Comparison of precipitation nowcasting by extrapolation and statistical-advection methods
of the year were evaluated. The first model was based on the extrapolation of observed radar reflectivity (COTREC-IPA) and the second one combined the extrapolation with the application of a statistical model (SAMR). The accuracy o...

Quantitative expression of uncertainty in nowcasting heavy convective precipitation in central Europe by extrapolation methods
Methods extrapolating observed radar reflectivity along Lagrangian trajectories are frequently used for nowcasting of precipitation. The forecast errors of these methods these two errors and then quantify predictability and uncertai...

Limits of precipitation nowcasting by extrapolation of radar reflectivity for warm season in Central Europe
shows that that the mean DCT for the extrapolation forecast is 45.4 min, whereas the DCT for the persistent forecast is 13.4 min shorter. However, the DCT may increaseCurrent precipitation nowcasting systems primarily use ...
