Document Summary
Lecture 9: what is a volcano? last class: the butterfly effect. 1950s: some people thought that long-range weather control was possible. However, we now know that weather is a chaotic system. Figure: the chaotic system was first looked at by lorenz. Even though the initial conditions of the two weather patterns are virtually the same, the trajectory grows farther apart until all resemblance disappears last class: ensemble of forecasts, based on perturbed initial conditions. 1987 england forecast was appropriate based on initial conditions. October 1897 storm ensemble reforecast includes perturbed initial conditions. Displays forecasts based on different initial conditions. Incorrect 1987 forecast was due to the chaotic nature of weather. A volcano is an opening in earth"s crust that allows warm material to escape to earth"s surface. Active : a volcano that has recently erupted (i. e. in the last 10,000 years) Dormant : a volcano that has not erupted recently but is capable of erupting again.
