HAZARD: Drought

PLACEApalachicola–Chattahoochee–Flint basinFixed for the demo. The thin slice takes the caller's own Place; this stored basin is the one we hold.

INDEX

SPEI is stored with Pearson Type III or log-logistic. Selecting SPEI adds Thornthwaite PET. Selecting SPI removes PET. The other settings do not change.

DISTRIBUTION

PET METHOD

Applies to SPEI only. SPI has no PET step.

CALIBRATION PERIOD

ACCUMULATION SCALE

Revision

REPORTING RANGE

A view only. It never changes the calibration or the fit.

Three questions the lab is built for

How much does the baseline matter?

Replay a historical event against different reference periods and see which conclusions survive.

Do the methods agree?

Compare one index across distributions, PET methods and calibration periods.

How strong is the evidence behind each choice?

Each member shows the weakest link in its own chain of scientific evidence.
