Document Summary
30 years mean climate of toronto is 22. 2: weather can report max, min temperature and rain, to report extremes, need more time period change of temperature- climate, midlatitude cities have the most distinct 4 seasons. Land cover: albedo, evepotranspiration, heat capacity, higher amount of precipitation. 2 types: positive, negative, change in a will cause change in b, that change in b will cause change in a in that same direction it is called position feedback, if opposite direction- negative feedback. Albedo: highest albedo for fresh snow, thick clouds are higher reflective, thin clouds have lower albedo, warming causes reduction of ice and snow, less ice and snow reduces reflectivity, which causes more warming= positive feedback.
