These improved measurements are analysed as equivalent latitude zonal means. Major interhemispheric differences are revealed in the water vapour content of the vortex in the lower stratosphere. This technique emphasises mixing ratio gradients at the edges of both polar vortices, and a local maximum at the edge of the Antarctic vortex. There are some small interhemispheric differences in mixing ratios in mid-latitudes, but they are not strongly related to the dehydration of the Antarctic vortex. A mixing ratio gradient across the interior of the Antarctic vortex at 530K indicates it is not isentropically mixed. A strong local maximum in mixing ratio at the centre of the Antarctic vortex in the mid-stratosphere indicates it is not well mixed in the mid-stratosphere also. There is little evidence of significant structure inside the Arctic vortex.

Its purpose is to let people work as freely as possible in the knowledge that they are both working within the bounds of the law of copyright and respecting the rights of others.

Recent research (Chen et al., 1995) has also suggested the possibility of a barrier to transport at the equator. In this thesis the effects of possible transport barriers and related mixing processes are studied using water vapour and ozone mixing ratio data from the Microwave Limb Sounder and assimilated-wind data from the UK Met-Office. Interhemispheric differences in the zonal mean of water vapour mixing ratios are studied on equivalent latitude. Results indicate that the southern vortex of latewinter 1992 was fairly well contained at 530K, and not acting like a "flowing processor". The northern vortex of late-winter 1993 also appears to have been well contained, but a significant amount of air appears to have been mixing across the edge of the northern vortex of late-winter 1992. The southern vortex of ...

LD can be supplemented with other models such as QTI to create a platform-independent definition of a set of highly interactive learning materials. It is not necessary to have a complete set of off-the-shelf solutions to do very useful things with LD. Users will sometimes be happy managing XML source if they are given suitable templates to work from. Applying an LD approach can also give significant advantages for the management of content-development projects.

Using user surveys and custom analytics we have found out who wants and uses what, and on which devices. Now we are applying that intelligence, creating a new desktop and mobile portal, designed to meet the needs of the 2015 user, and to play a strong connecting role in the whole online student experience.

Attendees will be asked to imagine adding their dream analytics solution to their portal. What should it record, and what reports and visualizations should it generate? We will show how these desired capabilities can be implemented in a practical solution.
