The semi-enclosed Mediterranean basin, surrounded by high mountains, is placed in a favorable location for cyclonic storms development. Most of these are extratropical cyclones of baroclinic and orographic origin, but occasionally, some low pressure ...

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 ...

Variational assimilation of Lagrangian data in oceanography [PDF]

, 2006
We consider the assimilation of Lagrangian data into a primitive equations circulation model of the ocean at basin scale. The Lagrangian data are positions of floats drifting at fixed depth.
