Low level jet intensification by mineral dust aerosols [PDF]

Annales Geophysicae, 2013
Modification of the intensity of a low level jet (LLJ) and near-surface wind speed by mineral dust is important as it has implications for dust emission and its long-range transport. Using the Weather Research and Forecasting with Chemistry (WRF/Chem)

Brief communication: On the definition of the low-level jet [PDF]

Wind Energy Science, 2023
Low-level jets (LLJs) are examples of non-logarithmic wind speed profiles affecting wind turbine power production, wake recovery, and structural/aerodynamic loading.

Numerical simulation of future low-level jet characteristics

Meteorologische Zeitschrift, 2012
In this paper, results of numerical simulations of low-level jet (LLJ) characteristics are presented. By forcing a boundary layer model with the results of a regional climate model, long time series have been calculated which are analyzed with special ...

A case study of a low-level jet during OPALE [PDF]

Atmospheric Chemistry and Physics, 2015
A case study of a low-level jet (LLJ) during the OPALE (Oxidant Production over Antarctic Land and its Export) summer campaign is presented. It has been observed at Dome C (East Antarctica) and is simulated accurately by the three-dimensional version of ...

Analysis of the Difference between Rainstorm Accompanied by Easterly Low-level Jet in Tarim and Rainstorm without Easterly Low-level Jet in Tarim in Southern Xinjiang

Gaoyuan qixiang, 2023
Most of the regional heavy rain processes in the monsoon region of China are related to the low-level jet.However， in arid and semi-arid regions， the low-level jet stream is not necessarily associated with every rainstorm process.Based on the daily ...

The role and characteristics of low-level jet during a persistent rainstorm in Guangxi

暴雨灾害, 2023
In 2022, Guangxi experienced the strongest Dragon Boat Precipitation since the founding of the People's Republic of China. The persistent rainstorm process from 17 June to 22 June 2022 had large accumulations and overlapping falling areas, leading to ...

Coastal impacts on offshore wind farms – a review focussing on the German Bight area

Meteorologische Zeitschrift, 2022
The atmospheric boundary layer experiences multiple changes in coastal regions, especially with wind directions from land towards the sea, where the wind speed usually increases due to the smaller roughness of the ocean surface.

Analysis of quasi-stationary MCS causing extreme torrential rain event under complex mountains in Southwest Hubei

暴雨灾害, 2022
An extreme torrential rain event occurred in the Jianshi Canyon in the mountainous area of Southwest Hubei on 26 July 2020, which was mainly caused by quasi-stationary mesoscale convection system (MCS).
