He was appointed director of Weather for the Army Air Forces and the U.S. Army early in 1942 and organized the weather service for the global extent of World War II during the first year of participation by the United States. He then attended the Army's Command and General Staff School at Fort Leavenworth, commanded a light bombardment group and was in the first class of the Army-Navy Staff College created by the Joint Chiefs of Staff in 1943.

OPINIONS, TASTES AND EVALUATIONS
Interest in and reads on philosophy, ethics, national and foreign affairs; has a lively interest in art and architecture; in travel he prefers France, Germany and Japan and highly oceanic climates in the middle latitudes; has visited most of the national parks in the United States and loves the mountains, particularly the snowcaps of the Middle West.
In July 1931, while flying a Thomas Morse O-19, the first Air Corps plane with a metal fuselage, during a dive bombing training mission, the bomb release gear stuck and while attempting an abrupt pull out, the airplane grazed the ground, did three complete rolls and lit right side up minus the landing gear and with the upper wing sagging down on the lower wings of the biplane. The engine was located a quarter of a mile down the beach. The officers and men on the ground at the bombing range rushed to the wreck expecting to find Lieutenant Zimmerman dead. When they arrived, he was crawling back to the cockpit looking for the first sergeant who had been thrown back to the conigle tail section of the metal fuselage. Both survived the crash due to the ruggedness of the new metal fuselage.
