So, there are some common misconceptions with rain and allergies along with the general shape of the awe-inspiring particulate. Let's start with the shape:
A water droplet is a perfect sphere. Not the tear-drop shape that has been permeating through textbooks and writings everywhere for all of history. The easiest way to demonstrate would be to look at a leaking faucet. Drip goes the drop, and oh look, it is perfectly round.
In relation to allergies, rain has always been seen as a hero to allergy-sufferers.
The common belief is that the rain washes the pollen and/or other allergens out of the air. However, that is not the case. What actually happens is that on rainy days, the rain arouses the pollen on the ground and actually gets the allergens airborne once again. The following dry period is spent on the pollen re-collecting back onto the ground again. Think of the action like punching dust or flour. What happens? Some of the particulates are splashed back up into the atmosphere, and then slowly settle back down. Same sort of thing happens with rainfall and pollen. Otherwise, after all the trees released their pollen, it would move around and settle quickly, unless you have a storm come through that provides some rain and wind to give the pollen some uplifting motions again.
Remembering this from TWC, one of the few times I have ever learned something interesting from them. Kudos to TWC for that!
