Short- to medium-range weather forecasts were prepared by Soviet meteorologists for the Battle of Stalingrad. These included forecasts for days suitable for massing troops and equipment and for starting the Soviet offensive in November 1942 that resulted in the encirclement of the German 6th Army. Another forecast was connected with the operation of artificial thickening of the ice cover of the Volga River in the Stalingrad area that made it possible to drive tanks from the east bank to the west bank of the river (width: about 1 km).
In January 1943 a German Panzer army had to be withdrawn from the Caucasus. To accelerate the retreat, light elements of that army crossed some 42 km of the ice cover of the Gulf of Taganrog (Sea of Azov). The crossing was authorized after a meteorologist proved his estimate of the ice-cover thickness by landing in a light plane on the ice.
In January 1945 weather forecasts played an important role in the major Soviet (2 200 000 troops and 5 000 warplanes) Oder-Vistula offensive. Marshal Konev writes with appreciation of the correct weather forecasts.
In the Appendix, considerations that led German meteorologists to formulate a forecast for a minimum of five days of fog or low clouds from the Ardennes to southern England are reviewed. This forecast was used by the German High Command for the start of the Battle of the Bulge in December 1944.
