Radar data shows graupel and increased turbulence near small-scale intermittent lightning discharges at the top of intense thunderstorms

R. Van Loon, Jelle Assink, O. Schölten, B. M. Hare et autres

Sparkles are the intermittent, small-scale lightning discharges that occur near the top of intense thunderstorms. To increase the understanding of mechanisms that lead to sparkles, we compare high resolution lightning data from the LOw Frequency ARray (LOFAR) to data from a meteorological …

Atmospheric boundary-layer gravity wave observations in the Netherlands

Steven Knoop, Jelle Assink

Over last few years we have observed tens of atmospheric gravity wave (GW) events on our operational network and research instruments in The Netherlands, including the North Sea. These events are ducted GWs that are trapped in the stable boundary layer and …

High‐Resolution Observations of a Mesoscale Gravity Wave Event in the Nocturnal Boundary‐Layer Over the Netherlands and Belgium

Steven Knoop, Jelle Assink, Hidde Leijnse, Sander Tijm et autres

Abstract We present observations of a gravity wave (GW) event over the Netherlands and Belgium in the night and early morning of 30 June 2022. This event was captured by instruments that are part of the meteorological observational network of The Netherlands …

Doppler lidar gravity wave observations within North Sea wind farms

Steven Knoop, Jelle Assink, Mando de Jong

Abstract We present observations of atmospheric gravity waves (AGW) on the Dutch North Sea, using short-range wind lidars that are deployed within offshore wind farms for operational wind measurements. This weather phenomenon can lead to high-amplitude oscillations in the wind speed and …

The details of the 2021 Nyiragongo eruption using infrasound

Julien Barrière, Adrien Oth, Jelle Assink, Nicols d'Oreye et autres

Eruptions at continental basaltic volcanoes can take and combine various forms, including lava lakes, lava flows and fountaining, explosions or structural collapses. Recording seismicity is widely recognized as essential for tracking magma movements at depth but must be complemented with other observations …

Evidence for virtual source-receiver refractions in cross correlations of infrasonic ambient noise

Läslo Evers, Jelle Assink, Julius T. Fricke

Seasonal variability in source activity and atmospheric temperature were retrieved from 11 years of infrasonic ambient noise. Variable lag times between an array (IMS array I53US) and single microbarometer (POKR, AK) were obtained from envelopes of cross-correlation functions. Beamforming and one-bit normalization …

Seismoacoustic analysis of a Falcon-9 rocket stage reentry on 19 February 2025

Patrick Hupe, Christoph Pilger, Jelle Assink, Simon Schneider et autres

Since more than sixty years, rockets have transported tens of thousands of satellites to space. More and more rocket stages and other space debris are returning to Earth, sometimes intentionally, sometimes unexpected. Such descending objects move supersonically through the atmosphere, disintegrate, and …

Atmospheric boundary-layer gravity waves in the Netherlands: Doppler lidar observations at Cabauw atmospheric research station and North Sea wind farms

Steven Knoop, Jelle Assink

Over last few years we have collected tens of atmospheric gravity wave (GW) events, using a long-range scanning Doppler lidar at Cabauw atmospheric research station in the Netherlands, and our North Sea wind lidar network, in which short-range wind lidars are deployed …

Infrasound reveals detailed eruptive processes at Nyiragongo volcano and enhances monitoring capabilities during unrest periods

Julien Barrière, Adrien Oth, Jelle Assink, N. d’Oreye et autres

Eruptions at continental basaltic volcanoes can take and combine various forms, including lava lakes, lava flows and fountaining, explosions or structural collapses. Aside from a few well-instrumented cases worldwide, accurately reconstructing eruptive scenarios is hampered by the lack of detailed visual observations. …
