Probability forecasts – Part 1: ensembles and probabilistic forecasts

Weather, 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 ...

Sensitivity of a Bowing Mesoscale Convective System to Horizontal Grid Spacing in a Convection-Allowing Ensemble

Atmosphere, 2020
The bow echo, a mesoscale convective system (MCS) responsible for much hail and wind damage across the United States, is associated with poor skill in convection-allowing numerical model forecasts.

Holes in Optical Lightning Flashes: Identifying Poorly Transmissive Clouds in Lightning Imager Data

Earth and Space Science, 2021
Space‐based optical lightning sensors including the lightning imaging sensor (LIS) and geostationary lightning mapper (GLM) are pixelated imagers that detect lightning as transient increases in cloud top illumination. Detection requires optical emissions

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.

Advances towards the development of a cloud-resolving model in South Africa

South African Journal of Science, 2014
Recent advances in supercomputing have made feasible the numerical integration of high-resolution cloud-resolving models (CRMs). CRMs are being used increasingly for high-resolution operational numerical weather prediction and for research purposes.

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 ...

Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

High Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

Coal and fuel burning effects on the atmosphere as mediated by the atmospheric electric field and galactic cosmic rays flux [PDF]

, 2009
: Emissions into the atmosphere of Greenhouse Gases (GHGs) and particulate matter resulting from fossil fuel burning are considered to be the main anthropogenic forcing on the global climate.

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

Allergy, EarlyView.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,

UHF and VHF radar observations of thunderstorms [PDF]

, 1986
A study of thunderstorms was made in the Summer of 1985 with the 430-MHz and 50-MHz radars at the Arecibo Observatory in Puerto Rico. Both radars use the 300-meter dish, which gives a beam width of less than 2 degrees even at these long wavelengths ...
