High resolution numerical simulation of a nocturnal mesoscale convective system: Comparison with pecan observations
Nighttime convective storms produce a significant portion of warm season precipitation across the Great Plains region of the United States. The PECAN (Plains Elevated Convection at Night) project was designed to improve our understanding of how these storms can develop and maintain themselves in …

Numerical simulation of a mesoscale convective system over the east coast of South Africa
… This heavy rainfall was associated with a mesoscale convective system (MCS) that initiated through small convective storms beginning early in the afternoon on 11 February 2005 and eventually decayed in the early morning hours on the 12th. The high-lying topography of the eastern escarpment …

Analysis Of A Parallel Stratiform Mesoscale Convective System During The Midlatitude Continental Convective Clouds Experiment
<p>During the Midlatitude Continental Convective Clouds Experiment, a PS MCS traversed north-central Oklahoma on 11 May 2011. In-situ measurements of the stratiform precipitation region were obtained from six horizontal flight legs flow by the University of North Dakota Citation II Weather Research …

Source air feeding convection within a nocturnal mesoscale convective system during the evolution from surface-based to elevated convection
… observed, the mechanisms that allow nocturnal mesoscale convective systems (MCSs) to persist are still not well understood. On 9 August 2014 at approximately 2000 UTC, a regime of upslope flow owing to a weak shortwave impulse in the lee of the Rocky Mountains spawned a convective complex near …

The influence of environmental conditions and cold pool generation on surface-based vs. elevated convection in a nocturnal mesoscale convective system
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-03-28 without embargo terms

How does terrain influence the upscale convective growth of orographic deep moist convection?
… that some of the world’s most intense deep convective storms occur near the Sierras de Córdoba, Argentina, South America. A ground-based radar climatology during two austral spring and summer seasons (2015–2017) revealed that most of the storms were multicellular and initiated most …

Improving Convective Permitting Model Simulations of Extreme Precipitation using Object-Based Tracking and Data Assimilation
This dissertation explores the improvement of mesoscale convective system (MCS) tracking and forecasting during severe weather episodes over the central and southern US using high-resolution numerical simulation and advanced data assimilation.In Appendix A, we evaluate the performance of a km-scale …

Rain and RELAMPAGO: analysis of the deep convective storms of central Argentina
… South America, which has some of the strongest convective storms on Earth. Seasonal and dirunal distribution are compared, with similar seasonal distributions between the datasets but at the diurnal scale MERRA2 and ERA5 show more afternoon events than TRMM and IMERG. Thermodynamic environments …

An Investigation of the Role of Land-Atmosphere Interactions on Nocturnal Convective Activity in the Southern Great Plains
… numerical simulations of an intense nocturnal mesoscale convective system (MCS) on 19-20 June 2007 with the Weather Research and Forecasting (WRF V3.3) model. High-resolution nested simulations were conducted using realistic and idealized land-surfaces and two different planetary boundary layer …

Observation and simulation of mid-latitude ice clouds
… sphere. The ice clouds in various weather systems from polar to equator have been sampled using aircraft equipped with in-situ probes in the past several decades and plenty of datasets are available, thus the comparison of observed and modeled PSDs using the parameters of gamma distribution …
