EESB03H3 Lecture Notes - Lecture 6: Supercooling, Rain Gauge, Stevenson Screen
Document Summary
No special topic lecture today, up until todays lecture=on midterm. Ideal gas law= p=ptxc c=gas constant at a given pressure, colder air is more dense. @diff locations= abcd= for every 100m increase=lose 10mb of pressure, so when bring down from upper level, pressure gains mb greatest change at c, location d is maintained pressure changes unless along isobars. 5600m to compare pressure diff, pressure must be reduced to sea level on surface chart=see ridges / troughs formesd in upper atmosphere region formation of ridge=warm air coming into area cold air=get some sort of trough. R= gas constant, g gravity and t avg temp=> h=rt/g. Inverse relationship, increase height, pressure decreases (related to quiz 5 materials) Humidity=evap and condensation occurring to maintain equilibrium= not net increase or decrease of water vapor in the system. Water vapour : saturation of vap pressure depends on temp condition=cold air holds less water. Rh=ratio of water vap in air compared to maximum(a percentage/proportion)
