ATM S 111 Lecture Notes - Lecture 1: Ocean Heat Content, Western Interior Seaway, Shortwave Radiation
Document Summary
Average weather conditions over a long period of time. Climate is the fact that storms hit western washington. Weather: the condition of the atmosphere at a speci c time and place. Both weather and climate can be predicted with some delity. Environment, vegetation, close to equator, topography (altitude), latitude(sunshine), proximity to ocean, ocean currents(atmospheric circulation) 90% of the atmosphere is within about 16km (10 miles) of the surface of earth. Proportionally, the atmosphere is half as thin as seams on a basketball, very thin. A thin atmosphere means that we can change our atmospheric composition. We modify the composition of the atmosphere. Carbon has been measured at mauna loa, hawaii, since 1958. Keeling curve : rst measured by david keeling in march 1958. Over 25% increase since the rst measurement. Human induced: due to fossil fuel burning (90%) and deforestation (10%) Industrial revolution caused a rise in co2, can see ice age cycles.
