Abstract: | The effect of the equatorial electrojet is sufficient to reduce the probability of an abnormal quiet day occurring at Addis Ababa, Trivandrum and Alibag. Addis Ababa AQD occurrence exhibits an anomalous or subdued relationship to solar intensity, compared to that of Alibag, Trivandrum, and Greenwich/Abinger/Hartland; this is thought to be due to some unknown characteristic of the PM electrojet. Few AQD's are common to Addis Ababa and Trivandrum, Addis Ababa and Alibag, and Trivandrum and Alibag compared to the number common to Abinger and Wingst. |
