The predictors used in the rapid intensification (RI) index.
Predictor
|
| Previous 12 h intensity change
|
| 24 h average sea-surface temperature
|
| 24 h average maximum potential intensity -
initial(t = 0 hours) storm intensity
|

from 200 to 800 km radius
|
| 24 h average 850 to 700 mb relative humidity
from 200 to 800 km radius
|
| Standard Deviation of GOES infrared temperatures
from 100 to 300 km radius at t = 0 hours
|
| Percent area covered by GOES
infrared temperatures < -30° C
from 50 to 200 km radius at t = 0 hours
