Computer Weather Models                  
A list of links to super computer models, modeling, and simulating out next week's weather in precipitation, pressure, and even the development of a tropical cyclone which has not existed yet, but maybe, in the future.

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. This model often models out a future tropical cyclone to form, ranging from 50% to 90% in accuracy.

Western North Pacific COAMPS model

Note: The COAMPS model is a High resolution model, which only goes out to only 2 days into the future.

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, and models out less precipitation, and more cyclonic systems, often modeling them being weak.
It is 40% accurate.

Hong Kong Observatory
These prognostic charts start updating at 03 HKT, 09 HKT, 15 HKT, 21 HKT everyday. 

Hong Kong observatory South China  sea and west pacific region computer models
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.


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.
