Rain isn't just a soothing sound. It also helps calm the winds. How? - Friction. That's according to a new study published in "Science" on February 24th.
Winds and even the atmosphere jet-streams (caused by the rotation of the planet) dissipate much of their energy via friction already. Air molecules hurd hither dither and yarn (???) rub together and warm-up. But rain and other forms of precipitation rub against air molecules too and produce a tiny bit of friction. That resistance slows each drop's fall, and also slows the winds' themselves. Raindrop (??) hasn't been measured before but using satellites' scientists' found that this friction averages 1.8 watts per square metre in the Tropics. And that adds up on a global scale. Thanks to climate change even heavier downpours' that originate higher in the sky are expected in the future. That means even more friction and potentially less of the wind that mixes the atmosphere. Of course the extra heat trapped by human greenhouse gas emissions is likely to play a bigger role than raindrop friction and any atmosphere changes. It's going to be a more humid wetter world. Better get a raincoat!
