What is the rainmaking process called?
Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.
Where does collision and coalescence occur?
The Collision and Coalescence Process! Unlike the Bergeron Process, where precipitation forms under supercooled conditions, the Collision and Coalescence Process typically occurs within relatively warm clouds with tops warmer than -15C.
How is coalescence formed?
Coalescence is the process by which two or more droplets, bubbles or particles merge during contact to form a single daughter droplet, bubble or particle. It can take place in many processes, ranging from meteorology to astrophysics. In meteorology, its role is crucial in the formation of rain.
Why droplets deform as they fall through the air?
The cause is the weak hydrogen bonds that occur between water molecules. On smaller raindrops, the surface tension is stronger than in larger drops. The reason is the flow of air around the drop. As the raindrop falls, it loses that rounded shape.
What conditions favor the collision coalescence process?
What conditions favor the collision-coalescence process? created by a layer of air with above freezing temperatures covering a layer of air with subfreezing temperatures. When rain drops fall through the air layers, the freeze while passing through the colder layer.
Is condensation a warming or cooling process?
Condensation has a phase change from gas to liquid. Condensation is the warming process. Heat energy is released by the gas when it condenses into a liquid.
Does rain remove humidity?
Connection of Rain and Humidity When it rains, it will increase the relative humidity because of the evaporation. On a larger scale, rain will remove water vapor through air condensation and deposit it on the surface. This means that across larger volumes, the average relative humidity reduces through rain.
Which is the most humid place on Earth?
The most humid places on earth are tropical seashores, such as Southeast Asia , the Congo river, and coastal cities worldwide. These places register 100% humidity consistently. New Orleans is not more humid than the Amazon River Basin, but only because 100% is as humid as it gets.
Which is world’s hottest city?
