Storms, polar deposits and the methane cycle in Titan's atmosphere.
In Titan's atmosphere, the second most abundant constituent, methane, exists as a gas, liquid and solid, and cycles between the atmosphere and the surface. Similar to the Earth's hydrological cycle, Titan sports clouds, rain and lakes. Yet, Titan's cycle differs dramatically from its terrestrial counterpart, and reveals the workings of weather in an atmosphere that is 10 times thicker than the ...
متن کاملPrediction of Magnetic Storms by Nonlinear
The strong correlation between magnetic storms and southward interplanetary magnetic eld (IMF) is well known from linear prediction lter studies using the Dst and IMF data. However, the linear lters change signiicantly from one storm to another and thus are limited in their predicting ability. Previous studies have indicated nonlinearity in the magneto-spheric response as the ring current decay...
متن کاملThe Electric Current-systems of Magnetic Storms
1. This paper continues my discussion of the average characteristics of the field of geomagnetic disturbances or storms, given in two previous papers • which will be referred to as I and 2; the irregular part of magnetic disturbance is not considered. A condensed representation of the main average features of magnetic storms is given in 1 (pp. 61-72) and 2 (pp. 242-264), and evidence is describ...
متن کاملThe size of the auroral belt during magnetic storms
Using the auroral boundary index derived from DMSP electron precipitation data and the Dst index, changes in the size of the auroral belt during magnetic storms are studied. It is found that the equatorward boundary of the belt at midnight expands equatorward, reaching its lowest latitude about one hour before Dst peaks. This time lag depends very little on storm intensity. It is also shown tha...
