Investigation and quality assessment of the Past Weather Code from the Integrated Surface Database [PDF]

, 2014
Quantitative SYNOP Code weather variables such as rainfall amount, although of high societal and environmental importance, are frequently subject to recording errors and inhomogeneities resulting in uncertain conclusions.

Charge Structure and Lightning Discharge in a Thunderstorm Over the Central Tibetan Plateau

Geophysical Research Letters
The evolution of charge structure involved in lightning discharge of a thunderstorm over the central Tibetan Plateau is investigated for the first time, based on the data from very high frequency interferometer, radar and sounding.

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part II: Verification

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the verification of the NowPrecip precipitation nowcasting systems (version 1 and version 2). Using 3.5 years of data over the period 2020–2023, their performance is compared with PySTEPS and the ICON numerical weather prediction ensemble by computing deterministic and probabilistic metrics.

Investigation of thunderstorm characteristics with severe lightning events over NE region of India [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The north eastern region (NER) of India is among the hotspot regions for thunderstorm events leading to substantial loss of lives and properties every year. A reliable thunderstorm early warning system can prevent these losses. As these events are highly

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

, 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

High-Altitude Discharges and Whistlers of Volcanic Thunderstorms

Atmosphere
The results of the observations of atmospherics and whistlers initiated by high-altitude electrical discharges that occurred during the eruption of the Kamchatka volcanoes (Bezymianny and Shiveluch (Russia)) on 7 and 10 April 2023 are presented. Recording of atmospherics and associated whistlers was carried out by a VLF (very low frequencies) radio ...

A Pilot Forecasting System for Epidemic Thunderstorm Asthma in Southeastern Australia

Bulletin of The American Meteorological Society - (BAMS), 2020
In November 2016, an unprecedented epidemic thunderstorm asthma event in Victoria, Australia, resulted in many thousands of people developing breathing difficulties in a very short period of time, including 10 deaths, and created extreme demand across ...

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Nighttime observations of thunderstorm electrical activity from a high altitude airplane [PDF]

Journal of Geophysical Research: Atmospheres, 1985
Two sets of observations from a NASA U‐2 airplane looking down on the tops of nocturnal thunderstorms are reported. Photographs show both diffuse illumination in the cloud and unobscured segments of lightning channels a kilometer or longer in clear air around and above the cloud. Multiple images of lightning channels indicate multiple discharges in the

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

International 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
