GribStream

Central Weather Administration WRF 15 km

Código GribStream: cwawrf15

Descrição

CWA WRF 15 km é uma saída regional da Central Weather Administration de Taiwan baseada no Weather Research and Forecasting model.

O dataset é útil quando o produto precisa de contexto regional no Pacífico ocidental, especialmente onde modelos focados nos Estados Unidos, como HRRR ou RAP, não se aplicam.

No GribStream, cwawrf15 permite consultar campos WRF por coordenada e horário com o mesmo padrão de API usado nos demais modelos.

Combine com GFS, IFS Oper e AIFS quando você precisa comparar orientação regional e global.
