JWST images of dynamic infrared aurora and a new look at auroral precipitation

Planetary magnetospheres provide natural laboratories for the study of space plasmas, and Jupiter’s magnetosphere in particular acts as a bridge between those phenomena we can study in detail at Earth, and those beyond the solar system that we can only glimpse through telescopes. Jupiter’s auroras have been studied for many years with increasing sensitivity and resolution, but the James Webb Space Telescope offers a revolutionary perspective of these spectacular emissions.

Abstract: Convective Mass Flux (CMF) – the vertical transport of air and water by deep convective storms – drives the large-scale circulation, upper tropospheric moistening, high cloud-raditiave feedbacks, surface precipitation rates, and extreme weather. Despite the fundamental role played by CMF, our understanding of the processes controlling CMF is rudimentary, and the representation of CMF remains a major source of error in our numerical models across the scales.

The thermosphere and the dynamic processes driving the thermospheric responses to major geomagnetic storms

When

Abstract: The thermosphere is an atmospheric region from ~100 km to ~1000 km produced by the atmospheric absorption of solar UV and EUV radiation. It is the region where atmospheric species is not well mixed but diffuses with its own scale height. The thermosphere is an open system changing greatly due to the energy and momentum deposition from the magnetosphere above and the waves from the lower atmosphere.
