W. Fernandez et al., CHANGES IN METEOROLOGICAL VARIABLES IN CORONEL OVIEDO, PARAGUAY, DURING THE TOTAL SOLAR ECLIPSE OF 3 NOVEMBER 1994, Earth, moon, and planets, 74(1), 1996, pp. 49-59
Solar global radiation, air temperature, relative humidity, and wind s
peed were measured in Coronel Oviedo, Paraguay, within the path of tot
ality of the eclipse of 3 November 1994. Global radiation decreased gr
adually as the sun was being eclipsed and became negligible during the
totality, then increased to their normal values. Surface air temperat
ure decreased significantly, about 3 degrees C, with the lowest value
occurring about 7 minutes after totality. Relative humidity, because o
f its dependence on temperature, increased as a consequence of the tem
perature decrease. Surface wind speed decreased gradually during the e
clipse, as a result of the cooling and stabilization of the atmosphere
. Although atmospheric pressure was also measured, it was not possible
to record pressure changes clearly associated to the eclipse, since t
he pressure sensor was only able to detect pressure variations of at l
east 1 hPa.
