Episode #122 - What's the Weather in Space? w/ Jose Arnal

·1 hr 42 min·5 clips
Jose details how scientists can relax the assumptions of ideal MHD to create models like resistive MHD or incorporate viscosity, moving towards Navier-Stokes equations.
Host Ray interviews Jose Arnal, a PhD candidate in space physics, about the science of space weather. They explore what coronal mass ejections are, how they cause auroras and threaten satellites and power grids, and the complex computational models used to predict them. The conversation delves into magnetohydrodynamics (MHD) and the role of data assimilation in improving forecasts.

As heard by us

A dense but clear tour of space physics that shows why ideal MHD still matters.

Ray and Jose Arnal spend most of this episode in the deep end of space physics, where ideal MHD meets the uglier reality of space plasmas. The best stretches are the ones that slow down and nail the basics, especially what mean free path means and why a model that should not…
