Quarterly Journal of the Royal Meteorological Society, EarlyView.This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

A new scale‐selective measure of curvature for meteorological fields
Quarterly Journal of the Royal Meteorological Society, EarlyView.We introduce a novel diagnostic called curvature using radial variation (CURV) that quantifies the local cyclonic or anticyclonic curvature of mean‐sea‐level pressure or geopotential height gridded fields over selected scales. A depiction of how CURV values relate to differing cyclonic curvature is shown in the figure.

Object‐based deep learning for probabilistic convective‐core nowcasting from satellite data
Quarterly Journal of the Royal Meteorological Society, EarlyView.Convective cores detected from Meteosat infrared imagery are represented as compact physical objects to generate probabilistic nowcasts up to 6 h ahead. A spatio‐temporal transformer models interactions among evolving core populations and produces gridded probability forecasts across the western Sahel.

Radar-Based Analysis of Convective Storms over Northwestern Italy
Atmosphere, 2011 Thunderstorms may cause large damages to infrastructures and population, therefore the possible identification of the areas with the highest occurrence of these events is especially relevant.

Identification of favorable environments for thunderstorms in reanalysis data
, 2017 The relations between lightning occurrence over Europe from the EUCLID network (2008–2013) and parameters derived from ERA-Interim reanalysis data were studied to increase the understanding of the conditions under which thunderstorms form.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Precipitation growth and decay due to orography was analyzed using the radar network in Great Britain. Storm direction and speed modulate the intensity of precipitation growth or decay. Windward slopes predominantly exhibit precipitation growth, while leeward areas show precipitation decay.

Damaging thunderstorms in Finland in June 2021
Thunderstorms are common in Finland, however, high-impact damaging cases do not occur every summer. On 21–23 June 2021, three damaging thunderstorms, named Ahti, Paula and Aatu, occurred in Finland.

Thunderstorms & Equatorial Sporadic-E [PDF]
, 1972 265-268The passage of thunderstorms over the equatorial station Thumba during night-time is found to enhance the multiple reflections as well as the maximum frequency of radio waves reflected from the Es-region.

U.S. Hail Frequency and the Global Wind Oscillation
Geophysical Research Letters, 2018 Changes in Earth relative atmospheric angular momentum can be described by an index known as the Global Wind Oscillation. This global index accounts for changes in Earth's atmospheric budget of relative angular momentum through interactions of tropical ...
