Bogging most often occurs in most peoples cars when they leave the car in a high gear, and when trying to accelrate the car "bogs". It kind of chugs. I think it's a series of misfires.
Pressure will tend to slightly raise saturation point, increased temperature tends to greatly raise it. Hence rain when air cools, and lower pressure signals rain. Also, you can see that warm air can hold a great deal more water. At 50 F, air will hold about 4 g per cubic foot, and at 90 F, about 14 g per cubic foot.
At 30 psi, 50 F holds the same 4 g per cu ft. At 90F, 30 psi, sat. air holds 15 g per cu ft.

dry=wet bulb temp equals 100% saturation of air.
