| Abstract | We present in this work a statistical study of the near-ground air temperatures in different latitudes during periods with decrease of atmospheric ionization induced by Galactic Cosmic Rays (GCR) on the Earths atmosphere. These GCR fluxes reductions are called Forbush Decreases (FD), and they are mainly caused by interplanetary Coronal Mass Ejection (CME) deflection of GCR around Earth´s orbit. This study was perfomed considering the possible influence of the cosmogenic atmospheric ionization on the water vapor condensation patterns (link GCR cloud condensation nuclei) as the main hypothesis to be tested. For that, we have conducted a study to analyze these possible effects on the air surface temperature, using superposed epoch analysis around the ten strongest FD events occurred between 1987 and 2015. GCR data were collected from Oulu neutron monitor (cosmicrays.oulu.fi), and air surface temperature data were obtained from NOAA - National Oceanic Atmospheric Administration / GSOD - Global Surface Summary of the Day (https://data.noaa.gov/dataset/global-surfacesummary-of-the-day-gsod) of ten meteorological stations of three latitudinal ranges of Northern and Southern hemispheres (20 - 30, 40 - 50 e 60 - 70). We investigate here the variation of the daily average of the air temperature near ground during FD for each one of the three latitudinal ranges. The possible climatic effects of GCR decrease were considered using linear and cross correlation methods. The comparison between the near ground air temperature daily averages during FD events periods and equivalent periods without FDs (during solar minima years of 1987, 1996 and 2008) was also performed. Some results for the Northern hemisphere have showed a latitudinal dependence of the induced ionization by GCR on the atmospheric parameters. It was possible to note the anti correlation between the surface temperature mean and the GCR flux, increasing from low to high latitudes. However, for the Southern hemisphere, the anti correlation between these data was only found for the high and medium latitudes, also with a poleward increase. From these results it seems that the FD effect on climate is more prominent in the Northern hemisphere and that there is increases with latitude. | |||
