Abstract: Intensively observed data are used to study possible relationships between winds and rainfall patterns, their evolution, caused by Typhoon 9015 that landed in and travelled across the Zhejiang Province, and mesoscale features surrounding the storm andtopographic effect. It is shown that in consistency with the intensity of winds and rains there is bias in powsitions of pressure and winds centres after the landing. In addition to it, the rainfall is increased suddenly in the eye due to enhanced inflow; the rain-bands are distributed lide belts of 40-601m in width at intervals of 30-100 km and moving trqajectory of major rain clusters mostly rotates clockwisely in relation to the typhoon center; areas of intense winds or rains tend to be at mearby mesoLows (inside inversed throughs), meso-vortex or converging lines (associated with topographic effect).
