Inversion of a Thunderstorm Cloud Charging Model Based on a 3D Atmospheric Electric Field

Applied Sciences, 2018
The measurement of the atmospheric electric field is of great significance for the study of thunderstorm cloud charge models. Traditional electric field meters can only measure the vertical component of the atmospheric electric field, and thus it is ...

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part I: Methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the methods of the areal precipitation nowcasting system NowPrecip version 2. In this version a new methodology is introduced, which, although it shares philosophy and techniques with the original methodology of NowPrecip version 1, can be considered as distinct from that.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

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

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

Geosciences, 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 ...

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

Weather, 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.

The Impact of Environmental Pollution and Climate Change on Allergic Rhinitis and Lung Diseases

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Environmental pollution and climate change seriously affect human health, leading to the onset and exacerbation of chronic respiratory diseases, such as allergic rhinitis and lung diseases. Over the past several decades, increasing air pollution and environmental exposure owing to global urbanization, industrialization, and rapid economic ...

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

Wildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

High Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.
