Abstract:
... Positive Narrow Bipolar Events (+NBEs) in Mississippi thunderstorms were studied using fast antennas (FA, bandwidth 16 Hz - 2.6 MHz) and VHF antennas (Log-RF, bandwidth 186–192 MHz). The waveform characteristics of 201 positive NBEs were determined using both sensors. The +NBEs were classified in two ways: by FA waveform into Types A-D and by +NBE occurrence relative to other lightning events into ...

Abstract:
... Better understanding of the global wave climate is required to inform wave energy device design and large-scale deployment. Spatial variability in the global wave climate is analysed here to provide a range of characteristic design wave climates. K-means clustering was used to split the global wave resource into 6 classes in a device agnostic, data-driven method using data from the ECMWF ERA5 rean ...

Therefore, the challenge is to diagnose cloud-to-ground (CG) lightning at 1 km spatial resolution and, subsequently, preferred regions where Forest Fire Events (FFE) could be naturally ignited. The afternoon of 17th June 2017 has been considered for the study, s ...

Abstract:
... Laboratory cloud chamber experiments have revealed the significance of cloud supersaturation on field-independent graupel-ice crystal charging associated with thunderstorm electrification. At rime accretion rates below approximately 1 g m⁻² s⁻¹, altering supersaturation can reverse the polarity of graupel charging when other conditions are maintained. Explanations are given to reconcile variation ...

Abstract:
... Sprites are transient luminous events (TLEs) that occur at mesospheric altitudes between 50 and 90 km. They last up to several milliseconds, and are caused mostly by positive lightning discharges from the thunderstorm cells below. Infrasound from sprites was first observed in detail a decade ago by a team from the French Atomic Energy Commission (CEA), as part of a renewed international interest i ...

In this paper we deal with the meteorological aspects, which need to be adequately understood in order to understand the occurrence and development of floods. This holds the more as different meteorological environments and accompanying mechanisms can result in different types of heavy precipitation and so in different flood r ...

Abstract:
... Recent studies of thunderstorm-related enhancements of fluxes of energetic radiation and particles at ground level suggest that removal of mid-level negative charge from the cloud by negative cloud-to-ground (-CG) lightning flashes or normal intracloud (IC) flashes serves to abruptly terminate those enhancements. However, it was not clear if the electron-accelerating electric field responsible for ...

Due to the tiny size of dust particles and the low atmospheric pressure, the Martian aeolian activity between Martian dust particles and Martian airflow should be considered as a rarefied two-phase flow.
