Topographical effects: 2) The map below shows the contour lines of the annual average wind speed from April 2004 till March 2005. This map is derived from a computer model of climate. This makes it possible to extend the contour lines to places like high mountain ridges or over water, where it would not be possible or feasible to measure wind speed using weather stations. A description of how a computer model can generate such data is beyond the scope of this course, so we won't elaborate on it. You can take it for granted that the figure is close to reality. The next figure below provides a conceptual picture of how air interacts with topography (dynamic effects). The schemes provided here have been discussed in the lecture. Indicate on each region of New Zealand (map is provided below), which dynamic effect(s) dominate(s) wind climatology [Hint: there might be more than one].

Can you relate the contour lines of wind speed generated by the computer with these conceptual diagrams? Comment on the Jet in Cook Stralt. What is the wind speed climate in West Coast of South Island? Is the West Coast a good resource or a poor resource for wind energy? Why?
