These maps were prepared in 1966-67 as part of the World Meteorological Organization's Climatic Atlas Project. However, since the project has not moved as quickly as anticipated, this set of maps is being issued on an informal basis as reference material for Weather Offices. In the decade since their preparation there has not been any more up-to-date publication of pressure maps so it is believed that these maps will contain valuable and useful reference information"--Page [1]. |
