Western North Pacific GFS Computer model

Note: GFS model means "Global Forecast System". This mathematical model is run four times a day and produces forecasts up to 16 days in advance, but with decreasing spatial and temporal resolution over time. 

It is widely accepted that beyond 7 days the forecast is very general and not very accurate, and most nongovernmental agencies rarely use any of the model's results beyond 10 days.

Western North Pacific NAVGEM model

Note: NOGAPS model means "Navy Operational Global Atmospheric Prediction System Model" which is a bit similar to the GFS model, but is less accurate.

HKO's cloud, and rain simulation in the next 3 days model

This model is an accurate model made by the Hong kong observatory using super computers to model out the next 3 day's of simulated large-scale cloud structure and rain. It is most accurate (70%) at modeling out the potential structure of weather systems like typhoons, but only 60% accuate at modeling where a typhoon would go.

Western North Pacific Vorticity & Streamline model                              

Note: This model is produced by the HKO, and is very accurate, which models out the next 3 days (72hours) of streamline, and vorticity at 1.5km above sea level. Model simulates at an altitude of 1500m (1.5km) above sea level.
