Show From Arctic to Antarctic Vast Army of Weather Experts Work for the United States Combined military operations plans are contingent on ideal weather weath-er conditions for all four participating participat-ing combat sections: air, ground, sei and amphibious. Weather plans for air operations must include pre-invasion pre-invasion conditions for softening up as well as air support on the invasion inva-sion day. Ground conditions will include in-clude soil trafficability, whether or not soil will support movement of heavy vehicular equipment, air stability sta-bility ad wind velocity, for use of chemical warfare, smokescreens, etc. Sea conditions must be favorable favor-able enough to permit the large ships to launch small craft with safety safe-ty and amphibious commanders are concerned with on-shore and offshore off-shore winds and surf conditions. So the weatherman's task is to discover dis-cover conditions which will be most nearly ideal for all four operations and how many days such conditions will prevail. Plans can then be made accordingly. By comparing the current day's maps with the finger-print maps, chosen by weather experts from those maps indicated by the card-machine card-machine selection, the past weather weath-er most nearly like that of May 15, 1945, is chosen. It may have been February 23, 1929. With this map and the map for the succeeding days in 1929, the weather expert can see how the high and low pressure groups moved, can study other me-teoimogical me-teoimogical data. |
