Different Representation of Mesoscale Convective Systems in Convection-Permitting and Convection-Parameterizing NWP Models and Its Implications for Large-Scale Forecast Evolution

Atmosphere, 2019
Representing mesoscale convective systems (MCSs) and their multi-scale interaction with the large-scale atmospheric dynamics is still a major challenge in state-of-the-art global numerical weather prediction (NWP) models.

Sea breeze: Induced mesoscale systems and severe weather [PDF]

Sea-breeze-deep convective interactions over the Florida peninsula were investigated using a cloud/mesoscale numerical model. The objective was to gain a better understanding of sea-breeze and deep convective interactions over the Florida peninsula using

Impact of Joint Assimilating AWS and Radar Observations on the Analysis and Forecast of a Squall Line with Complex Terrain

Remote Sensing
Based on the WRF-3DVar system, this study investigates the impacts of assimilating radar and automatic weather station (AWS) observations, both independently and jointly, for a squall line case that occurred over complex terrain in China on 30 May 2024 ...

Practical rare event sampling for extreme mesoscale weather

, 2019
Extreme mesoscale weather, including tropical cyclones, squall lines, and floods, can be enormously damaging and yet challenging to simulate; hence, there is a pressing need for more efficient simulation strategies.

Urban Impacts on Convective Squall Lines over Chicago in the Warm Season—Part I: Observations of Multi-Scale Convective Evolution

Atmosphere
In this study, our aim is to diagnose how two quasi-linear convective systems (QLCS) are organized so one can determine the possible role of the city of Chicago, IL, USA, in modifying convective precipitation systems.

Precipitation growth in convective clouds [PDF]

Analytical solutions to the equations of both the growth and motion of hailstones in updrafts and of cloud water contents which vary linearly with height were used to investigate hail growth in a model cloud.

Joint distribution of lightning and wind speed and its impact on the transmission system

Frontiers in Energy Research
Distribution of lightning plays a key role in lightning protection of transmission lines. The design of wind deviation under lightning overvoltage of the transmission tower is an empirical parameter in the transmission line design code.

Dynamics of a developing squall line

Meteorologische Zeitschrift, 1994
Four kinds of severe, mesoscale convective-line development have been identified. One type, back-building, involves the periodic appearance of a new cell upstream of the existing line. Ultimately this new cell merges with the line, as new cells continue to form in the upstream direction.
