This paper presents a new blending approach: Using meso-scale Numerical Weather Prediction (NWP) products as
environment field, coordinating with weather radar information, blending radar data and NWP model products together,
and finally being applied to short-range forecast and nowcasting. Considering the fact that the weight of radar
extrapolation and NWP model products should be adjusted because they will change with time, three solutions are
offered to calculate NWP weight to blend radar extrapolation and NWP model products in a certain area. At last, RMSF
method is used to verify and examine the example. After qualitative comparison with figures, the results showed:
blending with equal weights and blending with sin2(at+b) as NWP weight improved radar extrapolation and NWP results.
A new effective way has been discussed preliminarily. Hoping it is of reference value to short-range forecast and
nowcasting in further research.
