ESS205H1 Study Guide - Midterm Guide: Intertropical Convergence Zone, Polar Easterlies, Hadley Cell
Document Summary
Hydrosphere: water cycle, tree and other plants slow the flow of rainwater to rivers, acting as a nature flood control. Water reservoirs (residence time): ocean (1000yr), cryosphere (1000yr, ice caps and glaciers, temperature sea level), groundwater (2wk-1000yr), surface water (2wk-10yr), soils, atmosphere(10ds), biosphere (1d-yrs) Water/hydrologic cycle: water move from reservoir to reservoir (16%) (23%), evapotranspiration precipitation condensation, underground flow, penetration (infiltrating) into soil, run off (7%), ocean: evaporation (84%), precipitation (77%), transport by wind (7%) Ocean: 70% of surface, max. depth 11km in marianas, ave. depth 3. 8km heat: from the sun (tropical), distribute by currents. Deep currents: temperature/ salinity-driven, not directly affected by winds, takes 1000yrs. Equatorial: low pressure, cloudiness and heavy precipitation. 60 latitude: he area around 60 n and s is an area in which air from the ferrel and weak polar cells converges and is uplifted, creating an area of high pressure (middle-latitude depression, e. g. unsettled weather in europe)
