Document Summary

** for every 1km up the most fluctuation can happen is 10 degrees. Green: on the x & y plane. Taking a slice of the atmosphere and looking at it from the ground. ** dont think of cold or warm fronts in the upper atmosphere because in the upper atmosphere the high and low pressure are co located so they don"t move around. Removing molecules from the column causing the pressure to drop at the surface. The air entering is entering in a higher speed than leaving. Accumulating molecules which developed a high pressure system at the surface. The air is entering at a slow rate than leaving. Which causes a low pressure system at the surface. Need to bring air to dew point temp. Create fog or dew forming, ice crystals. As air rises, the pressure drops and expands and drop in temp. How much moister, how close we air to saturation.
