| Zusammenfassung |
| Although methods of using multiple Doppler radars to study wind fields have
long been proposed, and many research studies have been made, very few
operational radar operators adopt methods which require the use of specific
scanning strategies to allow the extraction of wind information. Here we
report a collaborative study on dual-Doppler radars based on two Doppler
radars in the Po valley, Italy. Unusually, the radars are only about 90 km
apart, though operated by the same authority. The wind field syntheses are
carried out on a 30 km by 30 km region where the two radars have overlapping
scan coverage. An iterative method based on the linear wind model and the
equation of mass continuity is used to construct the wind fields. The
methodology has been validated by two different methods. The first method is to
reconstruct the radial wind observed by each radar, and the second method is
calculating and comparing the along-track component with that derived from the
observations. Both two comparisons show good agreement with the original
data. |
