Analysis of the first gigantic jet recorded over continental North America [PDF]

open access: yes, 2007
[1] Two low-light cameras near Marfa, Texas, recorded a gigantic jet over northern Mexico on 13 May 2005 at approximately 0423:50 UTC. Assuming that the farthest of two candidate storm systems was its source, the bright lower channel ended in a fork at ...

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Effect of wind turbine generator model and siting on wind power changes out of large WECS arrays [PDF]

open access: yes, 1981
Methods of reducing the WECS generation change through selection of the wind turbine model for each site, selection of an appropriate siting configuration, and wind array controls are discussed. An analysis of wind generation change from an echelon and a

Thunderstorm Classification Functions Based on Instability Indices and GNSS IWV for the Sofia Plain

open access: yesRemote Sensing, 2019
Bulgaria is a country with a high frequency of hail and thunderstorms from May to September. For the May–September 2010–2015 period, statistical regression analysis was applied to identify predictors/classification functions that contribute ...

Probability forecasts – Part 1: ensembles and probabilistic forecasts

open access: yesWeather, EarlyView.
Ensemble weather forecasts have been in use for many years to help forecasters understand uncertainty in weather predictions but are now becoming core to some operational Numerical Weather Prediction (NWP) systems. Ensembles offer greater predictive skill and information content than deterministic forecasts but are more complex to interpret and ...

Integrated Schumann Resonance Intensity as an Indicator of the Global Thunderstorm Activity

open access: yesGeosciences, 2023
This paper addresses the accuracy of estimates for the contemporary level of global thunderstorm activity found from the synchronous records of integrated Schumann resonance (SR) intensity at two high-latitude observatories in the Northern and Southern ...

Combination of mesoscale and synoptic mechanisms for triggering an isolated thunderstorm: Observational case study of CSIP IOP 1 [PDF]

open access: yes, 2007
Copyright @ 2007 AMSAn isolated thunderstorm formed in the southern United Kingdom on 15 June 2005 and moved through the area where a large number of observational instruments were deployed as part of the Convective Storm Initiation Project.

Record‐breaking May heat in the UK: contrasting the extreme temperatures of 2024 and 1944 using climate attribution

open access: yesWeather, EarlyView.
This study quantifies the likelihood of May temperature extremes in present, natural (climatology based on pre‐industrial forcings) and future climates. The attribution applies in the context of a May heatwave comparable to the record‐breaking 1944 event and the persistent record‐breaking monthly‐mean temperature from 2024.
