【摘要】 根据1978年3月18日的典型的亚暴事件数据,检验了A_E指数作为估计全球焦耳热生成率的精确度.
【Abstract】 The accuracy ofthe A_E index as a measurement of the joule heat production rate is examined for a typical substorm event on 18 March 1978 by estimating the global joule heat production rate,as a fuction of time,using data obtained from the IMS six meridian chains.In spite of the fact that the A_E index had an initial slow growth which was followed by a rapid growth,the joule heat production rate attained a high level during the slow growth and thus their variations were considerably different from those of the A_E index.Therefore,although the A_E index is statistically linearly related to the global joule heat production rate,one should be cautious in assuming that details of time variations of the A_E index during individual events represent those of the joule heat production rate.
