| contents | The solar cycle in the temperature of the tropical stratosphere Ana G. Elias Nieves Ortiz de Adler Ciencias de la Tierra solar cycle Stratospheric temperature A search for a relationship between tropical stratosphere temperature anomalies at 10 hPa (~30 km), during 1964-1996 andthe F10.7 cm solar flux has been carried out. The long-term trend and the Quasi-Biennial Oscillation influence over four seasonaland the annual temperature series were removed. The linear correlation coefficients, r, between temperature and F10.7 for the fiveseries fall between 0.02 and 0.31, which suggests that the association between temperature and solar cycle is weak. However,when the data of each series are grouped according to solar cycle, temperature as a function of F10.7 shows a non-randombehavior similar to a hysteresis loop. The sense of rotation, axis and area of a hysteresis loop are different for each solar cycle. Thetime shift between temperature and solar flux increases from cycle 20 to 22. The correlation between temperature and F10.7becomes progressively lower from cycle 20 to 22. This suggests that the stratospheric temperature is determined not only by thesolar flux, but also by parameters such as ozone and CO2, and feedback mechanisms between them. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843101 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.43 |
