Journal of Aerospace Technology and Management, 2012 A statistical analysis of precipitation at Rio Grande do Sul State was presented in this article. The aim of this work was to identify spatial and temporal patterns of maximum precipitation, which was achieved by fitting a theoretical variogram in ...

Mixed layer depths via Doppler lidar during low-level jet events
EPJ Web of Conferences, 2018 A low-level jet (LLJ) is a prominent wind speed peak in the lower troposphere. Nocturnal LLJs have been shown to transport and mix atmospheric constituents from the residual layer down to the surface, breaching quiescent nocturnal conditions due to high ...

Lidar Studies of Wind Turbulence in the Stable Atmospheric Boundary Layer
Remote Sensing, 2018 The kinetic energy of turbulence, the dissipation rate of turbulent energy, and the integral scale of turbulence in the stable atmospheric boundary layer at the location heights of low-level jets (LLJs) have been measured with a coherent Doppler light ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Noise-silencing technology for upright venting pipe jet noise
Advances in Mechanical Engineering, 2018 When a natural gas transmission and distribution station performs a planned or emergency venting operation, the jet noise produced by the natural gas venting pipe can have an intensity as high as 110 dB, thereby severely affecting the production and ...

Sensitivity of Low-Level Jets to Land-Use and Land-Cover Change over the Continental U.S.
Atmosphere, 2019 Lower-tropospheric wind maxima, known as low-level jets (LLJs), play a vital role in weather and climate around the world. In this study, two 10-year (2006–2015) regional climate simulations using current (2011) and future (2100) land-use/land ...

Multiscale analyses of moisture transport by the central plains lowlevel jet during IHOP
, 2004 During the International H2O Project (IHOP) in the Southern U.S. Central Plains in May and June 2002, aircraft missions on June 3 and June 9 2002 made detailed lidar and dropsonde observations of intense phases of the low-level jet (LLJ) . Combined with

Nocturnal Boundary Layer and Low-level Jet Characteristics under Different Turbulent Regimes [PDF]
, 2015 The intensity, extent, and continuity of turbulence in the nocturnal stable boundary layer (SBL) is governed by many interacting processes and features. Generally, SBLs can be grouped into two broad categories: weakly stable and very stable.
