Review of the accomplishments of mid-latitude Super Dual Auroral Radar Network (SuperDARN) HF radars [PDF]

Progress in Earth and Planetary Science, 2019
The Super Dual Auroral Radar Network (SuperDARN) is a network of high-frequency (HF) radars located in the high- and mid-latitude regions of both hemispheres that is operated under international cooperation.

The Feature of Ionospheric Mid-Latitude Trough during Geomagnetic Storms Derived from GPS Total Electron Content (TEC) Data

Remote Sensing, 2022
This study aims to investigate the features of the ionospheric mid-latitude trough over North America by using the MIT total electron content data obtained during three geomagnetic storms that occurred in August 2018, September 2017, and March 2015.

Tandem Observations of Nighttime Mid‐Latitude Topside Ionospheric Perturbations

Space Weather, 2023
Nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) have been generally observed by ground‐based instruments. However, they provide 2‐dimensional images over only a limited field of view and are not distributed globally.

Westerly jet waviness modulates mid-latitude hydroclimate variability [PDF]

Nature Communications
The mid-latitude ecological environment is highly vulnerable, and increasing hydroclimate variability poses a significant threat to it. However, the mechanisms driving this variability remain unclear due to short observational records and climate model ...

Spatially Heterogeneous Effects of Atmospheric Circulation on Greenland Ice Sheet Melting

Atmosphere, 2023
The melting of the Greenland ice sheet (GrIS) in summer has rapidly and significantly increased in recent decades, especially for the northern GrIS. Circulation related to GrIS melting is important for understanding the contribution of the GrIS to the ...

A regional classification of time spectral amplitudes in total electron content: Southeastern United States during solar cycle 24

Frontiers in Astronomy and Space Sciences, 2022
To investigate the meso-scale structure (100 s of km) of the ionosphere at mid-latitudes, the spectral properties in calculated total electron content (TEC) at a cluster of GPS receivers in and around Florida are analyzed. The ionosphere does not respond

Correspondence Among Mid‐Latitude Glacier Equilibrium Line Altitudes, Atmospheric Temperatures, and Westerly Wind Fields

Geophysical Research Letters, 2022
Mountain glaciers are highly sensitive to climate change. However, the extent to which glaciers capture regional to hemisphere‐scale atmospheric processes remains uncertain, hindering paleoclimatic interpretations derived from moraine‐based glacier ...

The westerly winds control the zonal migration of rainy season over the Tibetan Plateau

Communications Earth & Environment, 2023
Precipitation over the Tibetan Plateau is modulated by both the South Asian summer monsoon and the mid-latitude westerly winds. Using observations and numerical simulations, this study highlights the out-of-phase relationships between the mid-latitude ...
