Flooding in Brazil, Argentina, and Uruguay

Flooding in Brazil, Argentina, and Uruguay

By early December 2009, a dozen people had been killed and thousands had been evacuated in the wake of flooding in Brazil, Argentina, and Uruguay. This image shows estimated rainfall for the region from November 19–25, 2009. The highest amounts of rain—more than 400 millimeters (16 inches)—appear in dark blue. The lightest amounts—less than 50 millimeters (2 inches)—appear in pale green. Torrential rainfall concentrates close to where the borders of the three countries meet, with an especially intense area of rain just north of the Brazil-Uruguay border.

This analysis is based on data from the Multisatellite Precipitation Analysis, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite.
