2009

 The State of São Paulo is situated in the south-eastern region of Brazil and is characterized by summer rain and relatively dry winter months. However, severe storm events can occur any time of the year, but during summer they have a more tropical character, while from about mid-April to September they are usually associated with baroclinic synoptic situations and cold fronts advancing from southern Brazil in a north-easterly direction into the western and central State of São Paulo. The Meteorological Research Institute (IPMet) of UNESP operates two S-band Doppler radars, located at Bauru (Lat: 22°21.5’ S, Lon: 49°1.7’ W, 624 m amsl) and Presidente Prudente (Lat: 22°10.5’ S, Lon: 51°22.5’W, 420 m amsl), respectively (Figure 1). The main characteristics of both radars are: 2° beam width, 450 km range for surveillance mode and 240 km in volume scan mode, with 11 (15) elevations from 0.3° to 35°, 1 km (250 m) radial and 1° azimuthal resolution, and a temporal resolution of 15 minutes or less, recording and archiving reflectivity, radial velocity and spectral width (numbers in brackets are applicable from 2007)
