"Computer simulations didn’t find significant climate change fingerprints in the reduced rainfall, which was low but not too rare, Otto said. But #evaporation of #water in lakes, rivers, wetlands and soil “was much higher than it would have been’’ without climate change-spiked temperatures, she said."
This fluid, seemingly at rest initially, turns out to be convecting as revealed by a #timelapse movie. #Evaporation cools the fluid at the surface, which makes it a bit heavier than the fluid below, thus #convection ensues, very slowly!
This fluid is #rheoscopic, easy to make at home using shaving cream.
1/34 This started out as a much shorter thread about a related topic, but Something Happened and now it's a #LifeHack#instructional thread on keeping your house comfortable and saving #money and the #environment, through the magic of air movement. It's also timely, what with it being the start of the northern-hemisphere summer and southern-hemisphere winter.
5/34 Another one doesn't get as much attention as some of those do. It's this: your home's air will feel more #comfortable at a given temperature and humidity if it's moving.
When #heating, air movement keeps the air from stratifying, leaving a cold layer near the floor that makes your feet feel like they're freezing.
When cooling, it also does that, but in addition, moving air is better at evaporating #moisture from your #skin, which increases the cooling effect of that #evaporation.
