9:00-9:30 Introduction
9:50 G. Schmidt
- GISS Model (NASA, Columbia-U(CCSR))
- Interests: paleo-proxies
- Cloud Processes, Strato-Tropo-Exchange
- D: -650per mil, O: -120~-240 per mil (observed)
- Rayleigh model: -800 permil
- 23-layer model: -770 permil
- 20-layer model: -675 permil
- Science (Webster and Hymsfields)
- Comparison with Cappa et al., 2003
- Evaporative cooling is taken into account. New coefficients are
suggested
- Simulated meteorogic line is now, D=8*O+13
- Does it mean that GCM world is not true ? (Henderson-sellers)
- Splay.
- Does not affect D in stratophere (Obvious, because of parallel
(several permil) change)
- Antarctic precipitation is sensitive to different cloud processes
parameterization.
- Even wrong magnitude, wrong change sign. <- highly dependent
on micro cloud physics.
- Foram delta-18O-carbonate
- LGM vs Present
- Not so much different (?)
- Core (LGM-PR)- Model(LGM-PR)=1 permil
10:55 D. Noone
- Tag
- Antarctica, AAO, Vortex
- More interest on meteology.
- NCAR CCM (Typical water physics)
- Has a explicit hydrologic cycle (when and where water exists
can be traced)
- Paleo-main focus
- cloud processes
- Ground hydrology.
- Why NCAR wants to develop iso-GCM (Ann)
- Wants to say how bad the model is by isotopes.
- Aim to develop biospheric model.
- ISOLSM
- leaf del180 has daily change (10 permil)
- stem does not.
- Looks not reasonable!
- Open Code for comunity.
12:20 J. Brown
- MUGCM
- River Discharge
- Coral
- del18Ocoral=del18Oocean + a*SST+ b
12:45-14:00 Lunch
14:15 A. Henderson-Sellers
- What is scientific question?
- Isotopes are useful for improve GCMs?
14:40 Yoshimura
15:40-15:55 Break
15:55 M. Werner
- ECHAM4
- Advection scheme, vapor and liquid phase
- PMIP: Big differences between AGCMs
- Moisture sources: LGM & Present has not big change in
Greenland.
- Quite lots of works has been done. Maybe the most progressed.
17:10 P. Valdes
- Hadley Centre Model (HadCM3)
- Targets: 8.2kyr depletion & glacial-intergrlacial transition
