Table 7
Three-stage climate zoning of airport overlay in hot and humid area.
| Level 1 zoning | Ultrahigh temperature area | High temperature area |
| Hottest monthly mean temperature (°C) | ≥40 | <40 | Region of origin | Hot and humid northern tropical desert climate area | Tropical rainforest climate zone and tropical grassland climate zone |
| Level 2 zoning | Rainy area | Less rainfall area |
| average annual rainfall (mm) | ≥1000 | <1000 | Region of origin | Tropical rainforest climate area near the equator | Other regions except tropical rainforest climate zone |
| Level 3 zoning | Regions with large temperature difference | Regions with small temperature difference |
| Average temperature difference between day and night (°C) | ≥15 | <15 | Region of origin | Hot and humid northern tropical desert areas | Areas other than tropical desert climatic areas |
