Identification of Precipitation Types by Cluster Analysis Method Case Study: Zahedan. Iran

In this paper daily Precipitation Dataʹs from 1.1.1966 to 3 1.12.2005 examined foridentifi cation precipitation types. First, days of precipitation extracted. Then seven precipitationand four temporal param eters was defin ed for them and finally, matri x of 616 * II for 90 Jprecip itation days were created. A hierarchical cluster analysis by Ward method applied on thismatr ix and five di fferent precipitation types were identifi ed. According to this classification,Zahedan precipitation types are: I-medium, severe and frequent occurrence precip itation type 2Verylow, very short term, more frequent occurrence and very quiet type 3-Low, long term andquiet type 4-High, low occurrence and long durab ility type 5-Very high, low durab ility and verysevere type. These five types, particul arly displayed the Zahedan region precipitationcharacteristics
