Document Summary
Chapter 3: climate and weather. Releases pyrolcastic flows as ash, aerosols, gases (so2, h2o(l)) They can be projected 30km into atmosphere- so rad. Took to global wind patterns and dropped global patterns by 0. 5 degrees celsius. Pyroclastic flows circle the globe, travelling towards poles. No temperature change, just state change. A transfer of energy occurs- latent heat: state change. Latent! hidden heat! works for any state change. Energy can flow by conduction (direct contact) and by radiation and by convection (movement of warm/cold fluids/gases) Advection!horizontal (lateral) movement of fluids/gases. Typically have a change in temperature, sometimes a change in state. Note definition of heat radiation (the ratio of incoming/outgoing solar radiation) Fluxuations from zone to zone. There is always a lag before things heat up/cool down. Take a look at the graphs in the textbook. Coastal locations get moderate weather compared to inland. Water takes longer to warm up, but longer to cool down.
