CLIMATOLOGY OF THE LOW LEVEL JET

Monthly Weather Review, 1968
(Uploaded by Plazi for the Bat Literature Project) Geographical and diurnal variations in the frequency of occurrence of strong low level wind maxima arc detcrmined using 2 yr. of wind data from 47 rawinsonde stations in the United States. Maximum frequency of occurrence is found in the Great Plains at approximately 37'N. and 98"W. The vast majority of

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

Atmosphere
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]

Tellus: 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.

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

Environmental 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.

Using the Polar Jet Stream Core Wind Speed to Estimate the Surface Low Pressure System value during winter

Al-Mustansiriyah Journal of Science, 2019
The work studied the relationship between polar jet stream core speed at 300 hPa level and the surface low pressure system on winter seasons during years from 2014 to 2016. Februaries were chosen from winter seasons which the polar jet stream passes with

The Impacts of Atmospheric Moisture Transportation on Warm Sector Torrential Rains over South China

Atmosphere, 2017
Warm Sector Torrential Rains (WSTRs) occurring during the outbreak of the monsoon in May of 2015 in South China were studied using surface automatic weather observational data, sounding, European Centre for Medium-Range Weather Forecasts Reanalysis ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Associations of Sleep and Shift Work With Osteoarthritis Risk

Arthritis Care &Research, EarlyView.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations

Wind 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
