主要将提高分辨率..不过对于公众用户似乎不构成直接影响

ECMWF plans to upgrade the horizontal resolution of its analyses and forecasts.The upgrade will have a horizontal resolution that translates to about 9 km for HRES and the data assimilation (the outer loop of the 4D-Var) and to about 18 km for the ENS up to day 15. The resolution of the ENS extended (day 16 up to day 46) will be about 36 km.
A new cycle of the IFS will be introduced to implement the horizontal resolution upgrade. This cycle is labelled 41r2 and includes a number of enhancements to the model and data assimilation listed herein. The detailed specification of the resolution upgrades included in IFS cycle 41r2 are:
Introduction of a new form of the reduced Gaussian grid, the octahedral grid, for HRES, ENS and ENS Extended;
Horizontal resolution of the HRES increased from TL1279 / N640 to TCO1279 / O1280, where subscript C stands for cubic and O for octahedral;
Horizontal resolution of the ENS increased from TL639 / N320 to TCO639 / O640 for ENS (Days 0 - 15) and from TL319 / N160 to TCO319 / O320  for ENS Extended (Days 16 - 46);
For the medium-range ENS there will no longer be a decrease of resolution at day 10: the ENS Days 11 - 15 will be run at the same TCO639 / O640 resolution as ENS Days 0 - 10;
Increase of the HRES-WAM resolution from 0.25 to 0.125 degrees and the ENS-WAM Days 0 - 15 from  0.5 to 0.25 degrees;
Horizontal resolution of the EDA outer loop is increased from TL399 to TCO639 with its two inner loops increased from TL159 / TL159 to TL191 / TL191, respectively;
Horizontal resolution of the three 4DVar inner loops is increased from TL255 / TL255 / TL255 to TL255 / TL319 / TL399, respectively.
These upgrades
do not include any increase in the vertical resolution;
do not apply to the ECMWF seasonal forecasting system;
do not apply to the standalone wave model (HRES-SAW);
do apply to products from the Boundary Condition Optional Programme.
During the Release Candidate test phase forecast data will be made available close to real time via
product dissemination

那是最美好的时代,那是最糟糕的时代;那是智慧的年头,那是愚昧的年头;那是信仰的时期,那是怀疑的时期;那是光明的季节,那是黑暗的季节;那是希望的春天,那是失望的冬天;我们拥有一切,我们一无所有; 我们全都在直奔天堂,我们全都在直奔相反的方向------简而言之,那时跟现在非常相象,某些最喧嚣的权威坚持要用形容词的最高级来形容它。说它好,是最高级的;说它不好,也是最高级的。

和升级无关。升级是无缝对接
