"Worldwide, there are about 1,300 upper-air stations. Observations are made by the NWS at 92 stations - 69 in the conterminous United States, 13 in Alaska, nine in the Pacific, and one in Puerto Rico.
NWS supports the operation of 10 other stations in the Caribbean. Through international agreements data are exchanged between countries worldwide."
This seems to suggest that NWS does not operate those over China but the map simply shows all the balloon weather stations that are part of this system.
1. The next bus is right around the corner or I have my transit App to give an idea about delay if I cannot see the next bus yet. generally the delay is of teh order of 2 ~ 3 minutes.
2. The next bus is also has less people and the journey is thus more pleasant.
Things do screw up at times though. This weekend, a driver did not stop and indicated that there was a bus following him. The App showed the next bus was 20 minutes behind. I had to catch a different bus after that. I hope this does not happen on working days.
