2. Describes the computational and human resources required to effectively conduct climate modeling in the United States to meet the needs of the climate applications, policy, and scientific communities.

The panel therefore notes that the lack of a suitable sustained observing system for climate limits progress in climate modeling. COMPUTING RESOURCES The building of parameterizations of individual model elements; the running of uncoupled atmosphere, land, and ocean models; and the diagnoses and analyses of coupled climate model outputs can be accomplished at the workstation level.

. The panel concludes that parallel vector computers provide superior processor speeds, greater usability, and lower human resource requirements; however, the massively parallel commodity processor machines are currently the only ones that can be purchased in the United States.

able to instill such a culture or otherwise provide the focus required for regular climate product production. Analogous to operational weather forecasting, centralized climate modeling activities and the maintenance of a climate observing system should exist outside the research domain but should have a close interaction with the research community.

climate modeling effort so that it can respond to societal needs, the panel recommends that enhanced and stable resources be focused on dedicated and centralized operational activities capable of addressing each of the following societally important activities: 1. short-term climate prediction on scales of months to years; 2.

This strain on human resources has resulted in declining graduate enrollments in all areas of the climate sciences and in the growing disparity in the quality of life of scientists especially young ones and their private sector counterparts. The shortage of highly skilled technical workers is, however, not unique to the climate modeling community; it is part of a larger shortage affecting nearly all areas of science and engineering except those with strong linkages to the private sector.

recommendations on the most effective form of institutional and governmental organization to produce and deliver climate information for the public and private sectors. VISION FOR THE FUTURE The panel envisions an operational entity or entities that would create and deliver climate information products of benefit to society.
