Climate hazard exposure – score categories based on hot spot analysis results
| Hot spot | Definition | Score | Normalized score |
|---|---|---|---|
| Intensifying (I) | A location that has been a statistically significant hot spot for more than 90% time steps, including the final time step. In addition, the intensity of clustering of high counts in each time step is increasing | 8 | 1.00 |
| Persistent (P) | A location that has been a statistically significant hot spot for more than 90%, with no discernible trend indicating an increase or decrease in the intensity of clustering over time | 7 | 0.875 |
| Diminishing (D) | A location that has been a statistically significant hot spot for more than 90% time steps. In addition, the intensity of clustering of high counts in each time step is decreasing, or the most recent time step is not hot | 6 | 0.75 |
| New (N) | A location that is a statistically significant hot spot only for the last time steps of the time series | 5 | 0.675 |
| Consecutive (C) | A location with a single uninterrupted run of statistically significant hot spot bins in the final time-step intervals. The location has never been a statistically significant hot spot before the final hot spot run and less than 90% of time steps are statistically significant hot spots | 4 | 0.5 |
| Sporadic (S) | A location that is an on-again then off-again hot spot. Less than 90% time steps have been statistically significant hot spots | 3 | 0.375 |
| Oscillating (Os) | A statistically significant hot spot for the final time-step that has a history of also being a statistically significant cold spot during a prior time step. Less than 90% of the time-step intervals have been statistically significant hot spots | 2 | 0.25 |
| Historical(H) | The most recent time period is not hot, but at least 90% of the time step intervals have been statistically significant | 1 | 0.125 |
| Others (Ot) | All cold spots and other nonsignificant hot-spot categories | 0 | 0.00 |
