还等夏天吹东风呢?呵呵。 每天都放2次呢,光阿拉斯加,每天就放14个。
Around the world, twice a day, everyday, more than 700 weather balloons launch into the air. 14 of those balloons are released across Alaska, tracking things like temperature, humidity and wind speed.

Twice a day, every day of the year, weather balloons are released simultaneously from almost 900 locations worldwide! This includes 92 released by the National Weather Service in the US and its territories. The balloon flights last for around 2 hours, can drift as far as 125 miles away, and rise up to over 100,000 ft. (about 20 miles) in the atmosphere!
The balloons, which start out measuring about 6 ft. wide before release, expand as they rise to about 20 ft. in diameter!
