Circulation Characteristics and Conceptual Model of Rainstorm Processes in the Eastern Foot of the Helan Mountain

open access: yesGaoyuan qixiang, 2022
In this study, the rainstorm processes are classified into ordinary rainstorm (50~100 mm), heavy rainstorm (100~200 mm) and extraordinary rainstorm (more than 200 mm) according to the accumulated rainfall of the rainstorm process.Then, based on 23 ...

Low-Level Jet Winds at Green River, Utah [PDF]

open access: yesJournal of Applied Meteorology, 1966
Abstract : Wind data at Green River, Utah occasionally show a significant maximum in the speed profile below 5000 feet above the ground. The maximum sometimes occurs under near-adiabatic lapse rate conditions. The development is a nocturnal phenomenon but may persist until near midmorning.

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations

open access: yesWind Energy
Low‐level jets (LLJs) describe conditions in which the wind speed reaches a local maximum with respect to altitude near the surface; they have been observed intermittently in the US mid‐Atlantic offshore environment. LLJs pose unique operating conditions

Role of west Asian surface pressure in summer monsoon onset over central India

open access: yesEnvironmental Research Letters, 2017
Using rain-gauge measurements and reanalysis data sets for 1948–2015, we propose a mechanism that controls the interannual variation of summer monsoon onset over central India.

A Study on the Structural and Formation of the Low-Level Jet Stream over the Northern Persian Gulf (Case study on sinking the Behbahan cargo vessel)

open access: yesInternational Journal of Coastal and Offshore Engineering, 2020
A strong low level jet (LLJ) in the northern region of the Persian Gulf (PG) observed on 5th Jun 2020 that sank the Behbahan cargo vessel. In this article, we have used the WRF-V3 model and reanalysis ERA5 data to study the vertical structure, diurnal ...

Low Level Jets over the Southern North Sea

open access: yesMeteorologische Zeitschrift, 2019
An extensive analysis of Low Level Jets (LLJs) over the Southern North Sea is presented. The study is based on observational data from a wind LiDAR and a passive microwave radiometer, operated from May 2015 to October 2016 on the FINO1 platform, as well as on mesoscale simulations by WRF-ARW. Besides evaluations on LLJ occurrence, intensity, direction,

Mesoscale Convective Systems over Ecuador: Climatology, Trends and Teleconnections

open access: yesAtmosphere
Research on Mesoscale Convective Systems (MCSs) in Ecuador has focused on regional studies. However, it lacks a thorough and general examination of their relationship with the nation’s diverse orography and large-scale phenomena.
