Abstract:
It is certain that the planet has warmed over the past 100 years, and it is as near certain as anything can be that it will continue warming. What is less certain is how the atmospheric structure and circulation will respond to that warming. In this talk I will show that we can be fairly certain about some changes — in general those that are directly associated with the thermodynamics and radiation budget — but for others, including some dynamical changes, even the sign of the change is in doubt. I will focus on the height and temperature of the tropopause and some aspects of the general circulation.
What is the Joint Oslo Seminar (JOS):
Atmospheric and climate sciences have a stronghold in Oslo among the four institutions University of Oslo, the Meteorological Institute, CICERO and NILU. This joint seminar invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field. All seminars will be held on Thursdays (Noon -1pm) and lunch (sandwiches) will be served on a “first-come-first-served”-basis.
