Abstract:
Among the many aspects of tropical climate, the temperature variability in the upper troposphere is of special interest. The amplification of temperature trends at the surface in the upper troposphere predicted by climate models has proven difficult to verify with observations, in particular radiosondes. An update about the progress in reconciliation of this difficulty is given.
A second major research topic is the ElNino Southern Oscillation. Thanks to the availability of new reanalyses in both atmosphere and ocean, the temporal variability of coupled atmosphere-ocean budgets could be investigated in some detail. These have revealed that during an El Nino event the additional heat emitted by the tropical Pacific is not lost to space but to a surprisingly large extent stored in the tropical Atlantic and Indian Ocean basins.
Finally preliminary results from efforts to extend the trend and budget evaluations backwards to the early 1950s are discussed.
