The solar cycle in the temperature of the tropical stratosphere

A search for a relationship between tropical stratosphere temperature anomalies at 10 hPa (~30 km), during 1964-1996 and the F10.7 cm solar flux has been carried out. The long-term trend and the Quasi-Biennial Oscillation influence over four seasonal and the annual temperature series were removed. T...

The long-term trend and the Quasi-Biennial Oscillation influence over four seasonal and the annual temperature series were removed. The linear correlation coefficients, r, between temperature and F10.7 for the five series 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-random behavior similar to a hysteresis loop. The sense of rotation, axis and area of a hysteresis loop are different for each solar cycle. The time shift between temperature and solar flux increases from cycle 20 to 22. The correlation between temperature and F10.7 becomes progressively lower from cycle 20 to 22. This suggests that the stratospheric temperature is determined not only by the solar flux, but also by parameters such as ozone and CO2, and feedback mechanisms between them.En este trabajo se busca una relación entre la anomalía de la temperatura estratosférica tropical a 10 hPa (~30 km), durante el período 1964-1996 y el flujo solar F10.7 cm. De las cuatro series estacionales y de la serie anual, se filtró la tendencia de largo plazo y la influencia de la oscilación de casi dos años (QBO). El coeficiente de correlación lineal r entre la temperatura y F10.7 para cada una de las cinco series está entre 0.02 y 0.31, lo que llevaría a pensar que la asociación entre la temperatura y el ciclo solar es débil. Sin embargo, si los datos de cada serie son agrupados de acuerdo con el ciclo solar al que pertenecen, la temperatura en función de F10.7 presenta un comportamiento no aleatorio, similar a una histéresis. El sentido de rotación, el eje y el área de cada histéresis varía según el ciclo solar. El área, proporcional al desfasaje entre la temperatura y el F10.7, se hace más grande desde el ciclo 20 al 22. Para la serie anual r es 0.83 en el ciclo 20, decreciendo a 0.62 y 0.16 para los ciclos 21 y 22 respectivamente. La correlación entre la temperatura y F10.7 se hace progresivamente menos lineal desde el ciclo 20 al 22. Esto podría explicarse porque la temperatura estratosférica depende no sólo del flujo solar, sino de parámetros como O3 y CO2 y de los mecanismos de feedback entre ellos. A pesar de la pérdida de significancia estadística, el análisis de los datos agrupados por ciclo solar permitiría detectar cambios progresivos en una dada asociación.Universidad Nacional Autónoma de México.
