What kind of cold and snowy weather did Shenzhou IV encounter?

The test of Shenzhou IV has been going smoothly, and everyone is very happy. At this time, unfortunate news came from the international space community again. On November 28, 22, when the launch of the French "Ariane -5" carrier rocket entered the 1-second countdown, the launch was forced to be postponed due to the failure of the refrigeration ignition device. On December 11th, the "Ariane -5" carrier rocket was launched again. Only 3 minutes after the rocket was launched, it exploded in the air, and the communication satellite carried on the rocket fell into the Atlantic Ocean in the fire!

The unfortunate news once again gave the participants a sober shot, and they prepared for the launch more seriously for fear of any negligence. However, the day was not as good as people wanted, and the official launch was about to take place, but a heavy snow flew in the air.

The cold snap in Siberia came overnight. The cold current first swept across Europe, then crossed the mountain pass in the east of Tianshan Mountain and rolled all the way. As a direct result of the arrival of the cold current, the people at the launch site just woke up the next morning and found that the heavy snow had covered the entire launch site.
