March 2015 Geomagnetic storm with SD-WACCM-X with AMIE electric potential
Abstract
It is expected that very extreme space weather events such as geomagnetic storms will affect thermosphere. However, there are still open questions to address:
• How does the thermosphere respond on a global scale to extreme solar wind forcing during geomagnetic storms?
• To what extent does the global expansion of the high-latitude electric field to lower-latitudes affect the thermosphere?
• Do the thermospheric parameters respond linearly to the associated increase in electric field?
Here we use a specified-dynamics version of the Whole Atmosphere Community Climate Model with thermosphere and ionosphere Extension (WACCM-X) nudged with NASA's ModernEra Retrospective Analysis for Research and Applications (MERRA2) to simulate a geomagnetic storm event that occurred in 17-18 March 2015. The model has horizontal resolution of 1.9° latitude × 2.5° longitude and 145 vertical model levels from surface up to 1.4e-10 hPa (∼500 to ∼700 km, depending on solar activity).

Process overview
| Title | cesm2.2.0 (WACCM-X) |
| Abstract | The model cesm2.2.0 (SD-WACCM-X) is used a hybrid simulation coming from a scientific released version CESM2_1_3 simulation (composet FXSD with resolution f19_f19_mg16) to produce the initialisation files on 5 March 2015. The model is nudged with MERRA2 reanalysis dataset. The simulation is from 0UTC 5 March 2015 to 0UTC 22 March 2015 from surface up to 500-700 km. Here we use CAM6 physics, MA chemistry-MAM4 aerosol scheme. It ran on ARC4 HPCx at University of Leeds. Model output is 1 hour. |
