By analyzing statistics and dynamics in this text, we can come to such conclusions: (1) The ECMWF medium-term numerical forecast can forecast medium-term activity of subtropical high, and the accuracy rate of forecast cannot have large improvement by transnational corrections.

) during 1986 ~ 2002 in Nanning from the three aspects of synoptic meteorology, single station elements and European Numerical Products.

While the ERA40 project by European Center for Medium-Range Weather Forecasts(ECMWF) provides ozone reanalysis data,in order to use the data more effectively and reasonably,a comparison analysis is done for the ERA40 and Halogen Occultation Experiment(HALOE) data.

According to the principle of forest fire, by usage of meteorological information of 9210 transmission, we have achieved the forecast system of fire weather scale forecast, based on the fire weather factors selected from T106 and HLAFS NWP Product of China meteorological center.

The Application of numerical prediction products to the Severe rain forecasting in xianyang region;

And the paper also gave a synoptic explanation for numerical prediction product.

The influence system and the physical quantities field related this process were analysed with ECMWF and T213 numerical prediction product and routine weather data in this paper.

A new forecast application of numerical forecast products is exemplified by use of artificial neural network(ANN) to daily forecasts of the regional average precipitation of Guangxi in May and June.

There is a problem that instantaneous value of forecasting factors does not match with accumulated precipitation forecast in explaining and application of numerical forecast products.

This article introduced the numerical forecast products of the Japan Meteorological Agency(JMA) and described the path and the naming rules of documents in detail,also it told about how to use these materials in meteorological operation.
