Due to a delay of approximately 7 hours in the arrival of ECMWF-IFS forecast product data at the forecast platform, we cannot directly use the latest ECMWF-IFS 0-24 hour forecast results for correction and use in meeting the needs of forecasters. Instead, we use the ECMWF-IFS 12-36 hour forecast results from the previous time step for correction and use, as well as for the forecast results comparison in the following text. For example, when we need to make a 0-24 hour forecast for today's 1200 UTC forecast (corresponding to the forecast from 1200 UTC today to 1200 UTC tomorrow), the ECMWF-IFS data used by both models for comparison is the 12-36 hour forecast (corresponding to the forecast from 1200 UTC today to 1200 UTC tomorrow) from today's 0000 UTC forecast. In the subsequent forecast results comparison, we use the forecast lead time of both models' results as the marker, i.e. 0-24 hours. The data from January 2017 to December 2020 are used as the training and verification sets for model training, with 20% of the data randomly selected as the validation set and the remaining 80% used as the training set

可以帮我把这段话翻译成英文么?由于ECMWF-IFS预报产品数据在到达预报平台时大概滞后7h左右为满足预报员业务应用需求我们并不能直接使用最新起报的ECMWF-IFS 0-24小时预报结果进行订正释用而是利用上一个起报时次的ECMWF-IFS 12-36小时预报结果进行订正释用下文的预报结果对比也是如此。如:当我们需要做今天1200 UTC起报的0-24小时的预报对应的就是今天1200 UTC
