Magnetic field strength and the LOS velocity ranges in each phase and height.
| Vortex drain phase | Upward-flow phase | Relaxation phase | ||||
|---|---|---|---|---|---|---|
| |B| [kG] | |vLOS| [km s−1] | |B| [kG] | |vLOS| [km s−1] | |B| [kG] | |vLOS| [km s−1] | |
| Photosphere | 0.7–1.2 | ∼1 | 1.0–1.6 | 2–3 | 0.5–1.0 | ∼1 |
| Low & middle chromosphere | ∼0.2 ( * ) | 5–10 | ∼0.25 ( * ) | 10–12 | ∼0.17 ( * ) | 0–3 |
| Upper chromosphere | – | 12–15 | – | 5–40 | – | 0–3 |
Notes. ( * )Estimation using the weak-field approximation. The vortex drain phase and the relaxation phase are dominated by downflows in contrast to the upward-flow phase.
