Numerical Weather Forecast Charts
Hong Kong Observatory (HKO) A collection of forecast charts at surface level, 850, 700, 500 and 200 hPa of up to 72 hours. Uses the Non-Hydrostatic Model (NHM)
European Centre for Medium-Range Weather Forecasts (ECMWF) Forecasts mean sea level pressure, 850 hPa wind speed and 500 hPa geopotential heights. Ranges from t+72 hours to t+240 hours with an increment of 24 hours. Past forecast base times are also available.
Korea Meteorological Administration (KMA) Forecasts of up to 72 hours are available. Provides weather details of different layers of atmosphere.
Central Weather Bureau (CWB) Provides different models with information about various layers of atmosphere.

Fleet Numerical Meteorology and Oceanography Center (FNMOC):

- NAVGEM
- GFS

Models developed in the United States. Both models provide weather details of different layers of atmosphere, but NAVGEM provides more choices than GFS. As of December 2015, both models provide predictions of up to 180 hours ahead. "NAVGEM"and "GFS" stand for "Navy Global Environmental Model" and "National Weather Service Global Forecast System" respectively. The NAVGEM model replaced the older NOGAPS in 2013.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) A collection of forecast charts for different parameters of up to 120 hours.
Tropical Tidbits A collection of forecast charts based on different models. Link defaults to ECMWF model, but others can be selected through the "Global" tab on the page.
