Pankov Ciencias de la Tierra Solar ocean rains climate solar cycle Precipitation in Brazil for three meteorological stations (Pelotas: 31°45S, 52°21W; Campinas: 22°53S, 47°04W; Fortaleza:3°45S, 38°31W) from 1849 up to 2000 were considered. Periodic analysis of annual rainfall in Pelotas and Fortaleza showsbidecadal periodicity over 100-150 years with variation amplitude of about 90%. High correlation/anticorrelation coefficientswith the 22-year solar magnetic field cycle in Fortaleza are -77%±4% during 18491940 and +80.0±4% during 1952-2000, and inPelotas 60%±13% in 1893-1920 and -84 %±4% during 1929-2000. Correlation with 24-year periodicity is +54%±6% in Fortalezaduring 1849-2000. Short term correlations of Brazilian rainfall level with magnetic sector boundary of interplanetary magneticfield crossing by Earth, with solar flare particle events, and with Forbush decreases in cosmic rays during ~ 50 years of observationswere negative. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843215 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43 |
