We will present composites of analyses from the NCEP GFS model at the time of TC formation in the NHC best track over several years to attempt to quantify thresholds in the model fields that can be used to identify TC genesis. Ideally, these composites could be expanded to additional global...

NCEP/NCAR再分析项目是美国国家环境预测中心(NCEP,前身为 "NMC")和美国国家大气研究中心(NCAR)的一个联合项目。这项联合工作的目标是利用历史数据产生新的大气分析,以及产生对当前大气状态的分析(气候数据同化系统,CDAS)。NCEP/NCAR Reanalysis 1项目正在使用最先进的分析/预报系统,利用1948年至今的过去数据进行数据同化。

For more detailed description of GEFS-Aerosols, interested readers are referred to L. Zhang et al. (2022). 2.2 Stochastically Perturbed Emission (SPE) Approach In an ensemble-based DA approach, model uncertainty is usually analyzed in terms of ensemble spread and correlations. It is well known...
This paper aims to assess the performances of different model initialization conditions (ICs) and lateral boundary conditions between two global models (GMs), i. e., the European Centre for Medium-Range Weather Forecasts (ECMWF) and National Centers for Environmental Prediction (NCEP), on the accu...
The North Atlantic Hurricane (NAH) wave model has been developed at the National Centers for Environmental Prediction (NCEP) to produce forecasts of hurricane-generated waves during the Atlantic hurricane sea- son. A detailed description of this model and a comparison of its perfor- mance against ...
The prediction capability of dominant daily monsoon modes of Indian summer monsoon in the forecast of the Global Forecast System Version 2 (GFSv2) model is scrutinized. The dominant monsoon modes are procured by performing the multichannel singular spectrum analysis (MSSA) on daily precipitation ...
