Investigations in the field of general meteorology have been and continue to be restricted and handicapped by the fact that there are not available to investigators daily charts of the world's weather. It is necessary in investigations in meteorology and particularly in weather forecasting that problems now but imperfectly understood be considered from a world‐wide viewpoint, for there can be no doubt that much that we call “weather” is not of local origin, but has its inception in the general actions and reactions that involve at times the atmosphere over an entire hemisphere and possibly both hemispheres. Hence, investigation based on a study of daily synoptic charts for a limited area, such as Europe, the United States of North America, or of India, can lead to but an imperfect understanding of the general physical processes that are in operation to produce our day‐to‐day weather. Moreover, when it is understood how rapid are the changes in speed, direction of movement and magnitude of areas of high and low barometric pressure, there arises the natural desire to look into the observable facts over a world‐wide area in an attempt to determine the causes of them. Meteorology without a world‐wide weather map is laboring under difficulties as great, or greater, without realizing it, than astronomy without its star charts. Hence it is contended that many of the important problems of meteorology will not and cannot be solved until there be available daily synoptic charts of the various meteorological elements of, relatively speaking, the entire world. It would redound to our credit if the American Geophysical Union should become instrumental in bringi
