As a fello colorodoan, and fiber optics engineer I'm qualified to help add to the other answers,
Most of the other comments are accurate about pollen, humidity, etc. A few things left out is the marijuana haze from increased outdoor consumption, an increase in air pollution due to increased vehicle usage, the mirage effect is also more prevalent in Colorado during summer because the relative temperature between the mountain peaks and the plains is relatively similar during winter (A LOT of factors in this), and if you're on the eastern plains looking at the mountains in colorado the contrast plus angle of the sun in winter makes the mountains brighter and stand out more for a lot longer in the day. During the summer if youre up early enough on a cold day in summer the mountains will stand out more than at like noon.

>Even if the max velocity of the water is the same in the pool (ie a very slow rotation rate) then the energy of the water will scale somewhat with the volume of the water, ie cubicly, while the drag of the walls will scale somewhat with the area of the side walls, ie. squared, therefore the larger the cup, the more the kinetic energy of the water outweighs the drag of the sides.
The centripetal force increases friction aswell angular momentum. So it increases the energy lost due to friction aswell as the increase in surface area.

Not the right kind of engineer but I'll give 'er a swing. (Fiber Optic and Network engineer)
Let's say all external input variables are the same. As in everything is the same except one is occurring at a 152,000 x scale (2 cups of water vs standard pool at 19000 gallons or 340,000 cups)
My semi-educated guess: We assume conservation of momentum and the same angular velocity.
The surface-area-to-volume ratio decreases with increasing volume. Therefore the pool-sized mug will experience less force of friction relative to the increase in mass/volume.
An increase in volume increases the radius and mass. Therefore the linear velocity at the edge is much higher as mentioned in another comment causing an increase in centrifugal force causing an increase in friction for the pool.

Figured out how to figure it out as long as the correct answer doesn't involve calculus cause I ain't got time for that. Do the math for two spinning cylinders with friction at the edge.

Yea I was just informing that the surface area increase also correlates with an increase in normal force. Idk how it interacts just that it was missed.
