Piura rainfall and river discharge JISAO data
Piura Perú (5S) rainfall and river discharge
Piura is in the northern coastal desert of Peru. It is a place that is strongly affected by El Niño. The Piura data is provided by Norma Ordinola and Rodolfo Rodriguez of the Universidad de Piura, Perú.

  • The climate of Piura is described in this link (in Spanish) (http://www.met.igp.gob.pe/cpntc/clima/peru/HTML/piura.html)
  • "Piura On Line" (http://www.cipca.org.pe/el_nino/) provides information on the effects of El Niño in Piura (in Spanish).
  • There is an o'kay WWW language translator linked here. "El Nino" becomes "the boy", some of the place names are translated ("Tumbes" the name of a small town near the Ecuador border becomes "you fall down"), etc.
