Preliminary Pavala scale
The preliminary Pavala scale is the scale that Kalassak will use to assess the intensity of cyclones in basins without defined cyclone scales. It is based on the Saffir-Simpson hurricane wind speed scale, but the number of categories is adjusted to match the vast majority of Earth-wide cyclone scales. The changes are as follows:
- Tropical storm is split into two categories at 48 kts (based on JMA scale)
- Categories 1 and 2 are merged into one category with no changes to bounds (every other scale has 3 hurricane-force categories)
- Categories 3 and 4 are merged into one category with no changes to bounds (every other scale has 3 hurricane-force categories)
| Classification | Wind speed (kts) |
|---|---|
| Tropical depression | < 34 kts |
| Tropical storm | 34 - 47 kts |
| Severe tropical storm | 48 - 63 kts |
| Tropical cyclone | 64 - 95 kts |
| Intense tropical cyclone | 96 - 136 kts |
| Violent tropical cyclone | ≥ 136 kts |
North and South Uqe
Wind speeds in the North and South Uqe basins are given in kezpíga per úko, rounded to the nearest 10 (in base 12). Conversions to knots are rounded to 5. Measurements are 1-<soleani minute>/144 úko (or approx. 10-minute) averages.
