The first atomic bomb killed 7 1379 people and injured 68023 people in Hiroshima.

The second atomic bomb killed 35,000 people in Nagasaki, injured 60,000 people and left 5,000 missing.

On August 2nd, the B-Z9 bomber of the 509th Brigade carried the assembled atomic bomb on Tianning Island, USA, waiting for the right weather. On the 2nd, 3rd and 4th, the weather was always bad, cloudy and sometimes rainy, so the plane could not take off. The US Supreme Command is very annoyed and anxious about this, and sends weather reconnaissance planes to take off every day for observation. On August 5, the meteorological department of the US military analyzed a large number of meteorological data and predicted that Hiroshima would be sunny after rain on the 6th. Both the aircrew and the ground crew made preparations in advance. Sure enough, in the early morning of the 6th, the weather reconnaissance plane reported that Hiroshima was sunny, with few clouds and good visibility. So, near 3 am, the plane carrying the atomic bomb and other planes took off from the base in the night. Under sunny and cloudy weather conditions, American planes dropped the first atomic bomb on Hiroshima. Hiroshima suffered a devastating bombing, causing heavy casualties. According to the data of the United States and Japan, the first atomic bomb killed 7 1379 people in Hiroshima, injured 68,023 people, and all industrial machines were destroyed. The success of air strikes is due to the outstanding role of meteorology. According to the United States, due to the good visibility in the atmosphere, the throwing deviation of a five-ton atomic bomb is only 240 meters.

When the first atomic bomb raid was successful, because Japan did not surrender immediately, the United States planned to drop a second atomic bomb, targeting Kokura. The raid date was originally scheduled for August 1 1, but according to the weather forecast of the US military meteorological department, it will be sunny only on the 9th, followed by five days of bad weather, so it is impossible to drop an atomic bomb. On August 8, the former Soviet Union declared war on Japan. Considering various factors, the US Supreme Command decided to advance the bombing date to 9th. At about 4 am on the 9th, two weather reconnaissance planes and two bombers took off from the US Air Force Base and flew to Kokura. After arriving over the small warehouse, the weather was not as sunny as predicted by the military meteorological department. The whole sky is overcast and foggy, and the pilot can't see the target with the naked eye. According to General Ashworth, who was in charge of bombing at that time, the bomber lowered its flying height five times in a row and tried to throw it, but the visibility was too poor to find the target, so the plane had to fly to Nagasaki as planned.

Unfavorable meteorological conditions prevented the small warehouse from a disaster.

When the bomb-carrying plane arrived over Nagasaki, it was found that Nagasaki was also covered with thick clouds, and the meteorological conditions were much worse than predicted, so it was impossible to drop bombs visually. However, at this time, the fuel of the aircraft is running out, and the fuel tank and fuel pump are not smooth in time, so it is impossible for the aircraft to take the bomb back to China. The pilot received the order to drop the bomb, so he temporarily decided to use radar to identify and find the target. After hovering for about 10 minutes, the bomber is ready to drop the bomb. At this time, a gap suddenly appeared in the clouds over Nagasaki, and a runway in the valley could hardly be seen through the gap. So at 10: 58 local time, the second atomic bomb was dropped on Nagasaki. Because Nagasaki is located in the valley, the meteorological conditions were not good and the visibility was poor, which made the bombing deviate from the target by about 2000 meters. In addition, there was no wind that day, so the casualties and material losses caused were smaller than those in Hiroshima. According to the information provided by Japan, the atomic bomb killed 35,000 people, injured 60,000 people, disappeared 5,000 people and left 68 people. 3% of the factories were destroyed.
