Chapter 2 Blue-sky Dreamers
These guys are all up in the air. They may seem like a bunch of dreamers, but the stuff they get up to affects our daily weather. Meet Atmosphere who envelops Earth in its huge gassy blanket and plays host to these Blue-sky dudes. You’ll find Jet Stream whizzing around here and Weather Front along for the ride. Cloud shows up when water vapor in the air reaches its dew point and forms liquid droplets. Things really get going when Wind blows in —you can feel Atmosphere then. Pressure’s highs and lows reflect the shifting weight of Atmosphere’s constantly moving gases, giving us clues to what’s coming up . . . 22
