Explaining the dynamics of the sub-relativistic electron third belt in the Earth’s radiation belts by using medium Earth orbit satellite observations

Earth and Planetary Physics
The Earth’s electron radiation belts typically exhibit a two-belt structure. However, observations from the Van Allen Probes revealed the existence of a three-belt structure.

Optical Signatures of the Outer Radiation Belt Boundary

Geophysical Research Letters, 2019
We present observations that show structured diffuse aurora (SDA) correlated with electron precipitation directly from the outer boundary of the outer radiation belt.

Processes in auroral oval and outer electron radiation belt

Earth, Planets and Space, 2018
We have analyzed the role of auroral processes in the formation of the outer radiation belt, considering that the main part of the auroral oval maps to the outer part of the ring current, instead of the plasma sheet as is commonly postulated.

Two centuries of Begonia exploration in the Philippines: Progress and challenges associated with a megadiverse genus in the Global South

PLANTS, PEOPLE, PLANET, EarlyView.
Megadiverse genera represent the highest concentration of plant diversity, but these plants are also located primarily in countries in the Global South where huge gaps in botanical knowledge remain. This study summarized two centuries of Begonia collection records in the Philippines to show how historical events coincide with collection and taxonomic ...

Transient distortions of the South Atlantic Anomaly radiation environments driven by electric fields

Nature Communications
Energetic electrons in Earth’s inner radiation belt pose significant hazards to spacecraft systems, with the strongest radiation in low-Earth orbit (LEO) mostly confined to the South Atlantic Anomaly (SAA) region.

Combined Effects of Equatorial Chorus Waves and High‐Latitude Z‐Mode Waves on Saturn's Radiation Belt Electrons

Geophysical Research Letters, 2019
In this paper, we examined the combined effects of equatorial chorus waves and high‐latitude Z‐mode waves on the energy and pitch angle distribution of Saturn's radiation belt electrons.

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

The physical and synoptic‐dynamical differences between warm days, hot days, and heatwaves during summer in Victoria, Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the day, there is composite mean cold advection in the boundary layer on warm days (WDs), hot days (HDs) and heatwaves (HWs). There is weaker surface‐sensible heating on HDs and HWs. A nocturnal jet advects warm air on HDs and HWs. There is a strong and slow‐moving upper‐level anticyclone on HWs.

Hysteretic behavior of a belt tensioner: modeling and experimental investigation [PDF]

, 2005
In this paper we describe the modeling of the hysteretic behavior of belt tensioners. An initial experimental device is composed only of the tensioner by using forcing frequencies, preloads and deflection amplitudes.

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...
