Analysis on characteristics and causes of a heavy snowstorm event in southern Henan in the beginning of January 2018

open access: yes暴雨灾害, 2019
Based on conventional observation data and NCEP/NCAR 6-hour reanalysis data with 1°×1° resolution, we analyzed the characteristics and causes of a heavy snowstorm event in southern Henan in the beginning of January 2018. The results show that this event,

Wind Shear of Low-Level Jets and Their Influence on Manned and Unmanned Fixed-Wing Aircraft during Landing Approach

open access: yesAtmosphere, 2021
Wind shear at low altitudes represents a potential hazard to landing aircraft. Based on two wind lidar data sets of one year, the occurrence of low-level jets (LLJs), the vertical wind shear and the rotation of the wind direction were analysed. The lidar

EFD-C(13)03/14 Dynamic of Density Profiles in JET During Slow L-H Transition [PDF]

open access: yes, 2013
In tokamaks, the H-mode is characterized by density and temperature pedestals that build up at the L-H transition. During JET 2012 campaign, discharges were carried out with a smooth increase of heating power to compare the L-H transition threshold in ...

EFD-C(13)03/46 Comparisons Between EDGE2D/EIRENE Simulations and D and Low Z Impurity Spectral Emission from JET ITER-like Wall L-mode Plasmas [PDF]

open access: yes, 2013
An understanding of the behaviour of the plasma edge and divertor physics is essential for the design of next-step machines such as ITER, for which JET with its ITER-Like Wall (ILW) of Be in the main chamber and W in the divertor is ideally suited.

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV [PDF]

open access: yes, 2013
The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy ofs√=7 TeV corresponding to an integrated luminosity of 38 pb−1.

EFD-C(13)03/09 Study of the Effect of the Outer-Strike Point Location on the Divertor Neutral Pressure in JET-ILW Using EDGE2D/EIRENE [PDF]

open access: yes, 2013
During the first year of the JET-ILW operation, a substantial effort was devoted to the L-mode domain characterization with the newly installed ITER-Like Wall (ILW), consisting of a W divertor and a Be main chamber.

Analytical description of a nocturnal low‐level jet [PDF]

open access: yesQuarterly Journal of the Royal Meteorological Society, 2010
AbstractAn exact analytical solution of the equations of motion is presented for the Blackadar conceptual model of the nocturnal low‐level jet as an inertial oscillation arising from the sudden release of frictional constraint (near‐cessation of dry‐convective turbulent mixing) near sunset.

EFD-C(13)03/11 Contrasting H-mode Behaviour with Fuelling and Nitrogen Seeding in the All-Carbon and Metallic Versions of JET [PDF]

open access: yes, 2013
An all-metal ITER-Like Wall (JET-ILW), consisting of beryllium in the main chamber and tungsten surfaces in the divertor, has now been installed in JET to pursue low retention of fuel species and to explore the impact on next-step-relevant plasmas.

Synoptic-Scale Forcing and Its Role in a Rare Severe Rainfall Event over the UAE: A Case Study of 15–16 April 2024

open access: yesAtmosphere
An intense rainfall event affected the United Arab Emirates (UAE) between 15 and 16 April 2024. This study investigated the atmospheric conditions responsible for the formation of large convective storms during this period.

Development of an idealised downstream cyclone: Eulerian and Lagrangian perspective on the kinetic energy [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2013
In this idealised modelling study, the development of a downstream cyclone, which closely follows the life-cycle of a Shapiro-Keyser cyclone, is addressed from a quasi-geostrophic kinetic energy perspective.
