First, you’ll notice the GFS model precipitation (shaded) field (fieldin this context means gridded dataset, or a dataset for which there is a value at many different points on a grid) is much more pixelated than the ECMWF precipitation field. This is because the GFS is run at a lower...

GFS 是美国政府在国家海洋和⼤⽓管理局 (NOAA) 及其附属机构的领导下运⾏的全球模型。GFS 模型由美国纳税⼈资助，这意味着任何想要它的⼈都可以免费获得它的预测输出。如果您想从 GFS 模型中获得新鲜的原始输出数据，您可以。虽然原始数据是免费提供的，但使这些数据对最终⽤户有⽤需要⼤量的后处理，...

In this flood event, many locations in western Tennessee and southern Kentucky received 8-10 inches of rainfall and the loss of life (24 deaths) is unprecedented in the history of Tennessee flood events. Precipitation statistics are also used to verify the model runs. The results show that ...

Note (GJF): Precipitation LWE thicknesses are multiplied by the frain factor, and are thus on the dynamics time step, but the conversion as written ! (with dtp in the denominator) assumes the rate is calculated on the physics time step. This only works as expected when d...
These analyses project the GFS precipitation forecast errors onto both time and frequency subspaces. In this way, one can identify on what time-scale (frequency) of forecast errors occur at what time of the year (season, month, and day). In addition, Hurst parameters are computed for these ...
