Abstract : The synoptic investigation carried out under this contract during the contract time from October 1956 to December 1959 at the International Institute of Meteorology, Stockholm/Sweden, had as its main aim the detailed synoptic study of the total atmospheric space from the ground up to the upper stratospheric layers which are in reach by our present radiosonde network. The whole study has been concentrated on two special selected periods in mid-winter (1 to 7, and 8 to 13, January 1956) and one period in mid-summer (15 to 20, July 1957, already using IGY-data). Methodically this investigation differs very much from other earlier synoptic-aerological studies because of its worldwide extent and because of the extensive use of the totally available radiosonde material of the Northern Hemisphere. In addition it also differs because the data have not been averaged as in most studies according to latitude or longitude circles but rather according to the main outline of the cores of the atmospheric westwind drift. Thus, the mass field of the atmosphere in three dimensions has been investigated by taking the flow field and its general character as the reference system relative to which an averaging process has been performed. This report summarizes work done under this contract.
