Effects of total eclipse of the sun in november 12th, 1966 in Bagé (RS), Brazil, on the meteorological parameters

Resumen

This work presents the evaluation of the thermal sensitivity index and global radiation during the total eclipse of the sun on November 12th, 1966, in the city of Bagé, RS, Brazil, located in the central line of the totality range of the eclipse. Temperature (oC), relative air humidity (%), cloudiness and wind speed were acquired in the international airport of the city for the calculation of the resultant temperature index by using Missenard’s method (1948). Global radiation data was obtained from Eppley spectral radiometer. The results showed a variation in thermal sensation, due to the decreased global radiation and corresponding decreased temperature and increased relative humidity during the eclipse.
