SHEAD WNU Staff Correspondent. There is one thing in which the nation's farmers and our military, leaders have a common com-mon stake ... an element which can upset the most carefully laid military plans and the most meticulously planned agricultural program the weather. The farmers' success in planting and harvesting and American combat success in i j combined land-sea-air opera- tions can come only through close observance of the scientific scien-tific predictions of the weatherman. weath-erman. For the weather is i often used as a military weapon weap-on by our military strategists, and our farmers are dependent depend-ent upon the vagaries of the weather to harvest a record production, or a crop failure. No military operation whether it , Is a minor sortie by a group of fighters, fight-ers, a bombing mission on an enemy j city, naval bombardment of a Jap i island, a ground attack in China, or a large scale invasion is never blueprinted blue-printed unless latest weather information infor-mation is first consulted. Success of an attack is ofttimes dependent upon clear weather, though American forces have profitably exploited bad weather to make offensive strikes against the enemy. Our military strategists were quick to recognize the importance impor-tance of accurate meteorological data, and so have greatly expanded ex-panded the network of observation observa-tion posts, trained thousands of officers and enlisted men and adopted new technological devices de-vices to guarantee reliable forecasts. fore-casts. Together, the AAF, the navy and the U. S. Weather bureau weather systems form a vast network of information, research, observation and forecasting reaching from the United States to all parts of the world. Observation units vary in size from two men occupying a hut on an isolated Atlantic or Pacific isle to a major research station with a full staff of specialists. The AAF maintains several major research centers and more than 1,000 observation and forecasting stations reaching from the Arctic to the Antarctic, and its weather report system spreads and moves as rapidly rapid-ly as the fighting fronts. The nerve center of this vast, scattered weather weath-er force is in the Pentagon building build-ing in Washington where approximately approxi-mately 250 persons watch the weather weath-er in all regions of the world and prepare long-range forecasts and special studies to guide our high strategy planners. Navy Maintains Stations. The navy maintains about 1,400 observation and forecasting stations, including about 14 major weather "centrals." In some instances aerological units maybe aboard flagships or aircraft carriers, or on advanced island bases and the units may consist of one man on a small ship or a full-fledged "central" with a full complement of 100 or more officers and men. How the navy weather bureaus have grown since 1940 may be seen by the fact that in that year navy aerology under the bureau of aeronautics aero-nautics consisted of less than 200 officers of-ficers and men in about 50 units, whereas today the personnel totals about 6,500 officers and men assigned as-signed to the 1,400 units. The AAF staff of weather specialists numbers 20,000 officers and men, and the force of observers alone has grown from 50 to 10,000. Service provided by these thousands of forecasters ln- ii ' ... . . -' : 3 lK:V;;- :;--V.:::v-..;::.-:.v y j 1 ': "ik 'VIM fi I r-:.'-v::::: ; ; a r::-r.-.7;:tfiv:. l., .. . ' ' would encounter rough seas on the journey from North Africa. But at the same timo our forecasters predicted pre-dicted tranquil waters in Sicilian harbors, and the almost miraculous calming of the seas as our landing craft neared the Sicilian shores has become a military classic. Admiral Halsey took advantage of the cover of a "zero-zero" storm after aft-er raiding the Marshall and Gilbert Islands. With visibility zero and ceiling zero, his ships, large and heavy enough to ride out the storm, were meanwhile safe from enemy air attack. At Rabaul detail plotting of the upper air strata enabled our forces to lay down a smoke screen to blot out our vessels and our planes from Japanese ack-ack and dive bombers. bomb-ers. Low wind velocity was required so that our screen would not suddenly sud-denly veer and cover our target instead. in-stead. Conditions were exactly as predicted and ordered. Many other Instances of the use of weather forecasts by our militarists are given, for instance in-stance in the Normandy invasion, inva-sion, weather was bad and the sea choppy, but the forecasts were that severe conditions would prevail for at least 21 days after the D-Day chosen. Axis Are Weather Conscious. Both Germany and Japan are extremely ex-tremely weather conscious and both have used weather, particularly bad weather, to screen their activites. For instance, Germany's battle of the bulge in the Ardennes was undoubtedly un-doubtedly arranged to coincide with bad weather that would keep our superior su-perior air strength incapable of decisive de-cisive blows, while German ground forces, numerically stronger at that point, smashed through. A clearing break in the weather came ultimately ulti-mately and our air power went into action to help stop the German offensive. of-fensive. According to the navy, the Japs are not as far advanced in weather technique as either Germany or our own military. In at least one Instance a Japanese plan of action did not work out as scheduled because be-cause of their weather miscalculations. miscalcu-lations. s They attempted to bring reinforcements to New Guinea under un-der a storm front so that our planes could not spot their movements. An unexpected or miscalculated shift dissipated the storm front. The troop and supply armada was spotted spot-ted by our reconnaissance planes. They were attacked and destroyed by the AAF in the famous Battle of the Bismarck Sea. Methods used by various countries in weather forecasting vary. The AAF and the navy use the Norwegian Norwe-gian theory of air masses and polar fronts and the long scries of daily weather charts of the world prepared pre-pared by the weather bureau as a basis. Research Essential. Almost endless research was neo-cssary neo-cssary to code the world's weather data.

Weather Important Weapon. According to our military men accurate ac-curate evaluation of weather, plus the constant flow of up-to-the-minute meteorological information from all theaters of war, make it possible to use weather as an important weapon. weap-on. Cited as examples of weather strategy is the Sicilian invasion.
