To understand and predict the climate system, we must have a high-quality climate system model. As a valuation of quality, global energy budget and water vapor budget are very important component. This research is an analysis of the model atmosphere energy budget and transportation from ocean atmosphere to land atmosphere by means of between the energy and water vapor relation for the AMIP Ⅱ period, 1979.1 -1996.2, simulated with Yonsei University Atmospheric General Circulation Model with 7 vertical levels(below YONU AGCM Tr7). Most principal climate models had been participating the AMIP, do intercompare the models, and do asses their quality. This data used in this research is the YONU AGCM Tr7 AMIP Ⅱ standard output that is submitted to th AMIP Ⅱ. For verification of the output is NCEP/DOE (National Centers for Environmental Prediction / United States Department of energy) reanalysis data. When we study the simulated normal fields of energy flux components and patterns of the golbal distribution, we can find remarkable improvement on the model quality achieved by some development and error correction of YONU AGCM Tr7. Especially analysed atmospheric energy imbalance during AMIP Ⅱ period is downward 9.4 W/㎡ at the top of the atmosphere, downward 1.4 W/㎡ at the surface, thus 8.0 W/㎡ at the atmosphere. When we consider the global atmospheric energy imbalance, we can infer that the land atmosphere have 17.7 W/㎡ energy deficit, the ocean atmosphere have 6.7 W/㎡ energy surplus. According to energy deficit and surplus, the energy of the transportation from ocean atmosphere to land atmosphere is 2.5PW(PW= 1015 W). This value is the same level energy from low latitide to high latitude according to ocean and land. To investigate how the latent heat do contribute the energy flux from ocean to land, we calculated runoff by YONU AGCM Tr7. So we could get that the estimated latent heat is 3.2PW. This is apparently lager than total energy flux, means that the energy follow from land to ocean by means of the form of entalphy and geopotential energy. This result confirm that the stream of the energy and water vapor between ocean and land does have closely relation.
