Shear‐Convection Interactions and Orientation of Tropical Squall Lines [PDF]
Geophysical Research Letters, 2022 Abstract Squall lines are known to be the consequence of the interaction of low‐level shear with cold pools associated with convective downdrafts. Also, as the magnitude of the shear increases beyond a critical shear, squall lines tend to orient themselves.

Extreme Precipitation in Tropical Squall Lines
Journal of Advances in Modeling Earth Systems, 2023 Squall lines are substantially influenced by the interaction of low‐level shear with cold pools associated with convective downdrafts. Beyond an optimal shear amplitude, squall lines tend to orient themselves at an angle with respect to the low‐level ...

Propagation of tropical squall line-induced storm coastal inundation episodes in Java-Bali, Indonesia [PDF]
Heliyon, 2023 The short-lived tropical squall lines could trigger weather-related hazards to the northern part of the Indonesia Maritime Continent (IMC), such as Sumatra and Kalimantan.

An improvement of wind gust estimate (WGE) method for squall lines
Geomatics, Natural Hazards & Risk, 2022 Severe wind gusts produced by squall lines are difficult to monitor and forecast. This paper assessed and improved the physics-based Brasseur WGE (wind gust estimate) method for diagnosing wind gust of squall lines by coupling the WGE methods with the ...

AGU Advances, 2022 Mesoscale convective systems (MCS) contribute about half of the world's precipitation and create flash flooding as well as other extreme weather events. Despite steady progress in research of these systems in the last several decades, better theoretical ...

Journal of Advances in Modeling Earth Systems, 2023 Water isotopes are tracers of convective processes and are often used as proxies for past precipitation. These applications require a better understanding of the impact of convective processes on the isotopic composition of water vapor and precipitation.

Divergent convective outflow in large-eddy simulations [PDF]
Atmospheric Chemistry and Physics, 2023 Upper-tropospheric outflow is analysed in cloud-resolving large-eddy simulations. Thereby, the role of convective organization, latent heating, and other factors in upper-tropospheric divergent-outflow variability from deep convection is diagnosed using ...
