Numerical Simulations of a Midlatitude Squall Line
… the observed structure of a typical midlatitude squall line. The basic simulations described in this report were made using common temperature and moisture profiles in the vertical, and emphasis was placed on varying the microphysics and the vertical wind shear. The temperature and moisture …

Numerical simulation of a squall line along a cold front
The 10-11 June 1985 squall line system with trailing stratiform precipitation observed during the Oklahoma PRE-STORM project has been numerically simulated using the three-dimensional cloud resolving nonhydrostatic COMMAS (COllaborative Model for Multiscale Atmospheric Simulation) model.

Interaction of an upper-tropospheric jet with a squall line originating along a cold frontal boundary
On 8 June 2003, an expansive squall line along a surface cold frontal boundary was sampled during the Bow Echo and Mesoscale Convective Vortex Experiment. The Naval Research Laboratory P-3 aircraft and the National Oceanic and Atmospheric Administration P-3 aircraft simultaneously sampled the …

A study of the effect of Lake Erie on deep convective systems
… lake. Additionally, a study of the 26 July 2005 squall line case was conducted to identify processes by which the squall line interacted with a cool MBL, as well the effects on the convection caused by the movement from land to water. Results of the climatological study identified 89 cases of …

Application of the Weather Research and Forecasting (WRF) Model to Simulate a Squall Line: Implications of Choosing Parameterization Scheme Combinations and Model Initialization Data Sets
<p>On January 29-30, 2008 a squall line of thunderstorms moved through the Ohio Valley resulting in four deaths and one injury. Such events highlight the importance of accurate forecasting for public safety. Mesoscale Modeling plays an important role in any forecast of a potential squall line. The …

Modeling study of tropical nonsquall and squall clusters
… the dynamical differences between non-squall and squall line convection in the tropics. Two-dimensional simulations with cold-pool dynamics indicate that the simulated convective system propagates as a slow-moving multicellular squall line, in contrast to the nearly stationary observed …

Dusty gust fronts and their contributions to long-lived convection in West Africa/
… kind of West African MCS - the westward-moving squall line. An automated method is developed to quantify lightning within an MCS (using a Lagrangian method to follow the storm). Continuous "stripes" of lightning activity, caused by squall lines, emerge in lightning Hovmollers over West Africa …

Tropical squall lines of the Arizona monsoon.
Squall lines possessing nearly all the characteristics of tropical squall lines occasionally develop during the summer monsoon over southern Arizona and northwestern Mexico. Initial thunderstorm formation is over the mountains along the Continental Divide in the late afternoon. Satellite imagery, …

Observed microphysical characteristics and inferred thermodynamic processes contributing to the structure, evolution, and maintenance of nocturnal elevated mesoscale convective systems
… several conforming to the classic leading-line/trailing-stratiform mode, and others conforming to the parallel stratiform, leading stratiform, and nonlinear system modes. In one case observations were made in the stratiform region trailing a frontal squall line. Multiple-Doppler syntheses …

Fusion of observations from C-band polarimetric radar and S-band profiler radar during a convective storm
… site. A convective storm event characterized by squall lines is investigated. Within the squall line region, the presence of partially melted ice particles led to significant attenuation of the radar signal at C-Band, resulting in reduced reflectivity (Z). To address this issue, a conventional …

Analyses of quasi-linear convective system tornado characteristics, environments, and genesis mechanisms
… proposed mechanisms of tornadogenesis in quasi-linear convective systems (QLCSs), namely, tilting and stretching (T&S) and HSI and stretching (H&S). This research then sought to investigate differences and similarities between the characteristics of the T&S- and H&S- associated tornadoes and …

An Investigation of the Role of Land-Atmosphere Interactions on Nocturnal Convective Activity in the Southern Great Plains

Toward assessing the effects of aerosols on deep convection: a numerical study using the WRF-Chemistry model
