For the AMIP experiment, the model atmosphere, soil moisture, and snow cover/depth were initialized for 1 December 1978 from a previous model simulation.
AMIP monthly sea surface temperature fields are prescribed, with daily values determined by linear interpolation.
The ice may occupy only a fraction of a grid box, and the effects of the remaining ice leads are accounted for in the surface roughness length, shortwave albedo and longwave emission, and turbulent eddy fluxes (see Surface Characteristics and Surface Fluxes).

 PILPS Phase 3   (Site not responding. Last check: 2007-11-06)
AMIP, another initiative of the WCRP, is a widely implemented protocol for testing the performance of atmospheric general circulation models (AGCMs) under common specifications of radiative forcings and observed ocean boundary conditions (Gates 1992; Gates et al., 1999).
In the AMIP I global models, the land-surface schemes were solely boundaries for energy and water exchanges between the air and the land.
In the current AMIP II phase of the intercomparison, the experimental design remains fundamentally the same as AMIP I, except that the simulation period has been extended to 17 years (from 1979 to 1995).

 SURFACE AIR TEMPERATURE SIMULATIONS
The AMIP experimental design required that all modeling groups submit, as Standard Output, monthly-average grid point values of 57 variables (Gates 1992b) for the 10-year period 1979-1988, one of which is surface air temperature.
N for 1979-81 with a larger sea ice area as the boundary forcing of the AMIP simulations resulted in a colder mean climate of land air temperature simulations in high latitudes, compared to the rest of years in the period.
The 1979-88 time-series of monthly mean global land air temperatures averaged for the 16 selected AMIP simulations and as observed in the upper panel, and average monthly and annual mean errors of the simulations relative to the observations in the bottom panel.

 Role of the islands in the climate of the maritime continent   (Site not responding. Last check: 2007-11-06)
As shown in the AMIP II experiments, the UM is unable to simulate well the mean climate over the maritime continent in terms of both the precipitation distribution and the circulation.
The first is equivalent to the standard AMIP II experiment integrated for the full 17 years of the AMIP period but with additional diagnostics.
In DJF there is an increase in precipitation off the coast of the western islands of the maritime continent and a decrease in the SPCZ region and north of the Australian continent, reducing the strength of the winter monsoon.

One of the many studies facilitated by the AMIP is the evaluation of model simulation of processes at the land surface, a key locus of human interaction with the climate system.
Of the monthly mean land-surface variables available from these AMIP simulations, the spatio-temporal variability of continental evaporation shows the greatest sensitivity to the LSS representation of hydrology.
Moreover, in twin AMIP simulations where this representation is changed from a simple "bucket" scheme to a biophysically based formulation (while retaining the same atmospheric model and land-surface characteristics), there is a general reduction in the RMS errors of the continental climate simulation relative to the reference data.

 EVALUATION OF AMIP SOIL MOISTURE SIMULATIONS
A complete diagnosis of the AMIP hydrological cycles is not possible at this time, as runoff was not included in the Standard Output.
In the first place, the land surface schemes in AMIP are fully coupled with the GCM atmospheres, so that they are free to seek and feed back on their own model climates.
The differences we find between AMIP model output and observed soil moisture may therefore not be due to the diversity of soil moisture schemes alone.

AMiP is PRAGMA's best practice methodology, developed with partial funding from the Department of Trade and Industry's Competitiveness Fund, designed to improve the asset management practices and increase the maturity of teams involved in asset management optimisation.
The following day was devoted to going through the AMiP best-practices benchmark, followed by a day in which improvement actions were defined and the results were discussed among the project team.
He adds that AMiP aligns the company's asset management strategy with business strategy, tests the maturity of asset management processes, sets goals for improvements in a broad asset management improvement master plan and follows through to the actual implementation of the plan.

 ACTIVITIES OF THE CAS/JSC WORKING GROUP   (Site not responding. Last check: 2007-11-06)
Climatological comparisons are available for nearly every standard AMIP model output field, and probably represent the most comprehensive source of the climatologies of atmospheric circulation models.
AMIP research is structured round a series of diagnostic sub-projects and a clear view of how models have evolved since AMIP began nearly a decade ago has emerged.
It was considered that AMIP should evolve into an ongoing activity, with modelling groups submitting updated (standard) runs with new versions of their models every few years and that a centralized library of these simulations (including a model median) should be maintained as a gauge of progress in atmospheric modelling.

 What is AMIP   (Site not responding. Last check: 2007-11-06)
AMIP is the acronym for the Atmospheric Model Intercomparison Project, organized as part of the World Climate Research Program by the Working Group on Numerical Experimentation.
This is an international program to perform an intercomparison of results from different General Circulation Models (GCM) of the atmosphere to determine the systematic errors in the climate predicted by these models, for the decadel period 1979-1988 using realistic boundary conditions.
This entails using the same observed distributions of sea surface temperature and sea ice in the 29 participating GCM's.

 An Overview of PCMDI
In this project, some 30 AMIP modeling groups are simulating the climate of the decade 1979-1988 using the observed monthly sea-surface temperature and sea ice, as well as common values of solar luminosity (1365 W/m^2) and atmospheric carbon dioxide concentration (345 ppm).
The participating models' principal numerical algorithms and dynamical/physical parameterizations are summarized in AMIP model documentation.
The results of this diagnosis and intercomparison of the AMIP model simulations were extensively discussed at an international AMIP Scientific Conference in May of 1995.

The same archive from the climate run used above was compared to the AMIP archive runs for Jan.-Feb./83 and Jan.-Feb./87 and the average HRs are plotted on Fig.3.1 ; all runs were for T42 truncation.
Note that the AMIP results are significantly more similar to each other than to the climatology results indicating substantial impact of the SSTs on the resulting heating rates.
Fig.6.1 and Fig.6.3 show the average heating rate and temperature amplitudes respectively of the two experiments and their differences in terms of planetary wave number and pressure.

Participating modelling groups are requested to use the same model version (or as similar as possible) as they used for their AMIP 2 submission.
In addition to the traditional AMIP 2 standard output participants are also strongly encouraged to provide information suitable for input into the ISCCP cloud simulator of Klein and Webb and hence provide more detailed information on the behaviour of the clouds.
It is strongly urged that the SST field used in construction of the ‘q flux’ be the AMIP2 climatological SST field.

In particular, zonally averaged ocean surface heat fluxes resulting from various AMIP simulations were intercompared, and to the extent possible they were validated with uncertainties in observationally-based estimates of surface heat fluxes.
Here the authors will only look at 10-year means of the AMIP runs, and for simplicity they assume that any long term imbalance in the global averaged N{sub sfc} will be sequestered (or released) over the global ocean.
Tests have demonstrated that the treatment of how the global average energy imbalance is assumed to be distributed is important, especially when the long term imbalances are in excess of 10 W m{sup {minus}2}.
