Abstract:
With the establishment of radar network in the coastal area of China, r adar measurements are becoming an important monitoring method for approaching ty phoon especially before its landfall. An objective method to retrieve wind via t racing radar echo displacement is described in details and applied to the circul ation and intensity estimation of landing typhoons “Nari" and “Chebi" i n 2001. It is found that real wind distribution features can be captured effectively usin g CAPPI and PPI radar images by quality control with an accuracy equivalent to t he operational analysis.
