Summary
| Description |
English: This chart from September 1949 shows the United States Weather Bureau's prediction for where the Soviet Union first tested its atomic bomb in 1949. Each colored zone indicates the probability that the bomb was detonated within that area. This is one of several maps, each one showing slightly different probabilities depending on the exact date the bomb was assumed to have gone off (this one uses the date now known to be correct). The analysis was done by extrapolating backwards from assumed wind patterns. |
