Use of ALADIN atthe Weather Forecasting

Centre

• Short range forecast (D, D+1, D+2) General and regional forecasts

Special forecasts FOREST FIRES

• special regional forecasts• wind field• tendency of the FWI

Fire Weather Index (FWI) tendency

ALADIN – Derivated Products


Values available in each point of a regular grid in latitude and longitude

Tend 24 = FWI (H+24) – FWI (H+00) FWI tendency between D and D+1

Tend48 = FWI (H+48) – FWI (H+24) FWI tendency between D+1 e D+2

The graphic presentation of these values is done automatically, in order to obtain two charts, with those tendencies (DIF24 e DIF48) of the fire weather index FWI, daily.
