The classification of TPV category cloud clusters based on the phase on cloudtop.
| Classification criteria | Range of threshold for TBB on cloudtop and corresponding acreage |
| Pure ice-phase type | (1) TBB ≤ 233 K; (2) S ≥ 100000 km2 |
| Ice-water mixed-phase type | (1) 233 K < TBB < 273 K; (2) S ≥ 100000 km2 | (1) TBB ≤ 233 K; (2) S < 100000 km2 |
