FNMOC的數值預報網站
其中最主要的NOGAPS(NGP)模式已在今年9月作出程式更新
提升其縱向和橫向解析度(我應該沒有會錯意^^ 原文在下)
Effective 18 Sept 2002, FNMOC commenced operation of NOGAPS at a higher
resolution. The model resolution increased from T159L24 to T239L30, where T
represents the number of spectral waves the model can resolve and L represents
the number of vertical levels. Successful parallel-ops testing took place
during July and August 2002. Testing confirmed the new model resolution provides
a positive impact on the prediction of low level winds, precipitation, and
tropical cyclone tracks in the tropics and some positive impact in the
mid-latitudes. Check the FNMOC homepage at Notice Regarding NOGAPS Model
Improvement for more detailed information on the testing results.
This implementation marks the first step in a phased approach to upgrading our
numerical weather prediction (NWP) capability.
此外FNMOC的另兩個全球數值預報模式的AVN和MRF則更新結合成為GFS Model
並且已在最近幾日在網站上顯示GFS的數值結果
但從11/20起 GFS將一日跑四次數值
並且將預報時間延長到384小時(相當於16天)!!!!
如此一來以後的"雙週天氣預報"將可能實現!!!!
原文如下:
On 24 April 2002 at 00Z the NCEP MRF and AVN forecast outputs were combined and
renamed the Global Forecasting System (GFS). The GFS is run four times per day
and extends to the 384 hour forecast (16 days).
FNMOC receives this data at 1 degree grid resolution for the 0-180 hour
forecast and 2.5 degree resolution from 180-364 hours. FNMOC will make changes
to reflect the new model name NCEP_GFS on 11/20/02. For more information about
changes to the GFS model, visit the following website:

(誰可以解釋一下什麼1 degree grid和2.5是什麼意思?)
