A Statistical Investigation of Mesoscale Precursors of Significant Tornadoes: The Italian Case Study
Atmosphere, 2020 In this study, mesoscale environments associated with 57 significant tornadoes occurring over Italy in the period 2000−2018 are analyzed. The role of the vertical Wind Shear in the lower and middle troposphere, in terms of low-level shear (LLS) and

Low level wind shear over Bomba airport
MAUSAM, 1993 Significant climatological features based on 329 Low Level Wind Shear (LLWS) reports from 1985 to 1989 at Bombay airport are presented, The monsoon season has the highest frequency of occurrence of LLWS mainly due to thunderstorms and strong gusty winds, Other than monsoon season, occurrence of LLWS is related to sea and land breeze and nocturnal ...

Wind Lidar and Radiosonde Measurements of Low-Level Jets in Coastal Areas of the German Bight
Atmosphere, 2022 For wind energy, the knowledge of the available wind resource is essential. Therefore, specific wind phenomena at the altitude range of wind turbines are currently the focus of investigations. One such specific feature is the low-level jet (LLJ).

How Wind Shear Affects Trade‐wind Cumulus Convection
Journal of Advances in Modeling Earth Systems, 2020 Motivated by an observed relationship between marine low cloud cover and surface wind speed, this study investigates how vertical wind shear affects trade‐wind cumulus convection, including shallow cumulus and congestus with tops below the freezing level.

The WRF Model Forecast-Derived Low-Level Wind Shear Climatology over the United States Great Plains
Energies, 2010 For wind resource assessment projects, it is common practice to use a power-law relationship (U(z) ~ zα) and a fixed shear exponent (α = 1=7) to extrapolate the observed wind speed from a low measurement level to high turbine hub-heights. However, recent

Wind shear over the Nice Côte d'Azur airport: case studies [PDF]
Natural Hazards and Earth System Sciences, 2013 The Nice Côte d'Azur international airport is subject to horizontal low-level wind shears. Detecting and predicting these hazards is a major concern for aircraft security.
