Document Summary
Lecture 16: climate is based on long term observation. Often more local: radiation , things like the amount of insolation. So, climate perspective would be mcgill had meteorological station since 1895. Avg temperature or min or max, for nov 7th, average from (cid:1006)(cid:1004)(cid:1005)(cid:1011) (cid:271)a(cid:272)k ti (cid:1005)(cid:1013)(cid:1012)(cid:1009), that"s (cid:272)li(cid:373)ate pe(cid:396)spe(cid:272)ti(cid:448)e. meteorology says what happens on nov 7 2017. Atmospheric pressure, how cyclones and anticyclones influence climate. So (cid:449)e"ll ofte(cid:374) look to western horizon to see what our weather will be next: humidity, relative humidity specific humidity how much vapor is present that gives us an diea of how much precipitation is possible. Etc. and the amount: some of the factors that influence climate is latitude. Photoperiod decreases: mean or avg air temperature decreases as we go poleward, range of temperature gets wider in midlatitudes, then narrow again in higher latitudes, specific humidity decreases with latitude, many global patterns shift latitudinally. Lower atmospheric density in a highland results in:
