Fig. 1: Pressure-temporal evolution of anomalies in the zonal-mean zonal wind, temperature, and geopotential height. WRF-Chem model domain and the thickness of each vertical layer in the simulation.

Fig. 1

Pressure–temporal evolution of (a) the zonal-mean zonal wind anomalies at 60° N (contour; unit: m/s) and temperature anomalies in the polar cap (area averaged over 60°–90° N) (shading; unit: °C), and (b) geopotential height anomalies in the polar cap (shading and contour; unit: gpm) during the period from 1 December 2020 to 28 February 2021. The gray solid line in a and b represents the division of the different stages of the SSW event. c WRF-Chem model domain, orography (shading; unit: m). Black solid dots are stations used to validate the model performance on meteorology and chemistry. The red solid line represents the cross-border line for analysis in the following. d The thickness of each vertical layer in the simulations (54 layers in total).
